CHAPTER III.

SCIENCE.

Exactly at the era when the great European race was dismembered, the

Latin tongue was disused. This had formerly been the universal tie

between dissimilar tribes, and when it was sundered by such men as

Dantè, who rose to stamp the seal of their genius upon the idiom of

the common people, science soared sublimely amid the new growth of

national languages, and became the supreme and most universally uniting

bond. When Italy had gradually become nationalized as one Italy,

Spain as one Spain, Germany as one Germany, France as one France, and

Britain as one Great Britain; and when that still mightier process of

civilization, the Reformation, had supervened, ecclesiastical union was

destroyed, and then it was that enlarged invention came to the rescue

and supplied the conservative influence which was most in demand.

Increased ardor in the pursuit of knowledge led to wider and more

frequent intercommunications, both mental and physical, while these in

turn were encouraged and protected by the improved polity of aspiring

states. A new voice even more cosmopolitic than cotemporaneous creeds

broke upon the roused and exulting peoples saying, "One is your master,

Thought, and all ye are brethren!" Sciences lead most directly, and

with greatest efficiency to general views; and, above all, natural law,

that science which treats of inherent and universal rights, arose and

was cultivated with propitious zeal. The dawn was begun, and the noon

was not far off when in central Europe a great proficient in universal

history could say: "The barriers are broken, which severed states and

nations in hostile egotism. One cosmopolitic bond unites at present all

thinking minds, and all the light of this century may now freely fall

upon a new Galileo or Erasmus."

From the sixth to the fourteenth century the science of government, as

laid down by Justinian, was illustrated by the labors and comments of

numerous celebrated jurisconsults. The Byzantine legislation yielded on

two essential points to the influence of Christianity. The institution

of marriage, which in the Code and Pandects was only directed by

motives of policy, assumed, in 911, a legal religious character; and

domestic slavery disappeared gradually, to be replaced by serfdom. A

charter was even granted to the serfs by the emperor Emanuel Comnenus

in 1143. Irnerius, at the beginning of the twelfth century, opened the

first law-school in his native city, Bologna, and thenceforth that

science absorbed republican intellects, and led to a clearer defining

of civil rights. A passion for this study possessed even the gentler

sex; as in the case of Novella Andrea da Bologna, who was competent to

fill the professor's chair, during her father's absence, and delivered

eloquent lectures on arid law. Sybil-like, she took care to screen

her lovely face behind a curtain, "lest her beauty should turn those

giddy young heads she was appointed to edify and enlighten." Modeled

after this pattern, law-schools spread widely, and the study of the

Lombard and Tuscan municipal constitutions eventually roused the

European communities to break the bonds of feudalism. The principle of

personal and political freedom so indelibly rooted in each individual

consciousness respecting the equal rights of the whole human race, is

by no means the discovery of recent times. At the darkest hour of the

middle period of history this idea of "humanity" in no mean degree

existed and began to act slowly but continuously in realizing a vast

brotherhood in the midst of our race, a unit impelled by the purpose of

attaining one particular object, namely, the free development of all

the latent powers of man, and the full enjoyment of all his rights.

In this department, as in all the rest, Florence was the seat of

supreme mental power during the age of Leo X.; she fostered the genius

which spread widely in beauty and might. In the fifteenth century, an

ancient and authentic copy of the Justinian constitutions was captured

at Pisa, and given by Lorenzo de Medici to the custody of Politiano,

the most distinguished mediæval professor of legal science. He

corrected numerous manuscripts, supervised the publication of repeated

editions, and prepared the way for all the great improvements which,

in his profession, have since been made. Politiano and Lorenzo, as they

together took daily exercise on horseback, were wont to converse on

their morning studies, and this was characteristic of the intellectual

life of that age and city. The vivifying light which began to pour on a

hemisphere was especially concentrated on the Tuscan capital, and all

the sciences simultaneously awoke from torpor under the invigorating

beams. Like a sheltered garden in the opening of spring, Florence

re-echoed with the earliest sounds of returning energy in every walk of

scientific invention. The absurdities of astrology were exposed, and

legitimate deduction was substituted in the place of conjecture and

fraud. Antonio Squarcialupi excelled all his predecessors in music,

and Francesco Berlinghieri greatly facilitated the study of geography.

