partly by the six ancient circles.

IMPERIAL CITIES OR TOWNS, the usual English translation of

_Reichsstädte_, an expression of frequent occurrence in German history.

These were cities and towns subject to no authority except that of the

emperor, or German king, in other words they were immediate; the

earliest of them stood on the demesne land of their sovereign, and they

often grew up around his palaces. A distinction was thus made between a

_Reichsstadt_ and a _Landstadt_, the latter being dependent upon some

prince, not upon the emperor direct. The term _Freie Reichsstadt_, which

is sometimes used in the same sense as _Reichsstadt_, is rightly only

applicable to seven cities, Basel, Strassburg, Spires, Worms, Mainz,

Cologne and Regensburg. Having freed themselves from the domination of

their ecclesiastical lords these called themselves _Freistädte_ and in

practice their position was indistinguishable from that of the

_Reichsstädte_.

In the middle ages many other places won the coveted position of a

_Reichsstadt_. Some gained it by gift and others by purchase; some won

it by force of arms, others usurped it during times of anarchy, while a

number secured it through the extinction of dominant families, like the

Hohenstaufen. There were many more free towns in southern than in

northern Germany, but their number was continually fluctuating, for

their liberties were lost much more quickly than they were gained. Mainz

was conquered and subjected to the archbishop in 1462. Some free towns

fell into the hands of various princes of the Empire and others placed

themselves voluntarily under such protection. Some, like Donauwörth in

1607, were deprived of their privileges by the emperor on account of

real, or supposed, offences, while others were separated from the Empire

by conquest. In 1648 Besançon passed into the possession of Spain, Basel

had already thrown in its lot with the Swiss confederation, while

Strassburg, Colmar, Hagenau and others were seized by Louis XIV.

Meanwhile the free towns had been winning valuable privileges in

addition to those which they already possessed, and the wealthier among

them, like Lübeck and Augsburg, were practically _imperia in imperio_,

waging war and making peace, and ruling their people without any outside

interference. But they had also learned that union is strength. They

formed alliances among themselves, both for offence and for defence, and

these _Städtebünde_ had an important influence on the course of German

history in the 14th and 15th centuries. These leagues were frequently at

war with the ecclesiastical and secular potentates of their district and

in general they were quite able to hold their own in these quarrels. The

right of the free towns to be represented in the imperial diet was

formally recognized in 1489, and about the same time they divided

themselves into two groups, or benches, the Rhenish and the Swabian. By

the peace of Westphalia in 1648 they were formally constituted as the

third college of the diet. A list drawn up in 1422 mentions 75 free

cities, another drawn up in 1521 mentions 84, but at the time of the

French Revolution the number had decreased to 51. At this time the

Rhenish free cities were: Cologne, Aix-la-Chapelle, Lübeck, Worms,

Spires, Frankfort-on-the-Main, Goslar, Bremen, Hamburg, Mühlhausen,

Nordhausen, Dortmund, Friedberg and Wetzlar. The Swabian free cities

were: Regensburg, Augsburg, Nuremberg, Ulm, Esslingen, Reutlingen,

Nördlingen, Rothenburg-on-the-Tauber, Schwäbisch-Hall, Rottweil,

Ueberlingen, Heilbronn, Memmingen, Gmünd, Dinkelsbühl, Lindau, Biberach,

Ravensburg, Schweinfurt, Kempten, Windsheim, Kaufbeuern, Weil, Wangen,

Isny, Pfullendorf, Offenburg, Leutkirch, Wimpfen, Weissenburg, Giengen,

Gengenbach, Zell, Buchorn, Aalen, Buchau and Bopfingen. But a large

proportion of them had as little claim to their exceptional positions as

the pocket boroughs of Great Britain and Ireland had before the passing

of the Reform Bill of 1832.

