all events a lucid Venetian picture--hangs next the St. George of
Correggio. After looking at the latter, the Venetian work appears
glassy and unsubstantial, but on reversing the order of comparison,
the Correggio may be said to suffer more, and for a moment its fine
transitions of light and shade seem changed to heaviness.
[22] The finest works of Tintoret---the Crucifixion and the Miracolo
del Servo (considered here merely with reference to their colour,)
may be said to combine the excellences of Titian and Giacomo Bassan,
on a grand scale; the sparkling clearness of the latter is one of the
prominent characteristics of these pictures. Tintoret is reported to
have once said that a union of his own knowledge of form with Bassan's
colour would be the perfection of painting. See "Verei Notizie de'
Pittori di Bassano;" Ven. 1775, p. 61.
[23] That this last quality, the characteristic of Bassan's best
pictures, was held in high estimation by Paul Veronese, is not only
evident from that painter's own works, but from the circumstance of his
preferring to place his sons with Bassan rather than with any other
painter. (See "Boschini Carta del Navegar," p. 280.) The Baptism of
Sta. Lucilla, in Boschini's time considered the finest of Giacomo's
works, is still in the church of S. Valentino, at Bassano, and may be
considered the type of the lucid and sparkling manner.
NOTE F.--Par. 83.
The author, in these instances, seems to be anticipating his
subsequent explanations on the effect of semi-transparent mediums.
For an explanation of the general view contained in these paragraphs
respecting the gradual increase of colour from high light, see the last
Note.
The anonymous French work before alluded to, among other interesting
examples, contains a chapter on shadows cast by the upper light of the
sky and coloured by the setting sun. The effect of this remarkable
combination is, that the light on a wall is most coloured immediately
under a projecting roof, and becomes comparatively neutralised in
proportion to its distance from the edge of the darkest shade.
NOTE G.--Par. 98.
"The simplest case of the phenomenon, which Goethe calls a subjective
halo, and one which at once explains its cause, is the following.
Regard a red wafer on a sheet of white paper, keeping the eye
stedfastly fixed on a point at its center. When the retina is
fatigued, withdraw the head a little from the paper, and a green halo
will appear to surround the wafer. By this slight increase of distance
the image of the wafer itself on the retina becomes smaller, and the
ocular spectrum which before coincided with the direct image, being
now relatively larger, is seen as a surrounding ring."--S. F. Goethe
mentions cases of this kind, but does not class them with subjective
halos. See Par. 30.
NOTE H.--Par. 113.
"Cases of this kind are by no means uncommon. Several interesting
ones are related in Sir John Herschell's article on Light in the
Encyclopædia Metropolitana. Careful investigation has, however, shown
that this defect of vision arises in most, if not in all cases, from
an inability to perceive the red, not the blue rays. The terms are so
confounded by the individuals thus affected, that the comparison of
colours in their presence is the only criterion."--S. F.
NOTE I.--Par. 135.
The author more than once admits that this chapter on "Pathological
Colours" is very incomplete, and expresses a wish (Par. 734) that some
medical physiologists would investigate the subject further. This was
afterwards in a great degree accomplished by Dr. Johannes Müller, in
his memoir "Über die Phantastischen Gesichtserscheinungen." Coblentz,
1826. Similar phenomena have been also investigated with great labour
and success by Purkinje. For a collection of extraordinary facts of the
kind recorded by these writers, the reader may consult Scott's Letters
on Demonology and Witchcraft.[1] The instances adduced by Müller and
others are, however, intended to prove the inherent capacity of the
organ of vision to produce light and colours. In some maladies of the
eye, the patient, it seems, suffers the constant presence of light
without external light. The exciting principle in this case is thus
proved to be within, and the conclusion of the physiologists is that
external light is only one of the causes which produce luminous and
coloured impressions. That this view was anticipated by Newton may be
gathered from the concluding "query" in the third book of his Optics.

Mount Athos, in Gibbon, chap. 63.
NOTE K.--Par. 140.
"Catoptrical colours. The colours included under this head are
principally those of fibres and grooved surfaces; they can be produced
artificially by cutting parallel grooves on a surface of metal from
2000 to 10,000 in the inch. See 'Brewster's Optics,' p. 120. The
colours called by Goethe _paroptical_, correspond with those produced
by the diffraction or inflection of light in the received theory.--See
Brewster, p. 95. The phenomena included under the title 'Epoptical
Colours,' are generally known as the colours of thin plates. They vary
with the thickness of the film, and the colour seen by reflection
always differs from that seen by transmission. The laws of these
phenomena have been thoroughly investigated. See Nobili, and Brewster,
p. 100."--S. F.
The colours produced by the transmission of polarised light through
chrystalised mediums, were described by Goethe, in his mode,
subsequently to the publication of his general theory, under the name
of Entoptic Colours. See note to Par. 485.
NOTE L.--Par. 150.
We have in this and the next paragraph the outline of Goethe's system.
The examples that follow seem to establish the doctrine here laid
down, but there are many cases which it appears cannot be explained on
such principles: hence, philosophers generally prefer the theory of
absorption, according to which it appears that certain mediums "have
the property of absorbing some of the component rays of white light,
while they allow the passage of others."[1]
Whether all the facts adduced by Goethe--for instance, that recorded
in Par. 172, are to be explained by this doctrine, we leave to the
investigators of nature to determine. Dr. Eckermann, in conversing with
Goethe, thus described the two leading phenomena (156, 158) as seen by
him in the Alps. "At a distance of eighteen or twenty miles at mid-day
in bright sunshine, the snow appeared yellow or even reddish, while the
dark parts of the mountain, free from snow, were of the most decided
blue. The appearances did not surprise me, for I could have predicted
that the mass of the interposed medium would give a deep yellow tone
to the white snow, but I was pleased to witness the effect, since it
so entirely contradicted the erroneous views of some philosophers,
who assert that the air has a blue-tinging quality. The observation,
said Goethe, is of importance, and contradicts the error you allude to
completely."[2]
The same writer has some observations to the same effect on the colour
of the Rhone at Geneva. A circumstance of an amusing nature which he
relates in confirmation of Goethe's theory, deserves to be inserted.
"Here (at Strasburg), passing by a shop, I saw a little glass bust
of Napoleon, which, relieved as it was against the dark interior of
the room, exhibited every gradation of blue, from milky light blue
to deep violet. I foresaw that the bust seen from within the shop
with the light behind it, would present every degree of yellow, and I
could not resist walking in and addressing the owner, though perfectly
unknown to me. My first glance was directed to the bust, in which, to
my great joy, I saw at once the most brilliant colours of the warmer
kind, from the palest yellow to dark ruby red. I eagerly asked if I
might be allowed to purchase the bust; the owner replied that he had
only lately brought it with him from Paris, from a similar attachment
to the emperor to that which I appeared to feel, but, as my ardour
seemed far to surpass his, I deserved to possess it. So invaluable
did this treasure seem in my eyes, that I could not help looking at
the good man with wonder as he put the bust into my hands for a few
franks. I sent it, together with a curious medal which I had bought
in Milan, as a present to Goethe, and when at Frankfort received the
following letter from him." The letter, which Dr. Eckermann gives
entire, thus concludes--"When you return to Weimar you shall see the
bust in bright sunshine, and while the transparent countenance exhibits
a quiet blue,[3] the thick mass of the breast and epaulettes glows with
every gradation of warmth, from the most powerful ruby-red downwards;
and as the granite statue of Memnon uttered harmonious sounds, so the
dim glass image displays itself in the pomp of colours. The hero is
victorious still in supporting the Farbenlehre."[4]
One effect of Goethe's theory has been to invite the attention of
scientific men to facts and appearances which had before been unnoticed
or unexplained. To the above cases may be added the very common, but
very important, fact in painting, that a light warm colour, passed in
a semi-transparent state over a dark one, produces a cold, bluish
hue, while the operation reversed, produces extreme warmth. On the
judicious application of both these effects, but especially of the
latter, the richness and brilliancy of the best-coloured pictures
greatly depends. The principle is to be recognised in the productions
of schools apparently opposite in their methods. Thus the practice
of leaving the ground, through which a light colour is apparent, as
a means of ensuring warmth and depth, is very common among the Dutch
and Flemish painters. The Italians, again, who preferred a solid
under-painting, speak of internal light as the most fascinating quality
in colour. When the ground is entirely covered by solid painting, as
in the works of some colourists, the warmest tints in shadows and
reflections have been found necessary to represent it. This was the
practice of Rembrandt frequently, and of Reynolds universally, but the
glow of their general colour is still owing to its being repeatedly
or ultimately enriched on the above principle. Lastly, the works of
those masters who were accustomed to paint on dark grounds are often
heavy and opaque; and even where this influence of the ground was
overcome, the effects of time must be constantly diminishing the warmth
of their colouring as the surface becomes rubbed and the dark ground
more apparent through it. The practice of painting on dark grounds was
intended by the Carracci to compel the students of their school to
aim at the direct imitation of the model, and to acquire the use of
the brush; for the dark ground could only be overcome by very solid
painting. The result answered their expectations as far as dexterity of
pencil was concerned, but the method was fatal to brilliancy of colour.
An intelligent writer of the seventeenth century[5] relates that Guido
adopted his extremely light style from seeing the rapid change in some
works of the Carracci soon after they were done. It is important,
however, to remark, that Guido's remedy was external rather than
internal brilliancy; and it is evident that so powerless a brightness
as white paint can only acquire the splendour of light by great
contrast, and, above all, by being seen through external darkness. The
secret of Van Eyck and his contemporaries is always assumed to consist
in the vehicle (varnish or oils) he employed; but a far more important
condition of the splendour of colour in the works of those masters was
the careful preservation of internal light by painting thinly, but
ultimately with great force, on white grounds. In some of the early
Flemish pictures in the Royal Gallery at Munich, it may be observed,
that wherever an alteration was made by the painter, so that a light
colour is painted over a dark one, the colour is as opaque as in any
of the more modern pictures which are generally contrasted with such
works. No quality in the vehicle could prevent this opacity under such
circumstances; and on the other hand, provided the internal splendour
is by any means preserved, the vehicle is comparatively unimportant.
It matters not (say the authorities on these points) whether the effect
in question is attained by painting thinly over the ground, in the
manner of the early Flemish painters and sometimes of Rubens, or by
painting a solid light preparation to be afterwards toned to richness
in the manner of the Venetians. Among the mechanical causes of the
clearness of colours superposed on a light preparation may be mentioned
that of careful grinding. All writers on art who have descended to
practical details have insisted on this. From the appearance of some
Venetian pictures it may be conjectured that the colours of the
solid under-painting were sometimes less perfectly ground than the
scumbling colours (the light having to pass through the one and to
be reflected from the other). The Flemish painters appear to have
used carefully-ground pigments universally. This is very evident in
Flemish copies from Raphael, which, though equally impasted with
the originals, are to be detected, among other indications, by the
finely-ground colours employed.
[1] See "Müller's Elements of Physiology," translated from the German
by William Baly, M.D. "The laws of absorption," it has been observed,
"have not been studied with so much success as those of other phenomena
of physical optics, but some excellent observations on the subject
will be found in Herschell's Treatise on Light in the Encyclopædia
Metropolitana, § III."
[2] "Eckermann's Gespräche mit Goethe," vol. ii. p. 280. Leonardo da
Vinci had made precisely the same observation. "A distant mountain will
appear of a more beautiful blue in proportion as it is dark in colour.
The illumined air, interposed between the eye and the dark mass, being
thinner towards the summit of the mountain, will exhibit the darkness
as a deeper blue and _vice versâ_."--_Trattato della Pittura_, p. 143.
Elsewhere--"The air which intervenes between the eye and dark mountains
becomes blue; but it does not become blue in (before) the light part,
and much less in (before) the portion that is covered with snow."--p.
244.
[3] This supposes either that the mass was considerably thicker, or
that there was a dark ground behind the head, and a light ground behind
the rest of the figure.