Lorenzo de Medici himself gave especial attention to the science of

medicine, and caused the most eminent professors to prosecute their

researches under the auspices of his name and bounty. Paolo Toscanelli

erected his celebrated Gnomen near the Platonic academy; and Lorenzo

da Volpaja constructed for his princely namesake a clock, or piece of

mechanism, which not only marked the hours of the day, but the motions

of the sun and of the planets, the eclipses, the signs of the zodiac,

and the whole revolutions of the heavens.

The study of scientific progress requires us again to notice the

wonderful use which Providence makes of the three original elements

of post-diluvian humanity in the execution of infinite designs. The

Arabians were a Shemitic race, raised into power in near neighborhood

to the heritage of Ham, and were the contributors of numerous

mental stores which were happily adapted yet further to augment the

superiority of Japhet. These children of Ishmael existed at a gloomy

period, and performed a most important work. They drew from the last

living sources of Grecian wisdom, and directed numerous new tributaries

into the great central current of civilization.

Arabia is the most westerly of the three peninsulas of southern Asia,

a position remarkably favorable to political influence and commercial

enterprise. The Mohammedans were an energetic and intelligent people,

whose ancestors led a nomadic life for more than a thousand years;

but from the middle of the ninth century they rose rapidly in the

appreciation and extension of ennobling science. The same race who,

two centuries before, had fearfully ravaged the great conservatory of

learning at Alexandria, themselves became the most ardent admirers of

the muses, and were unequaled proficients in the very studies they had

previously, in their bigoted fury, so nearly annihilated. They garnered

Greek manuscripts with the greatest assiduity, and became sufficiently

masters of their import, to set a proper estimate on these valuable

relics of ancient knowledge.

To the Arabian mathematicians, we are indebted for most valuable

improvements in arithmetic, if not in fact for its invention. They

also transmitted to Europe the knowledge of algebra; and rendered

still more important service to geometrical science, by preserving

many works of the ancients, which, but for them, had been inevitably

lost. The elements of Euclid, with other valuable treatises, were all

transmitted to posterity by their means. The Arabian mathematicians

of the middle ages were the first to apply to trigonometry the method

of calculation which is now generally adopted. Astronomy, optics,

and mechanics were cultivated with no less success; and to the Arabs

especially must be accredited the origin of chemistry, that science

which has been productive of so many invaluable results. This gave them

a better acquaintance with nature than the Greeks or the Romans ever

possessed, and was applied by them most usefully to all the necessary

arts of life. "Alchemy" is an Arabic term, denoting a knowledge of

the substance or composition of a thing. The transmutation of common

metals into gold and silver, and the discovery of a universal medicine,

were futile pursuits; but they led to the method of preparing alcohol,

aqua-fortis, volatile alkali, vitriolic acid, and many other chemical

compounds, which might have remained much longer unknown but for the

persevering labors and patient experiments of the mediæval alchemists.

History records many laudable efforts on the part of the Arabians

in cultivating the natural sciences. Abou-al-Ryan-Byrouny, who died

in the year 941, traveled forty years for the purpose of studying

mineralogy; and his treatise on the knowledge of precious stones, is

a rich collection of facts and observations. Aben-al-Beïthar, who

devoted himself with equal zeal to the study of botany, traversed all

the mountains and plains of Europe, in search of plants. He afterward

explored the burning wastes of Africa, for the purpose of describing

such vegetables as can support the fervid heat of that climate;

and finally passed into the remote countries of Asia. The animals,

vegetables, and fossils common to the three great portions of earth

then known, underwent his personal inspection; and he returned to his

native West loaded with the spoils of the South and East.

Nor were the arts cultivated with less success, or less enriched by the

progress of natural philosophy. A great number of inventions which, at

the present day, add to the comforts of life, are due to the Arabians.