By the peace of Lunéville in 1801 Cologne, Aix-la-Chapelle, Worms and

Spires were taken by France, and by the decision of the imperial

deputation of 1803 six cities only: Hamburg, Lübeck, Bremen, Augsburg,

Frankfort-on-Main and Nuremberg, were allowed to keep their

_Reichsfreiheit_, or in other words to hold directly of the Empire. This

number was soon further reduced. On the dissolution of the Empire in

1806 Augsburg and Nuremburg passed under the sovereignty of Bavaria, and

Frankfort was made the seat of a duchy for Karl Theodor von Dalberg,

elector and archbishop of Mainz, who was appointed prince primate of the

Confederation of the Rhine. When the German Confederation was

established in 1815 Hamburg, Lübeck, Bremen and Frankfort were

recognized as free cities, and the first three hold that position in the

modern German empire; but Frankfort, in consequence of the part it took

in the war of 1866, lost its independence and was annexed by Prussia.

In the earlier years of their existence the free cities were under the

jurisdiction of an imperial officer, who was called the _Reichsvogt_ or

imperial advocate, or sometimes the _Reichsschultheiss_ or imperial

procurator. As time went on many of the cities purchased the right of

filling these offices with their own nominees; and in several instances

the imperial authority fell practically into desuetude except when it

was stirred into action by peculiar circumstances. The internal

constitution of the free cities was organized after no common model,

although several of them had a constitution drawn up in imitation of

that of Cologne, which was one of the first to assert its independence.

IMPEY, SIR ELIJAH (1732-1809), chief justice of Bengal, was born on the

13th of June 1732, and educated at Westminster with Warren Hastings, who

was his intimate friend throughout life. In 1773 he was appointed the

first chief justice of the new supreme court at Calcutta, and in 1775

presided at the trial of Nuncomar (q.v.) for forgery, with which his

name has been chiefly connected in history. His impeachment was

unsuccessfully attempted in the House of Commons in 1787, and he is

accused by Macaulay of conspiring with Hastings to commit a judicial

murder; but the whole question of the trial of Nuncomar has been

examined in detail by Sir James Fitzjames Stephen, who states that "no

man ever had, or could have, a fairer trial than Nuncomar, and Impey in

particular behaved with absolute fairness and as much indulgence as was

compatible with his duty."

See E. B. Impey, _Sir Elijah Impey_ (1846); and Sir James Stephen,

_The Story of Nuncomar and the Impeachment of Sir Elijah Impey_

(1885).

IMPHAL, the capital of the state of Manipur (q.v.) in eastern Bengal and

Assam, on the north-east frontier of India, situated at the confluence

of three rivers. Pop. (1901) 67,903. It is really only a collection of

villages buried amid trees, with a clearing containing the palace of the

raja, the cantonments, and the houses of the few European residents.

IMPLEMENT (Lat. _implementum_, a filling up, from _implere_, to fill),

in ordinary usage, a tool, especially in the plural for the set of tools

necessary for a particular trade or for completing a particular piece of

work (see TOOLS). It is also the most general term applied to the

weapons and tools that remain of those used by primitive man. The Late

Lat. _implementum_, more usually in the plural, _implementa_, was used

for all the objects necessary to stock or "fill up" a house, farm, &c.;

it was thus applied to furniture of a house, the vestments and sacred

vessels of a church, and to articles of clothing, &c. The transition to

the necessary outfit of a trade, &c., is easy. In its original Latin

sense of "filling up," the term survives in Scots law, meaning full

performance or "fulfilment" of a contract, agreement, &c.; "to

implement" is thus also used in Scots law for to carry out, perform.

IMPLUVIUM, the Latin term for the sunk part of the floor in the atrium

of a Greek or Roman house, which was contrived to receive the water

passing through the compluvium (q.v.) of the roof. The impluvium was

generally in marble and sunk about a foot below the floor of the atrium.