NOTE M.--Par. 177.
Without entering further into the scientific merits or demerits of
this chapter on the "First Class of Dioptrical Colours," it is to be
observed that several of the examples correspond with the observations
of Leonardo da Vinci, and again with those of a much older authority,
namely, Aristotle. Goethe himself admits, and it has been remarked by
others, that his theory, in many respects, closely resembles that of
Aristotle: indeed he confesses[1] that at one time he had an intention
of merely paraphrasing that philosopher's Treatise on Colours.[2]
We have already remarked (Note on par. 150) that Goethe's notion with
regard to the production of warm colours, by the interposition of dark
transparent mediums before a light ground, agrees with the practice of
the best schools in colouring; and it is not impossible that the same
reasons which may make this part of the doctrine generally acceptable
to artists now, may have recommended the very similar theory of
Aristotle to the painters of the fifteenth and sixteenth centuries:
at all events, it appears that the ancient theory was known to those
painters.
It is unnecessary to dwell on the fact that the doctrines of Aristotle
were enthusiastically embraced and generally inculcated at the period
in question;[3] but it has not been observed that the Italian writers
who translated, paraphrased, and commented on Aristotle's Treatise
on Colours in particular, were in several instances the personal
friends of distinguished painters. Celio Calcagnini[4] had the highest
admiration for Raphael; Lodovico Dolce[5] was the eulogist of Titian;
Portius,[6] whose amicable relations with the Florentine painters may
be inferred from various circumstances, lectured at Florence on the
Aristotelian doctrines early in the sixteenth century. The Italian
translations were later, but still prove that these studies were
undertaken with reference to the arts, for one of them is dedicated to
the painter Cigoli.[7]
The writers on art, from Leon Battista Alberti to Borghini, without
mentioning later authorities, either tacitly coincide with the
Aristotelian doctrine, or openly profess to explain it. It is true this
is not always done in the clearest manner, and some of these writers
might say with Lodovico Dolce, "I speak of colours, not as a painter,
for that would be the province of the divine Titian."
Leonardo da Vinci in his writings, as in everything else, appears as
an original genius. He now and then alludes generally to opinions
of "philosophers," but he quotes no authority ancient or modern.
Nevertheless, a passage on the nature of colours, particularly where
he speaks of the colours of the elements, appears to be copied from
Leon Battista Alberti,[8] and from the mode in which some of Leonardo's
propositions are stated, it has been supposed[9] that he had been
accustomed at Florence to the form of the Aristotelian philosophy. At
all events, some of the most important of his observations respecting
light and colours, have a great analogy with those contained in the
treatise in question. The following examples will be sufficient to
prove this coincidence; the corresponding passages in Goethe are
indicated, as usual, by the numbers of the paragraphs; the references
to Leonardo's treatise are given at the bottom of the page.
Aristotle.
"A vivid and brilliant red appears when the weak rays of the
sun are tempered by subdued and shadowy white,"--154.
Leonardo
"The air which is between the sun and the earth at sun-rise
or sun-set, always invests what is beyond it more than any
other (higher) portion of the air: this is because it is
whiter."[10]
A bright object loses its whiteness in proportion to its
distance from the eye much more when it is illuminated by
the sun, for it partakes of the colour of the sun mingled
with the colour (tempered by the mass) of the air interposed
between the eye and the brightness.[11]
Aristotle.
"If light is overspread with much obscurity, a red colour
appears; if the light is brilliant and vivid, this red
changes to a flame-colour."[12]--150, 160.
Leonardo.
"This (the effect of transparent colours on various grounds)
is evident in smoke, which is blue when seen against black,
but when it is opposed to the (light) blue sky, it appears
brownish and reddening."[13]
Aristotle.
"White surfaces as a ground for colours, have the effect of
making the pigments[14] appear in greater splendour."--594,
902.
Leonardo.
"To exhibit colours in their beauty, the whitest ground
should be prepared. I speak of colours that are (more or
less) transparent."[15]
Aristotle.
"The air near us appears colourless; but when seen in depth,
owing to its thinness it appears blue;[16] for where the
light is deficient (beyond it), the air is affected by the
darkness and appears blue: in a very accumulated state,
however, it appears, as is the case with water, quite
white."--155, 158.
Leonardo.
"The blue of the atmosphere is owing to the mass of
illuminated air interposed between the darkness above and
the earth. The air in itself has no colour, but assumes
qualities according to the nature of the objects which are
beyond it. The blue of the atmosphere will be the more
intense in proportion to the degree of darkness beyond it:"
elsewhere--"if the air had not darkness beyond it, it would
be white."[17]
Aristotle.
"We see no colour in its pure state, but every hue is
variously intermingled with others: even when it is
uninfluenced by other colours, the effect of light and
shade modifies it in various ways, so that it undergoes
alterations and appears unlike itself. Thus, bodies seen in
shade or in light, in more pronounced or softer sun-shine,
with their surfaces inclined this way or that, with every
change exhibit a different colour."
Leonardo.
"No substance will ever exhibit its own hue unless the light
which illumines it is entirely similar in colour. It very
rarely happens that the shadows of opaque bodies are really
similar (in colour) to the illumined parts. The surface of
every substance partakes of as many hues as are reflected
from surrounding objects."[18]
Aristotle.
"So, again, with regard to the light of fire, of the moon,
or of lamps, each has a different colour, which is variously
combined with differently coloured objects."
Leonardo.
"We can scarcely ever say that the surface of illumined
bodies exhibits the real colour of those bodies. Take a
white band and place it in the dark, and let it receive
light by means of three apertures from the sun, from fire,
and from the sky: the white band will be tricoloured."[19]
Aristotle.
"When the light falls on any object and assumes (for
example) a red or green tint, it is again reflected on other
substances, thus undergoing a new change. But this effect,
though it really takes place, is not appreciable by the
eye: though the light thus reflected to the eye is composed
of a variety of colours, the principal of these only are
distinguishable."
Leonardo.
"No colour reflected on the surface of another colour,
tinges that surface with its own colour (merely), but will
be mixed with various other reflections impinging on the
same surface:" but such effects, he observes elsewhere, "are
scarcely, if at all, distinguishable in a very diffused
light."[20]
Aristotle.
"Thus, all combinations of colours are owing to three
causes: the light, the medium through which the light
appears, such as water or air, and lastly the local colour
from which the light happens to be reflected."
Leonardo.
"All illumined objects partake of the colour of the light
they receive.
"Every opaque surface partakes of the colour of the
intervening transparent medium, according to the density of
such medium and the distance between the eye and the object.
"The medium is of two kinds; either it has a surface, like
water, &c., or it is without a common surface, like the
air."[21]
In the observations on trees and plants more points of resemblance
might be quoted; the passages corresponding with Goethe's views are
much more numerous.
It is remarkable that Leonardo, in opposition, it seems to some
authorities,[22] agrees with Aristotle in reckoning black and white
as colours, placing them at the beginning and end of the scale.[23]
Like Aristotle, again, he frequently makes use of the term black, for
obscurity; he even goes further, for he seems to consider that blue
may be produced by the actual mixture of black and white, provided they
are pure.[24] The ancient author, however, explains himself on this
point as follows--"We must not attempt to make our observations on
these effects by mixing colours as painters mix them, but by remarking
the appearances as produced by the rays of light mingling with each
other."[25]
When we consider that Leonardo's Treatise professes to embrace the
subject of imitation in painting, and that Aristotle's briefly examines
the physical nature and appearance of colours, it must be admitted
that the latter sustains the above comparison with advantage; and it
is somewhat extraordinary that observations indicating so refined a
knowledge of nature, as regards the picturesque, should not have been
taken into the account, for such appears to be the fact, in the various
opinions and conjectures that have been expressed from time to time on
the painting of the Greeks. The treatise in question must have been
written when Apelles painted, or immediately before; and as a proof
that Aristotle's remarks on the effect of semi-transparent mediums were
not lost on the artists of his time, the following passage from Pliny
is subjoined, for, though it is well known, it acquires additional
interest from the foregoing extracts.
"He (Apelles) passed a dark colour over his pictures when finished, so
thin that it increased the splendour of the tints, while it protected
the surface from dust and dirt: it could only be seen on looking into
the picture. The effect of this operation, judiciously managed, was to
prevent the colours from being too glaring, and to give the spectator
the impression of looking through a transparent crystal. At the same
time it seemed almost imperceptibly to add a certain dignity of tone to
colours that were too florid." "This," says Reynolds, "is a true and
artist-like description of glazing or scumbling, such as was practised
by Titian and the rest of the Venetian painters."
The account of Pliny has, in this instance, internal evidence
of truth, but it is fully confirmed by the following passage in
Aristotle:--"Another mode in which the effect of colours is exhibited
is when they appear through each other, as painters employ them when
they glaze (ἐπαλειφοντες)[26] a (dark) colour over a lighter one; just
as the sun, which is in itself white, assumes a red colour when seen
through darkness and smoke. This operation also ensures a variety of
colours, for there will be a certain ratio between those which are on
the surface and those which are in depth."--_De Sensu et Sensili_.
Aristotle's notion respecting the derivation of colours from white and
black may perhaps be illustrated by the following opinion on the very
similar theory of Goethe.
"Goethe and Seebeck regard colour as resulting from the mixture of
white and black, and ascribe to the different colours a quality
of darkness (σκιερὸν), by the different degrees of which they are
distinguished, passing from white to black through the gradations
of yellow, orange, red, violet, and blue, while green appears to be
intermediate again between yellow and blue. This remark, though it has
no influence in weakening the theory of colours proposed by Newton,
is certainly correct, having been confirmed experimentally by the
researches of Herschell, who ascertained the relative intensity of the
different coloured rays by illuminating objects under the microscope by
their means, &c.
"Another certain proof of the difference in brightness of the different
coloured rays is afforded by the phenomena of ocular spectra. If, after
gazing at the sun, the eyes are closed so as to exclude the light, the
image of the sun appears at first as a luminous or white spectrum upon
a dark ground, but it gradually passes through the series of colours to
black, that is to say, until it can no longer be distinguished from the
dark field of vision; and the colours which it assumes are successively
those intermediate between white and black in the order of their
illuminating power or brightness, namely, yellow, orange, red, violet,
and blue. If, on the other hand, after looking for some time at the
sun we turn our eyes towards a white surface, the image of the sun is
seen at first as a black spectrum upon the white surface, and gradually
passes through the different colours from the darkest to the lightest,
and at last becomes white, so that it can no longer be distinguished
from the white surface"[27]--See par 40, 44.
It is not impossible that Aristotle's enumeration of the colours may
have been derived from, or confirmed by, this very experiment. Speaking
of the after-image of colours he says, "The impression not only exists
in the sensorium in the act of perceiving, but remains when the organ
is at rest. Thus if we look long and intently on any object, when
we change the direction of the eyes a responding colour follows. If
we look at the sun, or any other very bright object, and afterwards
shut our eyes, we shall, as if in ordinary vision, first see a colour
of the same kind; this will presently be changed to a red colour,
then to purple, and so on till it ends in black and disappears."--_De
Insomniis_.