Paper is an Arabic production. It had long, indeed, been made from silk

in China, but Joseph Amrou carried the process of paper-making to his

native city, Mecca, A. D. 649, and caused cotton to be employed in the

manufacture of it first in the year 706. Gunpowder was known to the

Arabians at least a century before it appeared in European history;

and the compass also was known to them in the eleventh century. From

the ninth to the fourteenth century, a brilliant light was spread by

literature and science over the vast countries which had submitted

to the yoke of Islamism. But the boundless regions where that power

once reigned, and still continues supreme, are at present dead to

the interests of science. Deserts of burning sand now drift where

once stood their academies, libraries, and universities; while savage

corsairs spread terror over the seas, once smiling with commerce,

science, and art. Throughout that immense territory, more than twice as

large as Europe, which was formerly subjected to the power of Islamism,

and enriched by its skill, nothing in our day is found but ignorance,

slavery, debauchery and death.

Herein we have a striking illustration of the wonder-working of

Providence. At a time when the nations of Europe were sunk in

comparative barbarism, the Arabians were the depositaries of science

and learning; when the Christian states were in infancy, the fair

flower of Islamism was in full bloom. Nevertheless, the sap of the

Mohammedan civilization was void of that vitality and of those

principles which alone insure eternal progress, therefore was it

requisite that the whole system should be transferred and exhausted on

a more productive field, in order to secure the desired end.

The Arabians were the aggressive conservators of talent rather than

the productive agents of genius; and it must be confessed that they

neither had the presentiment, nor have been direct harbingers of any

of the great inventions which have placed modern society so far above

the ancients. They greatly aggregated and improved the details of

knowledge, but discovered none of the fundamental solutions which have

totally changed the scientific world. At the needful moment, a new

system came suddenly into existence, and spread rapidly from the Indus

to the Tagus, under the victorious crescent. Apparently indigenous

in every clime, its monuments arose in India, along the northern

coast of Africa, and among the Moors in Spain. At Bagdad and Cairo,

Jerusalem and Cordova, Arabian taste and skill flourished in all their

magnificence. It is said that no nation of Asia, Africa, or Europe,

either ancient or modern, has possessed a code of rural regulations

more wise, just, and perfect, than that of the Arabians in Spain;

nor has any nation ever been elevated by the wisdom of its laws, the

intelligence, activity, and industry of its inhabitants, to a higher

pitch of agricultural prosperity. Agriculture was studied by them with

that perfect knowledge of the climate, the soil, and the growth of

plants and animals, which can alone reduce empirical experience into

a science. Nor were the arts cultivated with less success, or less

enriched by the progress of natural philosophy. What remains of so

much glory? Probably not ten persons living are in a situation to take

advantage of the manuscript treasures which are inclosed in the library

of the Escurial. Of the prodigious literary riches of the Arabians,

what still exist are in the hands of their enemies, in the convents of

the monks, or in the royal collections of the West. The instant they

had brought forward all the wealth of the East, and planted it where

by a fruitful amalgamation great and wide benefits could be produced,

then Charles Martel, the _hammer_, heading the progressive progeny

of Japhet, broke down the might of Shem, and repelled his offspring

forever toward the sombre domain and fortunes of Ham.

In this connection, we should consider the use which Providence made

of Feudalism, that great military organization of the middle ages.

It pre-eminently conduced to greater centralization and unity among

civilizing powers. After having destroyed the majesty and influence

of the Germanic and imperial royalty which Pepin and Charlemagne had

revived over the ruins of the Roman world, it rapidly declined and

gave place ultimately to popular liberty. "Feudality," says Guizot,

"has been a first step out of barbarism--the passage from barbarism

to civilization: the most marked character of barbarism is the

independence of the individual--the predominance of individualism; in

this state every man acts as he pleases, at his own risk and peril.

The ascendancy of the individual will and the struggle of individual

forces, such is the great fact of barbarian society. This fact was

limited and opposed by the establishment of the feudal system of

government. The influence alone of territorial and hereditary property

rendered the individual will more fixed and less ordered; barbarism

ceased to be wandering; and was followed by a first step, a surpassing

step toward civilization."