IMPOSITION (from Lat. _imponere_, to place or lay upon), in

ecclesiastical usage, the "laying on" of hands by a bishop at the

services of confirmation and ordination as a sign that some special

spiritual gift is conferred, or that the recipient is set apart for some

special service or work. The word is also used of the levying of a

burdensome or unfair tax or duty, and of a penalty, and hence is applied

to a punishment task given to a schoolboy. From "impose" in the sense of

"to pass off" on some one, imposition means also a trick or deception.

In the printing trade the term is used of the arrangement of pages of

type in the "forme," being one of the stages between composing and

printing.

IMPOST (through the O. Fr. from Lat. _impositum_, a thing laid upon

another; the modern French is _impôt_), a tax or tribute, and

particularly a duty levied on imported or exported merchandise (see

TAXATION, CUSTOMS DUTIES, EXCISE, &c.). In architecture, "impost" (in

German _Kaempfer_) is a term applied in Italian to the doorpost, but in

English restricted to the upper member of the same, from which the arch

springs. This may either be in the same plane as the arch mould or

projecting and forming a plain band or elaborately moulded, in which

case the mouldings are known as impost mouldings. Sometimes the complete

entablature of a smaller order is employed, as in the case of the

Venetian or Palladian window, where the central opening has an arch

resting on the entablature of the pilasters which flank the smaller

window on each side. In Romanesque and Gothic work the capitals with

their abaci take the place of the impost mouldings.

IMPOTENCE (Lat. _impotentia_, want of power), the term used in law for

the inability of a husband or wife to have marital intercourse. In

English matrimonial law if impotence exists in either of the parties to

a marriage at the time of its solemnization the marriage is voidable _ab

initio_. A suit for nullity on the ground of impotence can only be

brought by the party who suffers the injury. Third persons--however

great their interest--cannot sue for a decree on this ground, nor can a

marriage be impeached after the death of one of the parties. The old

rule of the ecclesiastical courts was to require a triennial

cohabitation between the parties prior to the institution of the suit,

but this has been practically abrogated (_G._ v. _G._, 1871, L.R. 2

P.C.D. 287). In suits for nullity on the ground of impotence, medical

evidence as to the condition of the parties is necessary and a

commission of two medical inspectors is usually appointed by the

registrar of the court for the purpose of examining the parties; such

cases are heard _in camera_. In the United States impotence is a ground

for nullity in most states. In Germany it is recognized as a ground for

annulment, but not so in France.

IMPRESSIONISM. The word "Impressionist" has come to have a more general

application in England than in France, where it took currency as the

nickname of a definite group of painters exhibiting together, and was

adopted by themselves during the conflict of opinion which the novelty

of their art excited. The word therefore belongs to the class of

nicknames or battle-names, like "Romanticist," "Naturalist," "Realist,"

which preceded it, words into which the acuteness of controversy infuses

more of theoretical purport than the work of the artists denoted

suggests to later times. The painters included in such a "school" differ

so much among themselves, and so little from their predecessors compared

with the points of likeness, that we may well see in these recurring

effervescences of official and popular distaste rather the shock of

individual force in the artist measured against contemporary mediocrity

than the disturbance of a new doctrine. The "Olympia" of Manet, hooted

at the Salon of 1865 as subversive of all tradition, decency and beauty,

strikes the visitor to the Luxembourg rather as the reversion to a theme

of Titian by an artist of ruder vision than as the demonstration of a

revolutionary in painting. Later developments of the school do appear to

us revolutionary. With this warning in a matter still too near us for

final judgment, we may give some account of the Impressionists proper,

and then turn to the wider significance sometimes given to the name.

The words _Impressioniste_, _Impressionisme_, are said to have arisen

from a phrase in the preface to Manet's catalogue of his pictures

exhibited in 1867 during the Exposition Universelle, from which he was

excluded. "It is the effect," he wrote, "of sincerity to give to a

painter's works a character that makes them resemble a protest, whereas

the painter has only thought of rendering his impression." An

alternative origin is a catalogue in which Claude Monet entitled a

picture of sunrise at sea "Une Impression." The word was probably much

used in the discussions of the group, and was caught up by the critics

as characteristic.[1] At the earlier date the only meaning of the word

was a claim for individual liberty of subject and treatment. So far as

subject went, most, though not all of Manet's pictures were modern and

actual of his Paris, for his power lay in the representation of the

thing before his eye, and not in fanciful invention. His simplicity in

this respect brought him into collision with popular prejudice when, in

the "Déjeuner sur l'herbe" (1863), he painted a modern _fête champêtre_.