1833.
[2] The treatise in question is ascribed by Goethe to Theophrastus,
but it is included in most editions of Aristotle, and even attributed
to him in those which contain the works of both philosophers; for
instance, in the Aldine Princeps edition, 1496. Calcagnini says, the
treatise is made up of two separate works on the subject, both by
Aristotle.
[3] His authority seems to have been equally great on subjects
connected with the phenomena of vision; the Italian translator of
a Latin treatise, by Portius, on the structure and colours of the
eye, thus opens his dedication to the Cardinal Ercole Gonzaga, of
Mantua:--"Grande anzi quasi infinito è l'obligo che ha il mondo con
quel più divino che umano spirito di Aristotile."
[4] In a letter to Ziegler the mathematician, Calcagnini speaks of
Raphael as "the first of painters in the theory as well as in the
practice of his art." This expression may, however, have had reference
to a remarkable circumstance mentioned in the same letter, namely,
that Raphael entertained the learned Fabius of Ravenna as a constant
guest, and employed him to translate Vitruvius into Italian. This MS.
translation, with marginal notes, written by Raphael, is now in the
library at Munich. "Passavant, Rafael von Urbino."
[5] Lodovico Dolce's Treatise on Colours (1565) is in the form of a
dialogue, like his "Aretino." The abridged theory of Aristotle is
followed by a translation of the Treatise of Antonius Thylesius on
Colours; this is adapted to the same colloquial form, and the author is
not acknowledged: the book ends with an absurd catalogue of emblems.
The "Somma della Filosofia d'Aristotile," published earlier by the same
author, is a very careless performance.
[6] A Latin translation of Aristotle's Treatise on Colours, with
comments by Simon Portius, was first published, according to Goethe,
at Naples in 1537. In a later Florentine edition, 1548, dedicated to
Cosmo I., Portius alludes to his having lectured at an earlier period
in Florence on the doctrines of Aristotle, at which time he translated
the treatise in question. Another Latin translation, with notes, was
published later in the same century at Padua--"Emanuele Marguino
Interprete:" but by far the clearest view of the Aristotelian theory
is to be found in the treatise of Antonio Vidi Scarmiglione of Fuligno
("De Coloribus," Marpurgi, 1591). It is dedicated to the Emperor
Rudolph II. Of all the paraphrases of the ancient doctrine this comes
nearest to the system of Goethe; but neither this nor any other of the
works alluded to throughout this Note are mentioned by the author in
his History of the Doctrine of Colours, except that of Portius.
[7] An earlier Italian translation appeared in Rome, 1535. See
"Argelatus Biblioteca degli Volgarizzatori."
[8] "Della Pittura e della Statua," Lib. I, p. 16, Milan edition,
1804. Compare with the "Trattato della Pittura," p. 141. Other points
of resemblance are to be met with. The notion of certain colours
appropriated to the four elements, occurs in Aristotle, and is indeed
attributed to older writers.

[12] In the Treatise _De Igne_, by Theophrastus, we find the same
notion thus expressed: "Brightness (_τὸ λευκὸν_) seen through a
dark coloured medium (_διὰ του μέλανος_) appears red; as the sun
seen through smoke or soot: hence the coal is redder than the
flame." Scarmiglione, from whom Kircher seems to have copied,
observes:--"Itaque color realis est lux opaca; licet id e plurimis
apparentiis colligere. Luna enim in magnâ solis eclipsi rubra
conspicitur, quia tenebris lux præpeditur ac veluti tegitur."--_De
Coloribus_.
[13] Page 122.
[14] _Τὰ ἂνθη_: translated _flores_ by Calcagnini and the rest, by
Goethe, _die Blüthe_, the bloom. That the word sometimes signified
pigments is sufficiently apparent from the following passage of
Suidas (quoted by Emeric David, "Discours Historiques sur la Peinture
Moderne") _ἂνθεσι κεκοσμημέναι, οἶον ψιμμιωίῳ φύκει καὶ τοῖς ὸμοίοις_.
Variis pigmentis ornatæ, ut cerussâ, fuco, et aliis similibus. (Suid.
in voc. _Ἐξμηθισμένας_.) A panel prepared for painting, with a white
ground consolidated with wax, and perhaps mastic, was found in

διὰ τὴν ὰραιότητα._ "But when seen in depth, it appears (even) in its
nearest colour, blue, owing to its thinness." The Latin interpretations
vary very much throughout. The point which is chiefly important is
however plain enough, viz. that darkness seen through a light medium is
blue.

accettano nè il bianco nè il nero nel numero de' colori."--p. 125, 141.
Elsewhere, however, he sometimes adopts the received opinion.
[23] Leon Battista Alberti, in like manner observes:--"Affermano (i
filosofi) che le spezie de' colori sono sette, cioè, che il bianco ed
il nero sono i duoi estremi, infra i quali ve n'è uno nel mezzo (rosso)
e che infra ciascuno di questi duoi estremi e quel del mezzo, da ogni
parte ve ne sono due altri." An absurd statement of Lomazzo, p. 190,
is copied verbatim from Lodovico Dolce (Somma della Filos. d'Arist.);
but elsewhere, p. 306, Lomazzo agrees with Alberti. Aristotle seems to
have misled the two first, for after saying there are seven colours,
he appears only to mention six: he says--"There are seven colours, if
brown is to be considered equivalent to black, which seems reasonable.
Yellow, again, may be said to be a modification of white. Between these
we find red, purple, green, and blue."--_De Sensu et Sensili_. Perhaps
it is in accordance with this passage that Leonardo da Vinci reckons
eight colours.--_Trattato_, p. 126.
[24] Page 122, 142, 237.
[25] On the authority of this explanation the word μιλάν has sometimes
been translated in the foregoing extracts _obscurity, darkness_.
Raffaello Borghini, in his attempt to describe the doctrine of
Aristotle with a view to painting, observes--"There are two
principles which concur in the production of colour, namely, light
and transparence." But he soon loses this clue to the best part of
the ancient theory, and when he has to speak of the derivation of
colours from white and black, he evidently understands it in a mere
atomic sense, and adds--"I shall not at present pursue the opinion
of Aristotle, who assumes black and white as principal colours, and
considers all the rest as intermediate between them."--_Il Riposo_, 1.
ii. Accordingly, like Lodovico Dolce, he proceeds to a subject where he
was more at home, namely, the symbolical meaning of colours.
[26] This word is only strictly applied to unctuous substances, and may
confirm the views of those writers who have conjectured that asphaltum
was a chief ingredient in the _atramentum_ of the ancients.

"The appearance of white in the centre, according to the Newtonian
theory, arises from each line of rays forming its own spectrum.
These spectra, superposing each other on all the middle part, leave
uncorrected (unneutralised) colours only at the two edges."--S. F.[1]
[1] This was objected to Goethe when his "Beyträge sur Optik" first
appeared; he answered the objection by a coloured diagram in the plates
to the "Farbenlehre:" in this he undertakes to show that the assumed
gradual "correction" of the colours would produce results different
from the actual appearance in nature.
NOTE O.--Par. 252.
These experiments with grey objects, which exhibit different colours
as they are on dark or light grounds, were suggested, Goethe tells
us, by an observation of Antonius Lucas, of Lüttich, one of Newton's
opponents, and, in the opinion of the author, one of the few who made
any well-founded objections. Lucas remarks, that the sun acts merely
as a circumscribed image in the prismatic experiments, and that if the
same sun had a lighter background than itself, the colours of the prism
would be reversed. Thus in Goethe's experiments, when the grey disk is
on a dark ground, it is edged with blue on being magnified; when on a
light ground it is edged with yellow. Goethe acknowledges that Lucas
had in some measure anticipated his own theory.--Vol. ii. p. 440.
NOTE P.--Par. 284.
The earnestness and pertinacity with which Goethe insisted that
the different colours are not subject to different degrees of
refrangibility are at least calculated to prove that he was himself
convinced on the subject, and, however extraordinary it may seem, his
conviction appears to have been the result of infinite experiments
and the fullest ocular evidence. He returns to the question in the
controversial division of his work, in the historical part, and again
in the description of the plates. In the first he endeavours to show
that Newton's experiment with the blue and red paper depends entirely
on the colours being so contrived as to appear elongated or curtailed
by the prismatic borders. "If," he says, "we take a light-blue instead
of a dark one, the illusion (in the latter case) is at once evident.
According to the Newtonian theory the yellow-red (red) is the least
refrangible colour, the violet the most refrangible. Why, then, does
Newton place a blue paper instead of a violet next the red? If the
fact were as he states it, the difference in the refrangibility of
the yellow-red and violet would be greater than in the case of the
yellow-red and blue. But here comes in the circumstance that a violet
paper conceals the prismatic borders less than a dark-blue paper, as
every observer may now easily convince himself," &c.--Polemischer
Theil, par. 45. Desaguliers, in repeating the experiment, confessed
that if the ground of the colours was not black, the effect did
not take place so well. Goethe adds, "not only not so well, but
not at all."--Historischer Theil, p. 459. Lucas of Lüttich, one of
Newton's first opponents, denied that two differently-coloured silks
are different in distinctness when seen in the microscope. Another
experiment proposed by him, to show the unsoundness of the doctrine of
various refrangibility, was the following:--Let a tin plate painted
with the prismatic colours in stripes be placed in an empty cubical
vessel, so that from the spectator's point of view the colours may be
just hidden by the rim. On pouring water into this vessel, all the
colours become visible in the same degree; whereas, it was contended,
if the Newtonian doctrine were true, some colours would be apparent
before others.--Historischer Theil, p. 434.
Such are the arguments and experiments adduced by Goethe on this
subject; they have all probably been answered. In his analysis of
Newton's celebrated _Experimentum Crucis_, he shows again that by
reversing the prismatic colours (refracting a dark instead of a
light object), the colours that are the most refrangible in Newton's
experiment become the least so, and _vice versâ_.
Without reference to this objection, it is now admitted that "the
difference of colour is not a test of difference of refrangibility, and
the conclusion deduced by Newton is no longer admissible as a general
truth, that to the same degree of refrangibility ever belongs the
same colour, and to the same colour ever belongs the same degree of
refrangibility."--Brewster's Optics, p. 72.
NOTE Q--Par. 387.
With the exception of two very inconclusive letters to Sulpice
Boisserée, and some incidental observations in the conclusion of the
historical portion under the head of entoptic colours, Goethe never
returned to the rainbow. Among the plates he gave the diagram of
Antonius de Dominis. An interesting chapter on halos, parhelia, and
paraselenæ, will be found in Brewster's Optics, p. 270.
NOTE R.--Par. 478.
The most complete exhibition of the colouring or mantling of metals
was attained by the late Cav. Nobili, professor of physical science in
Florence. The general mode in which these colours are produced is thus
explained by him:[1]--
"A point of platinum is placed vertically at the distance of about
half a line above a lamina of the same metal laid horizontally at the
bottom of a vessel of glass or porcelain. Into this vessel a solution
of acetate of lead is poured so as to cover not only the lamina of
platinum, but two or three lines of the point as well. Lastly, the
point is put in communication with the negative pole of a battery, and
the lamina with the positive pole. At the moment in which the circuit
is completed a series of coloured rings is produced on the lamina
under the point similar to those observed by Newton in lenses pressed
together."
The scale of colours thus produced corresponds very nearly with that
observed by Newton and others in thin plates and films, but it is
fuller, for it extends to forty-four tints. The following list, as
given by Nobili, is divided by him into four series to agree with
those of Newton: the numbers in brackets are those of Newton's scale.
The Italian terms are untranslated, because the colours in some cases
present very delicate transitions.[2]
_First Series._