Feudalism engendered new institutions, and they entered deeply into

the spirit of progress. Such were, for example, the Court of Peers

and the Establishments of St. Louis, wherein the first trial was made

toward a uniform legislation for the whole nation. The Crusades form

also a conspicuous feature in the political activity of the Japhetic

nations during the middle ages. The great movement that induced western

Europe to rush to the East had, by no means, the expected results; yet

its consequences became numerous and beneficial. Oppressing Shem was

repulsed in a new direction, and great wealth of science was attained

through his avaricious and violent hands. Thus the turbulent energy of

the military classes, which threatened the progress of civilization,

was exhausted in a distant land; and at the same time the different

races of Europe were made to know each other better, and to banish

all mental hostility, by uniting in one uniform devotion to a lofty

design. Another great consequence of the Crusades was the change of

territorial property, the sale of the estates of the nobles, and their

division among a great number of smaller proprietors. Hence the feudal

aristocracy was weakened, and the lower orders arose with acquired

immunities, ennobled by the spirit of independence, and protected by

municipal laws.

To excel in arms, not in arts, was the ambition of the crusading

knights; and if they gazed for a while with stupid amazement upon the

classic treasures of the East, it was only to calculate the vastness

of their booty, and to collect force for the campaign. Blind frenzy

often characterized the instruments, but infinite wisdom was in the

purpose which governed them. The Crusades contributed to the stability

of governments, the organization of institutions, the cultivation of

arts, the emancipation of thought, and the enlargement of the various

realms of science. Had they not accomplished the needful preparation,

under the guidance of Providence, the influx of literature into Europe

consequent upon the fall of Constantinople would have been worse

than in vain. It was, therefore, wisely ordained that these romantic

expeditions should not be occasions for the acquisition of knowledge

which would transcend the capacities of its agents; but of preparatory

changes fitted to facilitate the adaptation and profitable application

of eastern elements, when, on the vast expanse of the West, the full

time should arrive for them to be completely introduced. The Crusades

tended to confirm and extend pre-existing impressions; to import

rather than to originate knowledge. For any considerable proficiency

in literature or art, unknown to pilgrims in the East, we search in

vain previous to the fifteenth century; but, as we have seen, their

importations of scientific elements were neither few nor small. If the

twelfth and thirteenth centuries were the age of the Crusades, the

following two were not less the age of improvement growing out of the

conflicts in Palestine. They were perpetuated as the popular watchword

of chivalry and theme of romance, till Tasso embodied the thrilling

annals in his immortal poem, which even in his age ceased not to glow

in the common mind. Nor was the fourteenth century in the least a

vacuum between the Crusades and the revival of literature and science;

it was but slightly productive in original material, but its spirit was

permeating, and formed a necessary link between cause and effect, be

the connection however remote. Such is the golden thread which extends

through all the web of passing events, leading on to the accomplishment

of one grand design. In like manner, minstrels formed an integrant

part of the Crusade retinue, by whose happy interposition a more than

imaginary union was formed between martial exploits and poetical

conceptions. Thenceforth the recollection of those enthusiastic

adventures summoned up a train of highly romantic associations, by

which the ideal world was greatly enlarged and peopled with new orders

of captivating creatures, capable of an endless series of fruitful

suggestions. Furthermore, the occupation of the eastern empire was

productive of much advantage to the mental culture of the West.

Persecuted scholars sought refuge and employment beyond the Alps, where

they repaid the hospitality they received with such wisdom as they

possessed.

The Saracenic conquests in Spain brought in vast stores of oriental

knowledge, and frequent intercourse with that land, and with Palestine,

for devotional or commercial purposes, tended greatly to increase

the treasure, and a taste for its enjoyment. But Arabian literature

was a forced plant in Europe, and was as transient in its bloom as

it was unnatural in its maturity. Some traces of a more substantial

cultivation, however, were yet extant within the walls of Bagdad, and

thence the crusaders secured whatever could be advantageously employed.

But the fire of inventive genius, expressed in literary and scientific

research, which once characterized the Arabians, had passed away; the

seeds of preliminary culture had been sown, and their mission ended

with the predestined work of their hands. The arts and sciences of the

Arabians were as unique as their authors; too practical to be elegant,

and too fanciful for ordinary use. To their skill in medicine, and the

exactness of arithmetic, they added the vagueness of the talisman and

horoscope. Astronomy was lost in astrology, chemistry in alchymy, and

medicine in empiricism. But amid the darkness of their errors dwelt

gleams of scientific light superior to any the world had yet seen. The

principal utility lay in the fact that these dim intimations prompted

western Europe to break through habitual associations in matters

of taste and knowledge, and rendered her the instrument of her own

intellectual resuscitation, by exciting an ardor in mental pursuits

hitherto unknown.