The actual characters of his painting at this period, so fancifully

reproached and praised, may be grouped under two heads. (1) The

expression of the object by a few carefully chosen values in flattish

patches. Those patches are placed side by side with little attenuation

of their sharp collision. This simplification of colour and tone recalls

by its broad effects of light and silhouette on the one hand Velasquez,

on the other the extreme simplification made by the Japanese for the

purposes of colour-printing. Manet, like the other painters of his

group, was influenced by these newly-discovered works of art. The image,

thus treated, has remarkable hardiness and vigour, and also great

decorative breadth. Its vivacity and intensity of aspect is gained by

the sacrifice of many minor gradations, and by the judgment with which

the leading values have been determined. This matching of values

produces, technically, a "solid" painting, without glazing or elaborate

transparency in shadows. (2) During this period Manet makes constant

progress towards a fair, clear colour. In his early work the patches of

blond colour are relieved against black shadows; later these shadows

clear up, and in place of an indeterminate brown sauce we find shadows

that are colours. A typical picture of this period is the "Musique aux

Tuileries," refused by the Salon of 1863. In this we have an actual

out-of-doors scene rendered with a frankness and sharp taste of

contemporary life surprising to contemporaries, with an elision of

detail in the treatment of a crowd and a seizing on the chief colour

note and patch that characterize each figure equally surprising, an

effort finally to render the total high-pitched gaiety of the spectacle

as a banquet of sunlight and colour rather than a collection of separate

dramatic groups.

For life of Édouard Manet (1832-1883) see Edmond Bazire, _Manet_

(Paris, 1884). An idea of the state of popular feeling may be gained

by reading Zola's eloquent defence in _Mon Salon_, which appeared in

_L'Événement_ (1866) and _Édouard Manet_ (1867), both reprinted in

_Mes Haines_ (Paris, 1880). The same author has embodied many of the

impressionist ideals in Claude Lantier, the fictitious hero of

_L'Oeuvre_. Other writers belonging to Manet's group are Théodore

Duret, author of _Les Peintres français en 1867_ and _Critique

d'avant-garde_, articles and catalogue-prefaces reprinted 1885. See

also, for Manet and others, J. K. Huysman's _L'Art moderne_ (1883) and

_Certains_. Summaries of the literature of the whole period will be

found in R. Muther, _The History of Modern Painting_ (tr. London,

1896), not always trustworthy in detail, and Miss R. G. Kingsley, _A

History of French Art_ (1899). For an interesting critical account see

W. C. Brownell, _French Art_ (1892).

The second period, to which the name is sometimes limited, is

complicated by the emergence of new figures, and it is difficult as yet,

and perhaps will always remain difficult, to say how much of originality

belongs to each artist in the group. The main features are an intenser

study of illumination, a greater variety of illuminations, and a

revolution in _facture_ with a view to pressing closer to a high pitch

of light. Manet plays his part in this development, but we shall not be

wrong probably in giving to Claude Monet (b. 1840) the chief rôle as the

instinctive artist of the period, and to Camille Pissarro (b. 1830) a

very large part as a painter, curious in theory and experiment. Monet at

the early date of 1866 had painted a picture as daring in its naïve

brutality of out-of-door illumination as the "Déjeuner sur l'herbe." But

this picture has the breadth of patch, solidity and suavity of paste of

Manet's practice. During the siege of Paris (1870-71) Monet and Pissarro

were in London, and there the study of Turner's pictures enlarged their

ideas of the pitch in lighting and range of effect possible in painting,

and also suggested a new handling of colour, by small broken touches in

place of the large flowing touches characteristic of Manet. This method

of painting occupied much of the discussion of the group that centred

round Manet at the Café Guerbois, in the Batignolles quarter (hence

called _L'École de Balignolles_). The ideas were: (1) Abolition of

conventional brown tonality. But all browns, in the fervour of this

revolt, went the way of conventional brown, and all ready-made mixtures

like the umbers, ochres, siennas were banished from the palette. Black

itself was condemned. (2) The idea of the spectrum, as exhibiting the

series of "primary" or "pure" colours, directed the reformed palette.