"These tints," Professor Nobili observes, "are disposed according to
the order of the thin mantlings which occasion them; the colour of
the thinnest film is numbered 1; then follow in order those produced
by a gradual thickening of the medium. I cannot deceive myself in
this arrangement, for the thin films which produce the colours are
all applied with the same electro-chemical process. The battery, the
solution, the distances, &c., are always the same; the only difference
is the time the effect is suffered to last. This is a mere instant for
the colour of No. 1, a little longer for No. 2, and so on, increasing
for the succeeding numbers. Other criterions, however, are not wanting
to ascertain the place to which each tint belongs."
The scale differs from that of Newton, inasmuch as there is no blue in
Nobili's first series and no green in the second: green only appears in
the third and fourth series. "The first series," says the Professor,
"is remarkable for the fire and metallic appearance of its tints, the
second for clearness and brilliancy, the third and fourth for force and
richness." The fourth, he observes, has the qualities of the third in a
somewhat lesser degree, but the two greens are very nearly alike.
It is to be observed, that red and green are the principal ingredients
in the third and fourth series, blue and yellow in the second and first.

Nobili," Firenze, 1834.
[2] The colours in some of the compound terms are in a manner mutually
neutralising; such terms might, no doubt, be amended.
[3] The three first numbers in Newton's scale are black, blue, and
white.
NOTE S.--Par. 485.
A chapter on entoptic colours, contained in the supplement to Goethe's
works, was translated with the intention of inserting it among the
notes, but on the whole it was thought most advisable to omit it. Like
many other parts of the "Doctrine of Colours" it might have served as
a specimen of what may be achieved by accurate observation unassisted
by a mathematical foundation. The whole theory of the polarization of
light has, however, been so fully investigated since Goethe's time,
that the chapter in question would probably have been found to contain
very little to interest scientific readers, for whom it seems chiefly
to have been intended. One observation occurs in it which indeed has
more reference to the arts; in order to make this intelligible, the
leading experiment must be first described, and for this purpose the
following extracts may serve.
3.[1]
"The experiment, in its simplest form, is to be made as follows:--let
a tolerably thick piece of plate-glass be cut into several squares of
an inch and a half; let these be heated to a red heat and then suddenly
cooled. The squares of glass which do not split in this operation are
now fit to produce the entoptic colours.
4.
"In our mode of exhibiting the phenomenon, the observer is, above all,
to betake himself, with his apparatus to the open air. All dark rooms,
all small apertures (foramina exigua),[2] are again to be given up. A
pure, cloudless sky is the source whence we are derive a satisfactory
insight into the appearances.
5.
"The atmosphere being clear, let the observer lay the squares above
described on a black surface, so placing them that two sides may
be parallel with the plane of vision. When the sun is low, let him
hold the squares so as to reflect to the eye that portion of the sky
opposite to the sun, and he will then perceive four dark points in
the four corners of a light space. If, after this, he turn towards
the quarters of the sky at right angles with that where his first
observation was made, he will see four bright points on a dark ground:
between the two regions the figures appear to fluctuate.
6.
"From this simple reflection we now proceed to another, which, but
little more complicated, exhibits the appearance much more distinctly.
A solid cube of glass, or in its stead a cube composed of several
plates, is placed on a black mirror, or held a little inclined
above it, at sun-rise or sun-set. The reflection of the sky being
now suffered to fall through the cube on the mirror, the appearance
above described will appear more distinctly. The reflection of the
sky opposite to the sun presents four dark points on a light ground;
the two lateral portions of the sky present the contrary appearance,
namely, four light points on a dark ground. The space not occupied by
the corner points appears in the first case as a white cross, in the
other as a black cross, expressions hereafter employed in describing
the phenomena. Before sun-rise or after sun-set, in a very subdued
light, the white cross appears on the side of the sun also.[3]
"We thus conclude that the direct reflection of the sun produces a
light figure, which we call a white cross; the oblique reflection gives
a dark figure, which we call a black cross. If we make the experiment
all round the sky, we shall find that a fluctuation takes place in the
intermediate regions."
We pass over a variety of observations on the modes of exhibiting this
phenomenon, the natural transparent substances which exhibit it best,
and the detail of the colours seen within[4] them, and proceed to an
instance where the author was enabled to distinguish the "direct" from
the "oblique" reflection by means of the entoptic apparatus, in a
painter's study.
40.
"An excellent artist, unfortunately too soon taken from us, Ferdinand
Jagemann, who, with other qualifications, had a fine eye for light and
shade, colour and keeping, had built himself a painting-room for large
as well as small works. The single high window was to the north, facing
the most open sky, and it was thought that all necessary requisites had
been sufficiently attended to.
"But after our friend had worked for some time, it appeared to him,
in painting portraits, that the faces he copied were not equally well
lighted at all hours of the day, and yet his sitters always occupied
the same place, and the serenity of the atmosphere was unaltered.
"The variations of the favourable and unfavourable light had their
periods during the day. Early in the morning the light appeared most
unpleasantly grey and unsatisfactory; it became better, till at last,
about an hour before noon, the objects had acquired a totally different
appearance. Everything presented itself to the eye of the artist in its
greatest perfection, as he would most wish to transfer it to canvas.
In the afternoon this beautiful appearance vanished--the light became
worse, even in the brightest day, without any change having taken place
in the atmosphere.
"As soon as I heard of this circumstance, I at once connected it in
my own mind with the phenomena which I had been so long observing,
and hastened to prove, by a physical experiment, what a clear-sighted
artist had discovered entirely of himself, to his own surprise and
astonishment.
"I had the second[5] entoptic apparatus brought to the spot, and the
effect on this was what might be conjectured from the above statement.
At mid-day, when the artist saw his model best lighted, the north,
direct reflection gave the white cross; in the morning and evening, on
the other hand, when the unfavourable oblique light was so unpleasant
to him, the cube showed the black cross; in the intermediate hours the
state of transition was apparent."
The author proceeds to recall to his memory instances where works of
art had struck him by the beauty of their appearance owing to the light
coming from the quarter opposite the sun, in "direct reflection," and
adds, "Since these decided effects are thus traceable to their cause,
the friends of art, in looking at and exhibiting pictures, may enhance
the enjoyment to themselves and others by attending to a fortunate
reflection."
[1] The numbers, as usual, indicate the corresponding paragraphs in the
original.
[2] In the historical part, Goethe has to speak of so many followers of
Newton who begin their statements with "Si per foramen exiguum," that
the term is a sort of by-word with him.
[3] At mid-day on the 24th of June the author observed the white cross
reflected from every part of the horizon. At a certain distance from
the sun, corresponding, he supposes, with the extent of halos, the
black cross appeared.
[4] Whence the term _entoptic_.
[5] Before described: the author describes several others more or less
complicated, and suggests a portable one. "Such plates, which need
only be an inch and a quarter square, placed on each other to form a
cube, might be set in a brass case, open above and below. At one end of
this case a black mirror with a hinge, acting like a cover, might be
fastened. We recommend this simple apparatus, with which the principal
and original experiment may be readily made. With this we could, in the
longest days, better define the circle round the sun where the black
cross appears," &c.
NOTE T.--Par. 496.
"Since Goethe wrote, all the earths have been decomposed, and have
been shown to be metallic bases united with oxygen; but this does not
invalidate his statement."--S. F.
NOTE U.--Par. 502.
The cold nature of black and its affinity to blue are assumed by the
author throughout; if the quality is opaque, and consequently greyish,
such an affinity is obvious, but in many fine pictures, intense black
seems to be considered as the last effect of heat, and in accompanying
crimson and orange may be said rather to present a difference of
degree than a difference of kind. In looking at the great picture
of the globe, we find this last result produced in climates where
the sun has greatest power, as we find it the immediate effect of
fire. The light parts of black animals are often of a mellow colour;
the spots and stripes on skins and shells are generally surrounded
by a warm hue, and are brown before they are absolutely black. In
combustion, the blackness which announces the complete ignition, is
preceded always by the same mellow, orange colour. The representation
of this process was probably intended by the Greeks in the black and
subdued orange of their vases: indeed, the very colours may have been
first produced in the kiln. But without supposing that they were
retained merely from this accident, the fact that the combination
itself is extremely harmonious, would be sufficient to account for
its adoption. Many of the remarks of Aristotle[1] and Theophrastus[2]
on the production of black, are derived from the observation of the
action of fire, and on one occasion, the former distinctly alludes to
the terracotta kiln. That the above opinion as to the nature of black
was prevalent in the sixteenth century, may be inferred from Lomazzo,
who observes,--"Quanto all' origine e generazione de' colori, la
frigidità è la madre della bianchezza: il calore è padre del nero."[3]
The positive coldness of black may be said to begin when it approaches
grey. When Leonardo da Vinci says that black is most beautiful in
shade, he probably means to define its most intense and transparent
state, when it is furthest removed from grey.