The crusades happily exhausted the military spirit of Europe, and

prepared the way for advancement in the arts of peace. This done, the

decline of the feudal system was hastened by the necessity of meeting

the enormous expenses thereby incurred. Many baronial estates were

consequently sold, and thus by degrees were abolished those impediments

which had long been adverse to all the varied forms of culture by

which the afflictions of man are mitigated, or his toils abridged.

The great evil which then required to be abolished had given strength

to a greater good that was to succeed; the commerce which was mainly

created to carry supplies to the crusaders, was ready, on the decline

of martial renown, to go still further in search of a new world, or

to hold mercantile speculations with the remotest regions of the old.

Consequent upon the facilities and refinements of navigation, followed

all those arts of utility and convenience by which the productions

of nature are applied or improved. The arts of weaving and dyeing,

the perfection of paper and the press, as well as gunpowder and the

compass, were the results of quickened industry and enlarged commerce.

All great civilizing powers then attained a simultaneous and distinct

culmination over a new field and under brighter auspices, when each

department of progressive pursuit, the commercial, the literary, and

the military, was furnished, at the fall of the feudal system, with its

own peculiar instrument of invincible conquest.

Bearing in mind that Charles Martel, Peter the Hermit, Richard of the

Lion Heart, and John Sobieski, with their mighty co-agents in the great

preparatory work above described, all arose on the western edge of the

field and age we are now exploring, let us proceed briefly to notice

the still grander developments which followed thereupon.

The westward track on high was determined by the early astronomers of

Egypt. Thales, the father of Greek astronomy, made great advances upon

the speculations he derived from the Egyptians, and expounded them in

his own country. A scholar of his was the first person who pointed out

the obliquity of the circle in which the sun moves among the stars,

and thus "opened the gate of nature." Certainly he who had a clear

view of that path in the celestial sphere, made that first step which

led to all the rest. But when Greek science fell with Ptolemy, there

was apparently no further advance till the rise of Copernicus. During

this interval of thirteen hundred and fifty years, as before stated,

the principal cultivators of astronomical science were the Arabians,

who won their attainments from the Greeks whom they conquered, and

from whom the conquerors of western Europe again received back their

treasure when the love of science and the capacity for its use had

been sufficiently awakened in their minds. In mechanics, also, no

marked advancement was made from Archimedes till the time of Galileo

and Stevinus. The same was true of hydrostatics, the fundamental

problems of which were solved by the same great teacher, whose

principles remained unpursued till the age of Leo X. began to give

perfection to the true Archimedean form of science. As early as Euclid,

mathematicians drew their conclusions respecting light and vision by

the aid of geometry; as, for instance, the convergence of rays which

fall on a concave speculum. But, down to a late period, the learned

maintained that seeing is exercised by rays proceeding from the eye,

not to it; so little was the real truth of optical science understood.

In this respect, as in most others, it was attempted to explain the

kind of causation in which scientific action originates, rather than to

define the laws by which the process is controlled.

In the darkest period of human history, astronomy was the Ararat

of human reason; but it became especially the support and rallying

point of the scientific world, when intellect at large was astir to

investigate the new wonders which rose to view with the effulgent

noon of the middle age. Alphonso, king of Castile, in the year 1252,

corrected the astronomical tables of Ptolemy; and Copernicus, of

Thorn, revived the true solar system, about 1530. Tycho Brahe and

Longomontanus brought forward opposing systems, but which were soon

rejected. Kepler, soon after, gave the first analysis of planetary

motions, and discovered those laws on which rests the theory of

universal gravitation. Galileo advocated the Copernican system; and by

the aid of one of the first telescopes, discovered the satellites of

Jupiter. Hygens discovered Saturn's ring, and fourth satellite; and

four others were soon after noticed by Cassini. Thus was the great

secret of the sidereal universe read, its movements comprehended,

and the glories thereof proclaimed, while emancipated and sublimated

thought, from the loftiest throne of observation began forever to soar

aloft.