Six colours, besides white, were admitted to represent the chief hues of

the spectrum. (3) These colours were laid on the canvas with as little

previous mixture on the palette as possible to maintain a maximum of

luminosity, and were fused by touch on the canvas as little as possible,

for the same reason. Hence the "broken" character of the touch in this

painting, and the subordination of delicacies of form and suave

continuity of texture to the one aim of glittering light-and-colour

notation. Justification of these procedures was sought in occasional

features of the practice of E. Delacroix, of Watteau, of J. B. Chardin,

in the hatchings of pastel, the stipple of water-colour. With the

ferment of theory went a _parti pris_ for translating all effects into

the upper registers of tone (cf. Ruskin's chapter on Turner's practice

in _Modern Painters_), and for emphasizing the colour of shadows at the

expense of their tone. The characteristic work of this period is

landscape, as the subject of illumination strictly observed and followed

through the round of the day and of the seasons. Other pictorial motives

were subordinated to this research of effect, and Monet, with a

haystack, group of poplars, or church front, has demonstrated the

variety of lighting that the day and the season bring to a single scene.

Besides Pissarro, Alfred Sisley (1840-1899) is a member of the group,

and Manet continues his progress, influenced by the new ideas in

pictures like "Le Linge" and "Chez le Père Lathuille."

Edmond Degas (b. 1834), a severe and learned draughtsman, is associated

with this landscape group by his curiosity in the expression of

momentary action and the effects of artificial illumination, and by his

experiments in broken colour, more particularly in pastel. The novelty

of his matter, taken from unexplored corners of modern life, still more

the daring and irony of his observation and points of view, and the

strangeness of his composition, strongly influenced by Japanese art,

enriched the associations now gathering about the word "impressionist."

Another name, that of Auguste Renoir (b. 1841), completes the leading

figures of the group. Any "school" programme would be strained to

breaking-point to admit this painter, unless on the very general grounds

of love of bright colour, sunlit places and independence of vision. He

has no science of drawing or of tone, but wins a precarious charm of

colour and expression.

The landscape, out-of-doors line, which unites in this period with

Manet's line, may be represented by these names: J. B. Corot, J. B.

Jongkind, Boudin, Monet. Monet's real teacher was Eugène Boudin

(1824-1898), (See Gustave Cahen's _Eugène Boudin_, Paris, 1900). They,

and others of the group, worked together in a painters' colony at

Saint Simeon, near Honfleur. It is usual to date the origin of

_plein-air_ painting, i.e. painting out-of-doors, in an out-of-doors

key of tone, from a picture Manet painted in the garden of de Nittis,

just before the outbreak of war in 1870. This dates only Manet's

change to the lighter key and looser handling. It was Monet who

carried the practice to a logical extreme, working on his canvas only

during the effect and in its presence. The method of Degas is

altogether different, viz., a combination in the studio from

innumerable notes and observations. It will be evident from what has

been said above that impressionistic painting is an artistic ferment,

corresponding to the scientific research into the principles of light

and colour, just as earlier movements in painting coincided with the

scientific study of perspective and anatomy. Chevreul's famous book,

already referred to, _De la loi du contraste simultané des couleurs_

(1838), established certain laws of interaction for colours adjacent

to one another. He still, however, referred the sensations of colour

to the three impossible "primaries" of Brewster--red, blue and yellow.