admitted, abounds with absurdities.
NOTE V.--Par. 555.
The nature of vehicles or liquid mediums to combine with the substance
of colours, has been frequently discussed by modern writers on art,
and may perhaps be said to have received as much attention as it
deserves. Reynolds smiles at the notion of our not having materials
equal to those of former times, and indeed, although the methods of
individuals will always differ, there seems no reason to suppose that
any great technical secret has been lost. In these inquiries, however,
which relate merely to the mechanical causes of bright and durable
colouring, the skill of the painter in the adequate employment of the
higher resources of his art is, as if by common consent, left out of
the account, and without departing from this mode of considering the
question, we would merely repeat a conviction before expressed, viz.
that the preservation of internal brightness, a quality compatible with
various methods, has had more to do with the splendour and durability
of finely coloured pictures than any vehicle. The observations that
follow are therefore merely intended to show how far the older
written authorities on this subject agree with the results of modern
investigation, without at all assuming that the old methods, if known,
need be implicitly followed.
On a careful examination of the earlier pictures, it is said that
a resinous substance appears to have been mingled with the colours
together with the oil; that the fracture of the indurated pigment is
shining, and that the surface resists the ordinary solvents.[1] This
admixture of resinous solutions or varnishes with the solid is not
alluded to, as far as we have seen, by any of the writers on Italian
practice, but as the method corresponds with that now prevalent in
England, the above hypothesis is not likely to be objected to for the
present.
Various local circumstances and relations might seem to warrant the
supposition that the Venetian painters used resinous substances. An
important branch of commerce between the mountains of Friuli and Venice
still consists in the turpentine or fir-resin.[2] Similar substances
produced from various trees, and known under the common name of
balsams,[3] were imported from the East through Venice, for general
use, before the American balsams[4] in some degree superseded them;
and a Venetian painter, Marco Boschini, in his description of the
Archipelago, does not omit to speak of the abundance of mastic produced
in the island of Scio.[5]
The testimonies, direct or indirect, against the employment of any
such substances by the Venetian painters, in the solid part of their
work, seem, notwithstanding, very conclusive; we begin with the writer
just named. In his principal composition, a poem[6] describing the
practice and the productions of the Venetian painters, Boschini speaks
of certain colours which they shunned, and adds:--"In like manner
(they avoided) shining liquids and varnishes, which I should rather
call lackers;[7] for the surface of flesh, if natural and unadorned,
assuredly does not shine, nature speaks as to this plainly." After
alluding to the possible alteration of this natural appearance by
means of cosmetics, he continues: "Foreign artists set such great
store by these varnishes, that a shining surface seems to them the
only desirable quality in art. What trash it is they prize! fir-resin,
mastic, and sandarach, and larch-resin (not to say treacle), stuff fit
to polish boots.[8] If those great painters of ours had to represent
armour, a gold vase, a mirror, or anything of the kind, they made it
shine with (simple) colours."[9]
This writer so frequently alludes to the Flemish painters, of whose
great reputation he sometimes seems jealous, that the above strong
expression of opinion may have been pointed at them. On the other hand
it is to be observed that the term _forestieri_, strangers, does not
necessarily mean transalpine foreigners, but includes those Italians
who were not of the Venetian state.[10] The directions given by
Raphael Borghini,[11] and after him by Armenini,[12] respecting the use
and preparation of varnishes made from the very materials in question,
may thus have been comprehended in the censure, especially as some of
these recipes were copied and republished in Venice by Bisagno,[13] in
1642--that is, only six years before Boschini's poem appeared.
Ridolfi's Lives of the Venetian Painters[14] (1648) may be mentioned
with the two last. His only observation respecting the vehicle is, that
Giovanni Bellini, after introducing himself by an artifice into the
painting-room of Antonello da Messina, saw that painter dip his brush
from time to time in linseed oil. This story, related about two hundred
years after the supposed event, is certainly not to be adduced as very
striking evidence in any way.[15]
Among the next writers, in order of time prior to Bisagno, may be
mentioned Canepario[16] (1619). His work, "De Atramentis" contains
a variety of recipes for different purposes: one chapter, _De
atramentis diversicoloribus_, has a more direct reference to painting.
His observations under this head are by no means confined to the
preparation of transparent colours, but he says little on the subject
of varnishes. After describing a mode of preserving white of egg,
he says, "Others are accustomed to mix colours in liquid varnish and
linseed, or nut-oil; for a liquid and oily varnish binds the (different
layers of) colours better together, and thus forms a very fit glazing
material."[17] On the subject of oils he observes, that linseed oil was
in great request among painters; who, however, were of opinion that
nut-oil-excelled it "in giving brilliancy to pictures, in preserving
them better, and in rendering the colours more vivid."[18]
Lomazzo (a Milanese) says nothing on the subject of vehicles in his
principal work, but in his "Idea del Tempio della Pittura,"[19] he
speaks of grinding the colours "in nut-oil, and spike-oil, and other
things," the "and" here evidently means _or_, and by "other things" we
are perhaps to understand other oils, poppy oil, drying oils, &c.
The directions of Raphael Borghini and Vasari[20] cannot certainly be
considered conclusive as to the practice of the Venetians, but they are
very clear on the subject of varnish. These writers may be considered
the earliest Italian authorities who have entered much into practical
methods. In the few observations on the subject of vehicles in Leonardo
da Vinci's treatise, "there is nothing," as M. Merimée observes, "to
show that he was in the habit of mixing varnish with his colours."
Cennini says but little on the subject of oil-painting; Leon Battista
Alberti is theoretical rather than practical, and the published
extracts of Lorenzo Ghiberti's MS. chiefly relate to sculpture.
Borghini and Vasari agree in recommending nut-oil in preference to
linseed-oil; both recommend adding varnish to the colours in painting
on walls in oil, "because the work does not then require to be
varnished afterwards," but in the ordinary modes of painting on panel
or cloth, the varnish is omitted. Borghini expressly says, that oil
alone (senza più) is to be employed; he also recommends a very sparing
use of it.
The treatise of Armenini (1587) was published at Ravenna, and he
himself was of Faenza, so that his authority, again, cannot be
considered decisive as to the Venetian practice. After all, he
recommends the addition of "common varnish" only for the ground or
preparation, as a consolidating medium, for the glazing colours,
and for those dark pigments which are slow in drying. Many of his
directions are copied from the writers last named; the recipes for
varnishes, in particular, are to be found in Borghini. Christoforo
Sorte[21] (1580) briefly alludes to the subject in question. After
speaking of the methods of distemper, he observes that the same colours
may be used in oil, except that instead of mixing them with size, they
are mixed on the palette with nut-oil, or (if slow in drying) with
boiled linseed-oil: he does not mention varnish. The Italian writers
next in order are earlier than Vasari, and may therefore be considered
original, but they are all very concise.
The treatise of Michael Angelo Biondo[22] (1549), remarkable for
its historical mistakes, is not without interest in other respects.
The list of colours he gives is, in all probability, a catalogue of
those in general use in Venice at the period he wrote. With regard
to the vehicle, he merely mentions oil and size as the mediums for
the two distinct methods of oil-painting and distemper, and does not
speak of varnish. The passages in the Dialogue of Doni[23] (1549),
which relate to the subject in question, are to the same effect. "In
colouring in oil," he observes, "the most brilliant colours (that we
see in pictures) are prepared by merely mixing them with the end of a
knife on the palette." Speaking of the perishable nature of works in
oil-painting as compared with sculpture, he says, that the plaster of
Paris (gesso) and mastic, with other ingredients of which the ground
is prepared, are liable to decay, &c.; and elsewhere, in comparing
painting in general with mosaic, that in the former the colours "must
of necessity be mixed with various things, such as oils, gums, white
or yolk of egg, and juice of figs, all which tend to impair the beauty
of the tints." This catalogue of vehicles is derived from all kinds of
painting to enforce the argument, and is by no means to be understood
as belonging to one and the same method.
An interesting little work,[24] still in the form of a dialogue (Fabio
and Lauro), appeared a year earlier; the author, Paolo Pino, was a
Venetian painter. In speaking of the practical methods Fabio observes,
as usual, that oil-painting is of all modes of imitation the most
perfect, but his reasons for this opinion seem to have a reference
to the Venetian practice of going over the work repeatedly. Lauro
asks whether it is not possible to paint in oil on the dry wall, as
Sebastian del Piombo did. Fabio answers, "the work cannot last, for the
solidity of the plaster is impenetrable, and the colours, whether in
oil or distemper, cannot pass the surface." This might seem to warrant
the inference that absorbent grounds were prepared for oil-painting,
but there are proofs enough that resins as well as oil were used with
the _gesso_ to make the preparation compact. See Doni, Armenini, &c.
This writer, again, does not speak of varnish. These appear to be the
chief Venetian and Italian authorities[25] of the sixteenth and part of
the following century; and although Boschini wrote latest, he appears
to have had his information from good sources, and more than once
distinctly quotes Palma Giovane.
In all these instances it will be seen that there is no allusion to the
immixture of varnishes with the solid colours, except in painting on
walls in oil, and that the processes of distemper and oil are always
considered as separate arts.[26] On the other hand, the prohibition
of Boschini cannot be understood to be universal, for it is quite
certain that the Venetians varnished their pictures when done.[27]
After Titian had finished his whole-length portrait of Pope Paul III.
it was placed in the sun to be varnished.[28] Again, in the archives of
the church of S. Niccolo at Treviso a sum is noted (Sept. 21, 1521 ),
"per far la vernise da invernisar la Pala dell' altar grando," and the
same day a second entry appears of a payment to a painter, "per esser
venuto a dar la vernise alla Pala," &c.[29] It is to be observed that
in both these cases the pictures were varnished as soon as done;[30]
the varnish employed was perhaps the thin compound of naphtha (oglio di
sasso) and melted turpentine (oglio d'abezzo), described by Borghini,
and after him by Armenini: the last-named writer remarks that he had
seen this varnish used by the best painters in Lombardy, and had heard
that it was preferred by Correggio. The consequence of this immediate
varnishing may have been that the warm resinous liquid, whatever it
was, became united with the colours, and thus at a future time the
pigment may have acquired a consistency capable of resisting the
ordinary solvents. Not only was the surface of the picture required to
be warm, but the varnish was applied soon after it was taken from the
fire.[31]
Many of the treatises above quoted contain directions for making the
colours dry:[32] some of these recipes, and many in addition, are to be
found in Palomino, who, however defective as an historian,[33] has left
very copious practical details, evidently of ancient date. His drying
recipes are numerous, and although sugar of lead does not appear,
cardenillo (verdigris), which is perhaps as objectionable, is admitted
to be the best of all dryers. It may excite some surprise that the
Spanish painters should have bestowed so much attention on this subject
in a climate like theirs, but the rapidity of their execution must have
often required such an assistance.[34]
One circumstance alluded to by Palomino, in his very minute practical
directions, deserves to be mentioned. After saying what colours should
be preserved in their saucers under water, and what colours should be
merely covered with oiled paper because the water injures them, he
proceeds to communicate "a curious mode of preserving oil-colours," and
of transporting them from place to place. The important secret is to
tie them in bladders, the mode of doing which he enters into with great
minuteness, as if the invention was recent. It is true, Christoforo
Sorte, in describing his practice in water-colour drawing, says he was
in the habit of preserving a certain vegetable green with gum-water in
a bladder; but as the method was obviously new to Palomino, there seems
sufficient reason to believe that oil-colours, when once ground, had,
up to his time, been kept in saucers and preserved under water.[35]
Among the items of expense in the Treviso document before alluded to,
we find "a pan and saucers for the painters."[36] This is in accordance
with Cennini's directions, and the same system appears to have been
followed till after 1700.[37]
The Flemish accounts of the early practice of oil-painting are all
later than Vasari. Van Mander, in correcting the Italian historian in
his dates, still follows his narrative in other respects verbatim. If
Vasari's story is to be accepted as true, it might be inferred that
the Flemish secret consisted in an oil varnish like copal.[38] Vasari
says, that Van Eyck boiled the oils with other ingredients; that the
colours, when mixed with this kind of oil, had a very firm consistence;
that the surface of the pictures so executed had a lustre, so that they
needed no varnish when done; and that the colours were in no danger
from water.[39]
Certain colours, as is well known, if mixed with oil alone, may be
washed off after a considerable time. Leonardo da Vinci remarks, that
verdigris may be thus removed. Carmine, Palomino observes, may be
washed off after six years. It is on this account the Italian writers
recommend the use of varnish with certain colours, and it appears the
Venetians, and perhaps the Italians generally, employed it solely in
such cases. But it is somewhat extraordinary that Vasari should teach
a mode of painting in oil so different in its results (inasmuch as the
work thus required varnish at last) from the Flemish method which he so
much extols--a method which he says the Italians long endeavoured to
find out in vain. If they knew it, it is evident, assuming his account
to be correct, that they did not practice it.
[1] See "Marcucci Saggio Analitico-chimico sopra i colori," &c. Rome,
1816, and "Taylor's Translation of Merimée on Oil-painting," London,
1839. The last-named work contains much useful information.
[2] Italian writers of the 16th century speak of three kinds. Cardanus
says, that of the _abies_ was esteemed most, that of the _larix_ next,
and that of the _picea_ least. The resin extracted by incision from
the last (the pinus abies Linnæi) is known by the name of Burgundy
pitch; when extracted by fire it is black. The three varieties occur
in Italian treatises on art, under the names of _oglio di abezzo_,
_trementina_ and _pece Greca_.
[3] The concrete balsam _benzoe_, called by the Italians _beluzino_,
and _belzoino_, is sometimes spoken of as a varnish.
[4] Marcucci supposes that balsam of copaiba was mixed with the
pigments by the (later) Venetians.