As a ray of light became the conductor of mind upward into infinite

space, so a bit of gray stone projected the invisible bridge which

spans from continent to continent, and makes the path over trackless

oceans plain as a broad highway. The properties of this wonderful

mineral were not unknown to the ancients, who, Pliny says, gave the

name "Magnet" to the rock near Magnesia, in Asia Minor; and the poet

Hesiod also makes use of the term "magnet stone." The compass was

employed twelve hundred and fifty years before the time of Ptolemy, in

the construction of the magnetic carriage of the emperor Tsing-wang;

but the Greeks and Romans were completely ignorant of the needle's

pointing toward the north, and never used it for the purpose of

navigation. Before the third crusade, the knowledge of the use of

the compass for land purposes had been obtained from the East, and

by the year 1269 it was common in Europe. But as the time approached

when God would advance, by mightier strides than before, the work of

civilization, he discovered the nations one to another, through the

agency of a tiny instrument, then first made to vibrate on the broadest

sublunary element, and the throne of grandest power. The discovery of

the polarity of the magnet, and the birth of scientific navigation

resulting therefrom, was as simple as it was providential. Some curious

persons were amusing themselves by making swim in a basin of water a

loadstone suspended on a piece of cork. When left at liberty, they

observed it point to the north. The discovery of that fact soon changed

the aspect of the whole world. This invention, which is claimed by the

Neapolitans to have been made by one of their citizens about the year

1302, and by the Venetians as having been introduced by them from the

East, about 1260, led to the discovery of the New World by Columbus

in 1492. When the mariner's compass was needed, it was produced,

and from the most western port of the Old World, mind shot outward

forever! Like the relation between the earth's axis and the auspicious

star which attracts the eye of the wanderer, and shows the North in

the densest wilderness or on the widest waste, so from eternity the

magnetic influence had reference to the business of navigation, and

the true application of this arrived at the destined moment, when, in

connection with correlative events, in like manner prepared, it would

produce the greatest good. After eastern talent had proved the form of

earth, western genius discovered the vastness of oceanic wealth. The

Pillars of Hercules were passed by the great adventurers at sea in the

fifteenth century, and trophies were won richer by far than ever graced

the triumphs of an Alexander on shore. The works of creation were

doubled, and every kingdom forced its treasures upon man's intellect,

along with the strongest inducements to improve recent sciences

as well as ancient literatures, for the widest and most beneficent

practical ends.

The style of working with Providence is, to attain some grand result,

compatibly with ten thousand remote and subordinate interests. One yet

higher and more comprehensive instrumentality was requisite to garner

all the past, ennoble the present, and enrich the future, and at the

fitting moment for its appearance and use, the press stood revealed.

Though the Chinese never carried the art of writing to its legitimate

development in the creation of a perfect phonetic alphabet, they yet

preceded all other nations in the discovery of a mode of rapidly

multiplying writings by means of printing, which was first practiced by

Fung-taou as early as four centuries before its invention in Europe.

Beyond that first step the old East never advanced; there each page

of a book is still printed from an entire block cut for the occasion,

having no idea of the new western system of movable types. What

astrology was to astronomy, alchemy to chemistry, and the search for

the universal panacea to the system of scientific medicine, the crude

process of block-printing was to the perfected press. Engraved wooden

plates were re-invented by Coster, at Harlaem, as early as 1430; but

the great invention of typography is accredited to Guttenberg, who was

assisted by Schoeffer and Faust. This occurred in 1440; and stereotype

printing, from cast metallic plates, is due to Vander-Mey, of Holland,

who first matured it about 1690.

The time had come when men were required to comprehend the ancients,

in order to go beyond them; and at the needful crisis, printing was

given to disseminate all precious originals throughout the world, in

copies innumerable. Had the gift been bestowed at an earlier period, it

would have been disregarded or forgotten, from the want of materials

on which to be employed; and had it been much longer postponed, it is

probable that many works of the highest order, and most desirable to

be multiplied, would have been totally lost. Coincident with this most

conservative invention, was the destruction of the Roman empire in the

East. In the year 1453, Constantinople was captured by the Turks, and

the encouragement which had been shown to literature and science at

Florence, induced many learned Greeks to seek shelter and employment

in that city. Thus, the progressive races were favored with multiplied

facilities for gathering and diffusing those floods of scientific

illumination vouchsafed to deliver from the fantasies that had hitherto

peopled the world--from the prejudices that had held the human mind

in thrall. When Guttenberg raised the first proof-sheet from movable

types, the Mosaic record--"God said, let there be light, and light

was"--flashed upon earth and heaven with unprecedented glory, and that

light of intellect must shoot outward, upward, and abroad forever! It

was not a lucky accident, but the golden fruit of omniscient design, an

invention made with a perfect consciousness of its power and object,

to congregate once isolated inquirers and teachers beneath one temple,

wherein divine aspirations might unite and crown with success all the

scattered and divided efforts for extending the empire of love and

science over the whole civilized earth.