The Young-Helmholtz theory affected the palette of the Impressionists,

and the work of Ogden Rood, _Colour_ (Internat. Scientific Series,

1879-1881), published in English, French and German, furnished the

theorists with formulae measuring the degradation of pitch suffered by

pigments in mixture.

The Impressionist group (with the exception of Manet, who still fought

for his place in the Salon) exhibited together for the first time as

L'Exposition des Impressionistes at Nadar's, Boulevard des Capucines,

in 1874. They were then taken up by the dealer Durand-Ruel, and the

succeeding exhibitions in 1876, 1877, 1879, 1880, 1881, 1882 and 1886

were held by him in various galleries. The full history of these

exhibitions, with the names of the painters, will be found in two

works: Félix-Fénéon, _Les Impressionistes en 1886_ (Paris, 1886), and

G. Geffroy, _La Vie artistique_ ("Histoire de l'impressionisme," in

vol. for 1894). See also G. Lecomte, _L'Art impressionists d'après la

collection privée de M. Durand-Ruel_ (Paris, 1892); Duranty, _La

Peinture nouvelle_ (1876). Besides the names already cited, some

others may be added: Madame Berthe Morisot, sister-in-law of Manet;

Paul Cézanne, belonging to the Manet-Pissarro group; and, later,

Gauguin. J. F. Raffaëlli applied a "characteristic" drawing, to use

his word, to scenes in the dismal suburbs of Paris; Forain, the

satiric draughtsman, was a disciple of Degas, as also Zandomeneghi.

Miss Mary Cassatt was his pupil. Caillebotte, who bequeathed the

collection of Impressionist paintings now in the Luxembourg, was also

an exhibitor; and Boudin, who linked the movement to the earlier

schools.

The first exhibitions of the Impressionists in London were in 1882 and

1883, but their fortunes there cannot be pursued in the present

article, nor the history of the movement beyond its originators. This

excludes notable figures, of which M. Besnard may be chosen as a type.

In Manet's painting, even in the final steps he took towards "la

peinture claire," there is nothing of the "decomposition of tones" that

logically followed from the theories of his followers. He recognized the

existence in certain illuminations of the violet shadow, and he adopted

in open-air work a looser and more broken touch. The nature of his

subjects encouraged such a handling, for the painter who attempts to

note from nature the colour values of an elusive effect must treat form

in a summary fashion, still more so when the material is in constant

movement like water. Moreover, in the river-side subjects near Paris

there was a great deal that was only pictorially tolerable when its tone

was subtracted from the details of its form. Monet's painting carries

the shorthand of form and broken colour to extremity; the flowing touch

of Manet is chopped up into harsher, smaller notes of tone, and the

pitch pushed up till all values approach the iridescent end of the

register. It was in 1886 that the _doctrinaire_ ferment came to a head,

and what was supposed to be a scientific method of colour was

formulated. This was _pointillisme_, the resolution of the colours of

nature back into six bands of the rainbow or spectrum, and their

representation on the canvas by _dots_ of unmixed pigment. These dots,

at a sufficient distance, combine their hues in the eye with the effect

of a mixture of coloured _lights_, not of pigments, so that the result

is an increase instead of a loss of luminosity. There are several

fallacies, however, theoretical and practical, in this "spectral

palette" and pointillist method. If we depart from the three primaries

of the Helmholtz hypothesis, there is no reason why we should stop at

six hues instead of six hundred. But pigments follow the spectrum series

so imperfectly that the three primaries, even if we could exactly locate

them, limit the palette considerably in its upper range. The sacrifice

of black is quite illogical, and the lower ranges suffer accordingly.

Moreover, it is doubtful whether many painters have followed the laws of

mixture of lights in their dotting, e.g. dotting green and red together

to produce yellow. It may be added that dotting with oil pigment is in

practice too coarse and inaccurate a method. This innovation of

_pointillisme_ is generally ascribed to George Seurat (d. 1890), whose

picture, "La Grande Jatte," was exhibited at the Rue Laffitte in 1886.