notices of the remains of antiquity in this work would be curious and
important if they could be relied on. In describing the island of
Samos, for instance, the author asserts that the temple of Juno was in
tolerable preservation, and that the statue was still there.

The alliteration of the words _trementina_ and _triaca_ is of course
lost in a translation.
[9] "I li ha fati straluser co' i colori." Boschini was at least
constant in his opinion. In the second edition of his "Ricche Minere
della Pittura Veneziana," which appeared fourteen years after the
publication of his poem, he repeats that the Venetian painters avoided
some colours in flesh "e similmente i lustri e le vernici."
[10] Thus, in the introduction to the "Ricche Minere," Boschini calls
the Milanese, Florentine, Lombard, and Bolognese painters, _forestieri_.

that the books on art were few, and that painters were in the habit of
keeping them secret. He acknowledges that he has availed himself of the
labours of others, but without mentioning his sources: some passages
are copied from Lomazzo. He, however, lays claim to some original
observations, and says he had seen much and discoursed with many
excellent painters.
[14] "Le Meraviglie dell' Arte," Venezia, 1648.
[15] It has been conjectured by some that this story proved the
immixture of varnishes with the colours, and that the oil was only used
to dilute them. The epitaph on Antonello da Messina which existed in
Vasari's time, alludes to his having mixed the colours with oil.

1619. It was republished at Rotterdam in 1718.
[17] "Ita quod magis ex hiis evadit atramentum picturæ summopere
idoneum." Thus, if _atramentum_ is to be understood, as usual, to
mean a glazing colour, the passage can only refer to the immixture of
varnish with the transparent colours applied last in order.
[18] In a passage that follows respecting the mode of extracting
nut-oil, Caneparius appears to mistranslate Galen, c. 7--"De Simplicium
Medicamentorum facultatibus." The observations of Galen on this
subject, and on the drying property of linseed, may have given the
first hint to the inventors of oil-painting. The custom of dating
the origin of this art from Van Eyck is like that of dating the
commencement of modern painting from Cimabue. The improver is often
assumed to be the inventor.

appears, was a native of Verona, had worked in his youth with Giulio
Romano, at Mantua, and communicates the methods taught him by that
painter, for giving the true effects of perspective in compositions
of figures. He is, perhaps, the earliest who describes the process of
water-colour painting as distinguished from distemper and as adapted to
landscape, if the art he describes deserves the name.

[24] "Dialogo di Pittura," Venezia, 1548. Pino, in enumerating the
celebrated contemporary artists, does not include Paul Veronese, for a
very obvious reason, that painter being at the time only about 17 years
of age. Sorte, who wrote thirty years later, mentions "l'eccellente
Messer Paulino nostro," alone.
[25] The Dialogues of Lodovico Dolce, and various other works, are not
referred to here, as they contain nothing on the subject in question.
The latest authority at all connected with the traditions of Venetian
practice, is a certain Giambatista Volpato, of Bassano: he died in
1706, and had been intimate with Ridolfi. The only circumstance he
has transmitted relating to practical details is that Giacomo Bassan,
in retouching on a dry surface, sometimes adopted a method commonly
practised, he says, by Paul Veronese (and commonly practised still),
namely, that of dipping his brush in spirits of turpentine; at other
times he oiled out the surface in the usual manner. Volpato left a MS.
which was announced for publication in Vicenza in 1685, but it never
appeared; it, however, afterwards formed the ground-work of Verci's
"Notizie intorno alla Vita e alle Opere de' Pittori di Bassano."
Venezia, 1775. See also "Lettera di Giambatista Roberti sopra Giacomo
da Ponte," Lugano, 1777. Another MS. by Natale Melchiori, of about the
same date, is preserved at Treviso and Castel Franco: it abounds with
historical mistakes; the author says, for instance, that the Pietro
Martyre was begun by Giorgione and finished by Titian. The recipes for
varnishes and colours are very numerous, but they are mostly copied
from earlier works.
[26] That distemper was not very highly esteemed by the Venetians
may be inferred from the following observation of Pino:--"Il modo di
colorir à guazzo è imperfetto et più fragile et à me non diletta onde
lasciamolo all' oltremontani i quali sono privi della vera via." It is,
however, certain that the Venetians sometimes painted in this style,
and Volpato mentions several works of the kind by Bassan, but he never
hints that he began his oil pictures in distemper.
[27] Boschini says, that the Venetians (he especially means Titian)
rendered their pictures sparkling by finally touching on a dry
surface (_à secco_). The absence of varnish in the solid colours, the
retouching with spirit of turpentine, and even _à secco_, all suppose a
dull surface, which would require varnish. The latter method, alluded
to by Boschini, was an exception to the general practice, and not
likely to be followed on account of its difficulty. Carlo Maratti, on
the authority of Palomino, used to say, "He must be a skilful painter
who can retouch without oiling out."
[28] See a letter by Francesco Bocchi, and another by Vasari, in
the "Lettere Pittoriche" of Bottari. The circumstance is mentioned
incidentally; the point chiefly dwelt on is, that some persons who
passed were deceived, and bowed to the picture, supposing it to be the
pope.
[29] Federici, "Memorie Trevigiane," Venezia, 1803. The altar-piece of
S. Niccolo at Treviso is attributed, in the document alluded to, to
Fra Marco Pensabene, a name unknown; the painting is so excellent as
to have been thought worthy of Sebastian del Piombo: for this opinion,
however, there are no historical grounds. It was begun in 1520, but
before it was quite finished the painter, whoever he was, absconded: it
was therefore completed by another.
[30] Titian's stay in Rome was short, and with respect to the Treviso
altar-piece, a week or two only, at most, can have elapsed between the
completion and the varnishing. Cennini, who recommends delaying a year
at least before varnishing, speaks of pictures in distemper.
[31] See Borghini, Armenini, their Venetian copyist Bisagno, and
Palomino. The last-named writer, though of another school and much
more modern, was evidently well acquainted with the ancient methods:
he says, "Se advierte que siempre que se huviere de barnizar alguna
cosa conviene que la pintura y el barniz estèn calientes."--_El Museo
Pictorico_, v. ii.
[32] Burnt alum, one of the ingredients recommended, might perhaps
account for a shining fracture in the indurated pigment in some old
pictures.
[33] Of the earlier Spanish writers Pacheco may be mentioned next to
Palomino as containing most practical information. Carducho, De Butron,
and others, seldom descend to such details. Palomino contains all the
directions of Pacheco, and many in addition.
[34] See Cean Bermudez, "Sobre la Escuela Sevillana," Cadiz, 1806. The
same reasons induced the later Venetian machinists to paint on dark
grounds, and to make use of (drying) oil in excess. See Zanetti, _Della
Pittura Veneziana_, 1. iv.
[35] Borghini, in describing the method of making a gold-size (the
same as Cennini's), speaks of boiling the "buccie de' colori" in oil;
this only means the skin or pellicle of the colour itself--in fact, he
proceeds to say that they dissolve in boiling. Vasari, in describing
the same process, uses the expression "colori seccaticci."
[36] "Maggio 4 (1520) Per un cadin (catino) per depentori. Per
scudellini per li depentori."--_Mem. Trev._, vol. i. p. 131. Pungileoni
("Memorie Istoriche di Antonio Allegri") quotes a note of expenses
relating to two oil-pictures by Paolo Gianotti; among the items we find
"colori, telari, et brocchette."--vol. ii. p. 75.
[37] Salmon, in his "Polygraphice" (1701), gives the following
direction:--"Oyl colors, if not presently used, will have a skin grow
over them, to prevent which put them into a glass, and put the glass
three or four inches under water," &c.
[38] This varnish appears to have been known some centuries before Van
Eyck's time, but he may have been the first to mix it with the colours.
[39] See Vasari, Life of Antonello da Messina.
NOTE W.--Par. 608.
In the second volume Goethe gives the nomenclature of the Greeks and
Romans at some length. The general notions of the ancients with regard
to colours are thus described:--"The ancients derive all colours from
white and black, from light and darkness. They say, all colours are
between white and black, and are mixed out of these. We must not,
however, suppose that they understand by this a mere atomic mixture,
although they occasionally use the word μίξις;[1] for in the remarkable
passages, where they wish to express a kind of reciprocal (dynamic)
action of the two contrasting principles, they employ the words κρᾶσις,
union, σύγκρισις, combination; thus, again, the mutual influence of
light and darkness, and of colours among each other, is described by
the word κεράννυστας, an expression of similar import.
"The varieties of colours are differently enumerated; some mention
seven, others twelve, but without giving the complete list. From a
consideration of the terminology both of the Greeks and Romans, it
appears that they sometimes employed general for specific terms, and
_vice versâ_.
"Their denominations of colours are not permanently and precisely
defined, but mutable and fluctuating, for they are employed even with
regard to similar colours both on the _plus_ and _minus_ side. Their
yellow, on the one hand, inclines to red, on the other to blue; the
blue is sometimes green, sometimes red; the red is at one time yellow,
at another blue. Pure red (purpur) fluctuates between warm red and
blue, sometimes inclining to scarlet, sometimes to violet.
"Thus the ancients not only seem to have looked upon colour as a
mutable and fleeting quality, but appear to have had a presentiment of
the (physical and chemical) effects of augmentation and re-action. In
speaking of colours they make use of expressions which indicate this
knowledge; they make yellow redden, because its augmentation tends to
red; they make red become yellow, for it often returns thus to its
origin.
"The hues thus specified undergo new modifications. The colours
arrested at a given point are attenuated by a stronger light darkened
by a shadow, nay, deepened and condensed in themselves. For the
gradations which thus arise the name of the species only is often
given, but the more generic terms are also employed. Every colour, of
whatever kind, can, according to the same view, be multiplied into
itself, condensed, enriched, and will in consequence appear more or
less dark. The ancients called colour in this state," &c. Then follow
the designations of general states of colour and those of specific hues.
Another essay on the notions of the ancients respecting the origin
and nature of colour generally, shows how nearly Goethe himself has
followed in the same track. The dilating effect of light objects,
the action and reaction of the retina, the coloured after-image, the
general law of contrast, the effect of semi-transparent mediums in
producing warm or cold colours as they are interposed before a dark or
light background--all this is either distinctly expressed or hinted
at; "but," continues Goethe, "how a single element divides itself into
two, remained a secret for them. They knew the nature of the magnet,
in amber, only as attraction; polarity was not yet distinctly evident
to them. And in very modern times have we not found that scientific
men have still given their almost exclusive attention to attraction,
and considered the immediately excited repulsion only as a mere
after-action?"
An essay on the Painting of the Ancients[2] was contributed by Heinrich
Meyer.