Pissarro experimented in the new method, but abandoned it, and other

names among the _Pointillistes_ are Paul Signac, Vincent van Gogh, and

van Rysselberghe. The theory opened the way for endless casuistries, and

its extravagances died out in the later exhibition of the _Indépendants_

or were domesticated in the Salon by painters like M. Henri Martin.

The first modern painter to concern himself scientifically with the

reactions of complementary colours appears to have been Delacroix (J.

Leonardo, it should be remembered, left some notes on the subject). It

is claimed for Delacroix that as early as 1825 he observed and made

use of these reactions, anticipating the complete exposition of

Chevreul. He certainly studied the treatise, and his biographers

describe a dial-face he constructed for reference. He had quantities

of little wafers of each colour, with which he tried colour effects, a

curious anticipation of pointillist technique. The pointillists claim

him as their grandfather. See Paul Signac, "D'Eugène Delacroix au

Néo-Impressionnisme" (_Revue Blanche_, 1898). For a fuller discussion

of the spectral palette see the _Saturday Review_, 2nd, 9th and 23rd

February and 23rd March 1901.

In England the ideas connected with the word Impressionism have been

refracted through the circumstances of the British schools. The

questions of pitch of light and iridescent colour had already arisen

over the work of Turner, of the Pre-Raphaelites, and also of G. F.

Watts, but less isolated and narrowed, because the art of none of these

limited itself to the pursuit of light. _Pointillisme_, after a fashion,

existed in British water-colour practice. But the Pre-Raphaelite school

had accustomed the English eye to extreme definition in painting and to

elaboration of detail, and it happened that the painting of James

M'Neill Whistler (Grosvenor Gallery, 1878) brought the battle-name

Impressionism into England and gave it a different colour. Whistler's

method of painting was in no way revolutionary, and he preferred to

transpose values into a lower key rather than compete with natural

pitch, but his vision, like that of Manet under the same influences,

Spanish and Japanese, simplified tone and subordinated detail. These

characteristics raised the whole question of _the science and art of

aspect in modern painting_, and the field of controversy was extended

backwards to Velasquez as the chief master of the moderns.

"Impressionism" at first had meant individualism of vision, later the

notation of fugitive aspects of light and of movement; now it came to

mean breadth in pictorial vision, all the simplifications that arise

from the modern analysis of aspect, and especially the effect produced

upon the parts of a picture-field by attending to _the impression of the

whole_. Ancient painting analyses aspect into three separate acts as

form, tone and colour. All forms are made out with equal clearness by a

conventional outline; over this system of outlines a second system of

light and shade is passed, and over this again a system of colours. Tone

is conceived as a difference of black or white added to the tints, and

the colours are the definite local tints of the objects (a blue, a red,

a yellow, and so forth). In fully developed modern painting, instead of

an object analysed into sharp outlines covered with a uniform colour

darkened or lightened in places, we find an object analysed into a

number of surfaces or planes set at different angles. On each of these

facets the character of the object and of the illumination, with

accidents of reflection, produces a patch called by modern painters a

"value," because it is colour of a particular value or tone. (With each

difference of tone, "value" implies a difference of hue also, so that

when we speak of a different tone of the same colour we are using the

word "same" in a loose or approximate sense.) These planes or facets

define themselves one against another with greater or less sharpness.

Modern technique follows this modern analysis of vision, and in one act

instead of three renders by a "touch" of paint the shape and value of

these facets, and instead of imposing a uniform ideal outline at all

their junctions, allows these patches to define themselves against one

another with variable sharpness.

Blurred definition, then, as it exists in our natural view of things, is

admitted into painting; a blurring that may arise from distance, from

vapour or smoke, from brilliant light, from obscurity, or simply from

the nearness in value of adjacent objects. Similarly, much detail that

in primitive art is elaborated is absorbed by rendering the aspect

instead of the facts known to make up that aspect. Thus hair and fur,

the texture of stuffs, the blades of grass at a little distance, become

patches of tone showing only their larger constructive markings. But the

blurring of definitions and the elimination of detail that we find in

modern pictorial art are not all of this ready-made character. We have

so far only the scientific analysis of a field of view. If the painter

were a scientific reporter he would have to pursue the systems of

planes, with their shapes and values, to infinity. Impressionism is the

art that surveys the field and determines which of the shapes and tones

are of chief importance to the _interested_ eye, enforces these, and

sacrifices the rest. Construction, the logic of the object rendered,

determines partly this action of the eye, and also decoration, the

effects of rhythm in line and harmony in fields of colour. These motives

belong to all art, but the specially impressionist motive is the act of

_attention_ as it affects the aspect of the field. We are familiar, in

the ordinary use of the eye, with two features of its structure that

limit clearness of vision. There is, first, the spot of clear vision on

the retina, outside of which all falls away into blur; there is,

secondly, the action of _focus_. As the former limits clear definition

to one spot in the field extended vertically and laterally, so focus

limits clear definition to one plane in the third dimension, viz. depth.

If three objects, A, B and C, stand at different depths before the eye,

we can at will fix A, whereupon B and C must fall out of focus, or B,

whereupon A and C must be blurred, or C, sacrificing the clearness of A

and B. All this apparatus makes it impossible to see everything at once

with equal clearness, enables us, and forces us for the uses of real

life, to frame and limit our picture, according to the immediate

interest of the eye, whatever it may be. The painter instinctively uses

these means to arrive at the emphasis and neglect that his choice

requires. If he is engaged on a face he will now screw his attention to

a part and now relax it, distributing the attention over the whole so as

to restore the bigger relations of aspect. Sir Joshua Reynolds describes

this process as seeing the whole "with the dilated eye"; the commoner

precept of the studios is "to look with the eyes half closed"; a third

way is to throw the whole voluntarily out of focus. In any case the

result is that minor planes are swamped in bigger, that smaller patches

of colour are swept up into broader, that markings are blurred. The

final result of these tentative reviews records, in what is blurred and

what is clear, the attention that has been distributed to different

parts, and to parts measured against the whole. The Impressionist

painter does not allot so much detail to a face in a full-length

portrait as to a head alone, nor to twenty figures on a canvas as to

one. Again, he indicates by his treatment of planes and definitions

whether the main subject of his picture is in the foreground or the

distance. He persuades the eye to slip over hosts of near objects so

that, as in life, it may hit a distant target, or concentrate its attack

on what is near, while the distance falls away into a dim curtain. All

those devices by which attention is directed and distributed, and the

importance in space of an object established, affect impressionistic

composition.

It is an inevitable misunderstanding of painting which plays the game of

art so closely up to the real aspects of nature that its aim is that of

mere exact copying. Painting like Manet's, accused of being realistic in

this sense, sufficiently disproves the accusation when examined. Never

did painting show a _parti pris_ more pronounced, even more violent. The

elisions and assertions by which Manet selects what he finds significant

and beautiful in the complete natural image are startling to the stupid

realist, and the Impressionist may best be described as the painter who

out of the completed contents of vision constructs an image moulded upon

his own interest in the thing seen and not on that of any imaginary

schoolmaster. Accepting the most complex terms of nature with their

special emotions, he uses the same freedom of sacrifice as the man who

at the other end of the scale expresses his interest in things by a few

scratches of outline. The perpetual enemy of both is the eclectic, who

works for possible interests not his own.

Some of the points touched on above will be found amplified in

articles by the writer in _The Albemarle_ (September 1892), the

_Fortnightly Review_ (June 1894), and _The Artist_ (March-July 1896).

An admirable exposition of Impressionism in this sense is R. A. M.

Stevenson's _The Art of Velasquez_ (1895). Mr Stevenson was trained in

the school of Carolus Duran, where impressionist painting was reduced

to a system. Mr Sargent's painting is a brilliant example of the

system. (D. S. M.)