NOTE X.--Par. 670.
This agrees with the general recommendation so often given by high
authorities in art, to avoid a tinted look in the colour of flesh. The
great example of Rubens, whose practice was sometimes an exception
to this, may however show that no rule of art is to be blindly or
exclusively adhered to. Reynolds, nevertheless, in the midst of his
admiration for this great painter, considered the example dangerous,
and more than once expresses himself to this effect, observing on one
occasion that Rubens, like Baroccio, is sometimes open to the criticism
made on an ancient painter, namely, that his figures looked as if they
fed on roses.
Lodovico Dolce, who is supposed to have given the _vivâ voce_ precepts
of Titian in his Dialogue,[1] makes Aretino say: "I would generally
banish from my pictures those vermilion cheeks with coral lips; for
faces thus treated look like masks. Propertius, reproving his Cynthia
for using cosmetics, desires that her complexion might exhibit the
simplicity and purity of colour which is seen in the works of Apelles."
Those who have written on the practice of painting have always
recommended the use of few colours for flesh. Reynolds and others quote
even ancient authorities as recorded by Pliny, and Boschini gives
several descriptions of the method of the Venetians, and particularly
of Titian, to the same effect. "They used," he says, "earths more than
any other colour, and at the utmost only added a little vermilion,
minium, and lake, abhorring as a pestilence _biadetti, gialli santi,
smaltini, verdi-azzurri, giallolini_."[2] Elsewhere he says,[3] "Earths
should be used rather than other colours:" after repeating the above
prohibited list he adds, "I speak of the imitation of flesh, for in
other things every colour is good;" again, "Our great Titian used to
say that he who wishes to be a painter should be acquainted with three
colours, white, black, and red."[4] Assuming this account to be a
little exaggerated, it is still to be observed that the monotony to
which the use of few colours would seem to tend, is prevented by the
nature of the Venetian process, which was sufficiently conformable to
Goethe's doctrine; the gradations being multiplied, and the effect
of the colours heightened by using them as semi-opaque mediums.
Immediately after the passage last quoted we read, "He also gave this
true precept, that to produce a lively colouring in flesh it is not
possible to finish at once."[5] As these particulars may not be known
to all, we add some further abridged extracts explaining the order and
methods of these different operations.
"The Venetian painters," says this writer,[6] "after having drawn in
their subject, got in the masses with very solid colour, without making
use of nature or statues. Their great object in this stage of their
work was to distinguish the advancing and retiring portions, that the
figures might be relieved by means of chiaro-scuro--one of the most
important departments of colour and form, and indeed of invention.
Having decided on their scheme of effect, when this preparation was
dry, they consulted nature and the antique; not servilely, but with the
aid of a few lines on paper (_quattro segni in carta_) they corrected
their figures without any other model. Then returning to their brushes,
they began to paint smartly on this preparation, producing the colour
of flesh." The passage before quoted follows, stating that they used
earths chiefly, that they carefully avoided certain colours, "and
likewise varnishes and whatever produces a shining surface.[7] When
this second painting was dry, they proceeded to scumble over this or
that figure with a low tint to make the one next it come forward,
giving another, at the same time, an additional light--for example, on
a head, a hand, or a foot, thus detaching them, so to speak, from the
canvas." (Tintoret's _Prigionia di S. Rocco_ is here quoted.) "By thus
still multiplying these well-understood retouchings where required, on
the dry surface, _(à secco)_ they reduced the whole to harmony. In this
operation they took care not to cover entire figures, but rather went
on gemming them _(gioielandole)_ with vigorous touches. In the shadows,
too, they infused vigour frequently by glazing with asphaltum, always
leaving great masses in middle-tint, with many darks, in addition to
the partial glazings, and few lights."
The introduction to the subject of Venetian colouring, in the poem by
the same author, is also worth transcribing, but as the style is quaint
and very concise, a translation is necessarily a paraphrase.[8]
"The art of colouring has the imitation of qualities for its object;
not all qualities, but those secondary ones which are appreciable by
the sense of sight. The eye especially sees colours, the imitation
of nature in painting is therefore justly called colouring; but the
painter arrives at his end by indirect means. He gives the varieties
of tone in masses;[9] he smartly impinges lights, he clothes his
preparation with more delicate local hues, he unites, he glazes: thus
everything depends on the method, on the process. For if we look
at colour abstractedly, the most positive may be called the most
beautiful, but if we keep the end of imitation in view, this shallow
conclusion falls to the ground. The refined Venetian manner is very
different from mere direct, sedulous imitation. Every one who has
a good eye may arrive at such results, but to attain the manner of
Paolo, of Bassan, of Palma, Tintoret, or Titian, is a very different
undertaking."[10]
The effects of semi-transparent mediums in some natural productions
seem alluded to in the following passage--"Nature sometimes
accidentally imitates figures in stones and other substances, and
although they are necessarily incomplete in form, yet the principle
of effect (depth) resembles the Venetian practice." In a passage that
follows there appears to be an allusion to the production of the
atmospheric colours by semi-transparent mediums.[11]
[1] "Dialogo della Pittura, intitolato l'Aretino." It was first
published at Venice in 1557; about twenty years before Titian's death.
In the dedication to the senator Loredano, Lodovico Dolce eulogises
the work, which he would hardly have done if it had been entirely his
own: again, the supposition that it may have been suggested by Aretino,
would be equally conclusive, coupled with internal evidence, as to the
original source.
[2] Introduction to the "Ricche Minere della Pittura Veneziana,"
Venezia, 1674. The Italian annotators on older works on painting are
sometimes at a loss to find modern terms equivalent to the obsolete
names of pigments. (See "Antologia dell 'Arte Pittorica.") The colours
now in use corresponding with Boschini's list, are probably yellow
lakes, smalt, verditer, and Naples yellow. Boschini often censures the
practice of other schools, and in this emphatic condemnation he seems
to have had an eye to certain precepts in Lomazzo, and perhaps, even
in Leonardo da Vinci, who, on one occasion, recommends Naples yellow,
lake, and white for flesh. The Venetian writer often speaks, too, in
no measured terms of certain Flemish pictures, probably because they
appeared to him too tinted.
[3] "La Carta del Navegar Pitoresco," p. 338.
[4] Ib. p. 341. In describing Titian's actual practice ("Ricche
Minere"), he, however, adds yellow (ochre). The red is also
particularised, viz., the common terra rossa.
[5] High examples here again prove that the opposite system may attain
results quite as successful.
[6] Introduction to the "Ricche Minere."
[7] See Note to Par. 555. Here again, assuming the description to be
correct, high authorities might be opposed to the Venetians.
[8] The following quatrain may serve as a specimen; the author is
speaking of the importance of the colour of flesh as conducive to
picturesque effect:--
"Importa el nudo; e come ben l'importa!
Un quadro senta nudo è come aponto
Un disnar senza pan, se ben ghe zonto,
Per più delicia, confetura e torta."--p. 346.
In his preface he anticipates, and thus answers the objections to his
Venetian dialect--"Mi, che son Venetian in Venetia e che parlo de'
Pitori Venetiani hò da andarme a stravestir? Guarda el Cielo."
[9] The word _Macchia_, literally a blot, is generally used by Italian
writers, by Vasari for instance, for the local colour. Boschini
understands by it the relative depth of tones rather than the mere
difference of hue. "By macchia," he says, "I understand that treatment
by which the figures are distinguished from each other by different
tones lighter or darker."--_La Carta del Navegar_, p. 328. Elsewhere,
"Colouring (as practised by the Venetians) comprehends both the macchia
and drawing;" (p. 300) that is, comprehends the gradations of light
and dark in objects, and the parts of objects, and consequently, their
essential form. "The macchia," he adds, "is the effect of practice, and
is dictated by the knowledge of what is requisite for effect."
[10]
"Ma l'arivar a la maniera, al trato
(Verbi gratia) de Paulo, del Bassan,
Del Vechio, Tentoreto, e di Tician,
Per Dio, l'è cosa da deventar mato."--p. 294, 297.
[11] The traces of the Aristotelian theory are quite as apparent in
Boschini as in the other Italian writers on art; but as he wrote in the
seventeenth century, his authority in this respect is only important as
an indication of the earlier prevalence of the doctrine.
NOTE Y.--Par. 672.
The author's conclusion here is unsatisfactory, for the colour of
the black races may be considered at least quite as negative as that
of Europeans. It would be safer to say that the white skin is more
beautiful than the black, because it is more capable of indications
of life, and indications of emotion. A degree of light which would
fail to exhibit the finer varieties of form on a dark surface, would
be sufficient to display them on a light one; and the delicate
mantlings of colour, whether the result of action or emotion, are more
perceptible for the same reason.
NOTE Z.--Par. 690.
The author appears to mean that a degree of brightness which the organ
can bear at all, must of necessity be removed from dazzling, white
light. The slightest tinge of colour to this brightness, implies that
it is seen through a medium, and thus, in painting, the lightest,
whitest surface should partake of the quality of depth. Goethe's view
here again accords, it must be admitted, with the practice of the best
colourists, and with the precepts of the highest authorities.--See Note
C.
NOTE A A.--Par. 732.
Ample details respecting the opinions of Louis Bertrand Castel, a
Jesuit, are given in the historical part. The coincidence of some
of his views with those of Goethe is often apparent: he objects,
for instance, to the arbitrary selection of the Newtonian spectrum;
observing that the colours change with every change of distance between
the prism and the recipient surface.--_Farbenl._ vol. ii. p. 527.
Jeremias Friedrich Gülich was a dyer in the neighbourhood of Stutgardt:

Goethe, in his account of Castel, suppresses the learned Jesuit's
attempt at colorific music (the claveçin oculaire), founded on the
Newtonian doctrine. Castel was complimented, perhaps ironically, on
having been the first to remark that there were but three principal
colours. In asserting his claim to the discovery, he admits that there
is nothing new. In fact, the notion of three colours is to be found in
Aristotle; for that philosopher enumerates no more in speaking of the
rainbow,[1] and Seneca calls them by their right names.[2] Compare with
Dante, Parad. c. 33. The relation between colours and sounds is in like
manner adverted to by Aristotle; he says--"It is possible that colours
may stand in relation to each other in the same manner as concords
in music, for the colours which are (to each other) in proportions
corresponding with the musical concords, are those which appear to
be the most agreeable."[3] In the latter part of the 16th century,
Arcimboldo, a Milanese painter, invented a colorific music; an account
of his principles and method will be found in a treatise on painting
which appeared about the same time. "Ammaestrato dal quai ordine Mauro
Cremonese dalla viola, musico dell' Imperadore Ridolfo II. trovò sul
gravicembalo tutte quelle consonanze che dall' Arcimboldo erano segnate
coi colori sopra una carta."[4]
[1] "De Meteor.," lib. 3, c. ii. and iv. He observes that this is the
only effect of colour which painters cannot imitate.
[2] "De Ignib. cœlest." The description of the prism by Seneca is
another instance of the truth of Castel's admission. The Roman
philosopher's words are--"Virgula solet fieri vitrea, stricta vel
pluribus angulis in modo clavæ tortuosæ; hæc si ex transverso solem
accipit colorem talem qualis in arcu videri solet, reddit," &c.

An account of the absurd invention of the same painter in composing
figures of flowers and animals, and even painting portraits in this
way, to the great delight of the emperor, will be found in the same
work.
NOTE C C.--Par. 758.
The moral associations of colours have always been a more favourite
subject with poets than with painters. This is to be traced to the
materials and means of description as distinguished from those of
representation. An image is more distinct for the mind when it is
compared with something that resembles it. An object is more distinct
for the eye when it is compared with something that differs from it.
Association is the auxiliary in the one case, contrast in the other.
The poet, of necessity, succeeds best in conveying the impression
of external things by the aid of analogous rather than of opposite
qualities: so far from losing their effect by this means, the images
gain in distinctness. Comparisons that are utterly false and groundless
never strike us as such if the great end is accomplished of placing
the thing described more vividly before the imagination. In the common
language of laudatory description the colour of flesh is like snow
mixed with vermilion: these are the words used by Aretino in one of
his letters in speaking of a figure of St. John, by Titian. Similar
instances without end might be quoted from poets: even a contrast can
only be strongly conveyed in description by another contrast that
resembles it.[1] On the other hand it would be easy to show that
whenever poets have attempted the painter's method of direct contrast,
the image has failed to be striking, for the mind's eye cannot see the
relation between two colours.
Under the same category of effect produced by association may be
classed the moral qualities in which poets have judiciously taken
refuge when describing visible forms and colours, to avoid competition
with the painters' elements, or rather to attain their end more
completely. But a little examination would show that very pleasing
moral associations may be connected with colours which would be far
from agreeable to the eye. All light, positive colours, light-green,
light-purple, white, are pleasing to the mind's eye, and no degree
of dazzling splendour is offensive. The moment, however, we have to
do with the actual sense of vision, the susceptibility of the eye
itself is to be considered, the law of comparison is reversed, colours
become striking by being opposed to what they are not, and their moral
associations are not owing to the colours themselves, but to the
modifications such colours undergo in consequence of what surrounds
them. This view, so naturally consequent on the principles the author
has himself arrived at, appears to be overlooked in the chapter under
consideration, the remarks in which, in other respects, are acute and
ingenious.

According to the usual acceptation of the term chiaro-scuro in the
artist world, it means not only the mutable effects produced by light
and shade, but also the permanent differences in brightness and
darkness which are owing to the varieties of local colour.
NOTE E E.--Par. 855.
The mannered treatment of light and shade here alluded to by the
author is very seldom to be met with in the works of the colourists;
the taste may have first arisen from the use of plaster-casts, and
was most prevalent in France and Italy in the early part of the last
century. Piazzetta represented it in Venice, Subleyras in Rome. In
France "Restout taught his pupils that a globe ought to be represented
as a polyhedron. Greuze most implicitly adopted the doctrine, and in
practice showed that he considered the round cheeks of a young girl or
an infant as bodies cut into facettes."[1]
[1] See Taylor's translation of Merimée on oil-painting, p. 27.
Barry, in a letter from Paris, speaks of Restout as the only painter
who resembled the earlier French masters: the manner in question is
undoubtedly sometimes very observable in Poussin. The English artist
elsewhere speaks of the "broad, happy manner of Subleyras."--_Works_,
London, 1809.
NOTE F F.--Par. 859.
All this was no doubt suggested by Heinrich Meyer, whose chief
occupation in Rome, at one time, was making sepia drawings from
sculpture (see Goethe's Italiänische Reise). It is hardly necessary to
say that the observation respecting the treatment of the surface in the
antique statues is very fanciful.
NOTE G G.--Par. 863.
This observation might have been suggested by the drawings of Claude,
which, with the slightest means, exhibit an harmonious balance of warm
and cold.
NOTE H H.--Par. 865.
The colouring of Paolo Uccello, according to Vasari's account of him,
was occasionally so remarkable that he might perhaps have been fairly
included among the instances of defective vision given by the author.
His skill in perspective, indicating an eye for gradation, may be also
reckoned among the points of resemblance (see Par. 105).
NOTE I I.--Par. 902.
The quotation before given from Boschini shows that the method
described by the author, and which is true with regard to some of the
Florentine painters, was not practised by the Venetians, for their
first painting was very solid. It agrees, however, with the manner
of Rubens, many of whose works sufficiently corroborate the account
of his process given by Descamps. "In the early state of Rubens's
pictures," says that writer,[1] "everything appeared like a thin wash;
but although he often made use of the ground in producing his tones,
the canvas was entirely covered more or less with colour." In this
system of leaving the shadows transparent from the first, with the
ground shining through them, it would have been obviously destructive
of richness to use white mixed with the darks, the brightness, in
fact, already existed underneath. Hence the well-known precept of
Rubens to avoid white in the shadows, a precept, like many others,
belonging to a particular practice, and involving all the conditions of
that practice.[2] Scarmiglione, whose Aristotelian treatise on colour
was published in Germany when Rubens was three-and-twenty, observes,
"Painters, with consummate art, lock up the bright colours with dark
ones, and, on the other hand, employ white, the poison of a picture,
very sparingly." (Artificiosissimè pictores claros obscuris obsepiant
et contra candido picturarum veneno summè parcentes, &c.)
[1] "La Vie des Peintres Flamands," vol. i.
[2] The method he recommended for keeping the colours pure in the
lights, viz. to place the tints next each other unmixed, and then
slightly to unite them, may have degenerated to a methodical manner
in the hands of his followers. Boschini, who speaks of Rubens himself
with due reverence, and is far from confounding him with his imitators,
contrasts such a system with that of the Venetians, and adds that
Titian used to say, "Chi de imbratar colori teme, imbrata e machia
si medemi."--_Carta del Navegar_, p. 341. The poem of Boschini is in
many respects polemical. He wrote at a time when the Flemish painters,
having adopted and modified the Venetian principles, threatened to
supersede the Italian masters in the opinion of the world. Their
excellence, too, had all the charm of novelty, for in the seventeenth
century Venice produced no remarkable talent, and it was precisely
the age for her to boast of past glories. The contemptuous manner in
which Boschini speaks of the Flemish varnishes, of the fear of mixing
tints, &c., is thus always to be considered with reference to the time
and circumstances. So also his boasting that the Venetian masters
painted without nature, which may be an exaggeration, is pointed at
the _Naturalisti_, Caravaggio and his followers, who copied nature
literally.
NOTE K K.--Par. 903.
The practice here alluded to is more frequently observable in slight
works by Paul Veronese. His ground was often pure white, and in some
of his works it is left as such. Titian's white ground was covered
with a light warm colour, probably at first, and appears to have
been similar to that to which Armenini gives the preference, namely,
"quella che tira al color di carne chiarissima con un non so che di
fiammeggiante."[1]

NOTE L L.--Par. 919.
The notion which the author has here ventured to express may have
been suggested by the remarkable passage in the last canto of Dante's
"Paradiso"--
"Nella profonda e chiara sussistenza,
Dell' alto lume parremi tre giri
Di tre colori e d'una continenza," &c.
After the concluding paragraph the author inserts a letter from a
landscape-painter, Philipp Otto Runge, which is intended to show that
those who imitate nature may arrive at principles analogous to those of
the "Farbenlehre."