On the banks of the same river Rhine, where printing first attained a

practical use in the hands of a soldier, the discovery of gunpowder was

made by a priest. Its properties were obscurely known long before the

crusades, but are said to have been first traced in their real nature

by Berthold Schwartz, and were made known in 1336, ten years before

cannon appeared in the field of Crecy. Small arms were unknown until

nearly two centuries afterward, and were first used by the Spaniards,

about the year 1521. Fortified with this new power, Cortez, with a

handful of soldiers, was able to conquer the natives of Mexico, the

most civilized and powerful of all the nations then on this western

continent. From the hour when the blundering monk was blown up by his

own experiment, gross physical strength was surrendered to expert

military science; and gunpowder has increasingly exalted intellect in

the conduct of war, not less than in the triumphs of peace.

The history of civilization is written in the triumphs which are won

by scientific invention over the physical laws of nature, and over the

mental infirmities of inferior human tribes. These multiply at points

in space, and periods of time, most happily adapted to promote the

progress and welfare of mankind. The manufacture of glass windows,

chimneys, clocks, paper, the mariner's compass, fire-arms, watches, and

saw-mills, with the process of printing with movable types, and the use

of the telescope, comprise nearly all the inventions of importance

which were made during the lapse of twelve centuries; all the best of

which appeared near the close of the mediæval period, and were not a

little indebted to information obtained from Mohammedans through the

crusades. In the gradual development of human destiny occur flourishing

periods, when numerous men of genius are clustered together with mutual

dependence, and in a narrow space. For instance, Tycho, the founder of

the new measuring system of astronomy, Kepler, Galileo, and Lord Bacon

of Verulam, were cotemporaries; and all of them, except the first,

lived to see the works of Descartes and Fermat. The true celestial

system was discovered by Copernicus in the same year in which Columbus

died, fourteen years after the grandest mundane discovery was made. The

sudden appearance and disappearance of three new stars which occurred

in 1572, 1600, and 1604, excited the wonder of vast assemblies of

people, all over Europe, while humble artizans, in an obscure corner

thereof, were constructing an instrument which should at once calm

their fears and excite the most absorbing astonishment. The telescope

was discovered in Holland, in 1608, and two years after the immortal

Florentine astronomer began to shine prominently above all other

leaders of sublime science. Galileo was the Huss of mediæval progress,

if it be not better to call him the Columbus. The day of predestined

freedom rose over his cradle, and his life-struggle struck the hour.

His hand kindled brighter lamps in the great temple of knowledge, and,

sublime priest of true evangelism as he was, it was fitting that his

place and mission were so central, when he held aloft supremest light.

We love to read the history of his mighty spirit, and contemplate the

serene old man, blinded by gazing at stars, bereaved of his pious

daughter, dragged to the dungeon of the Inquisition, and there visited

by the future secretary of the English Commonwealth. In his own great

maxim, that "we can not teach truth to another, we can only help him to

find it," is contained the germ of all true wisdom, and the foundation

of those future inductions which were to underlie a new age and

revolutionize the world.

Sir Isaac Newton was born the same year Galileo died; and while we

do not forget that Florence was the great centre of science, as of

literature and art during the age of Leo X., let us glance more

particularly at this point to the results which so constantly tended

toward the western extreme.

We have already alluded to many of the developments which illuminated

the night of ignorance, broke the yoke of superstition, gave to doubt

a salutary force, and redoubled the acute delights of scientific

investigation. The wonders of remote hemispheres were simultaneously

unfolded, when Columbus and Vasco de Gama, at one stroke, overthrew

the old geological and geographical systems. Before the close of

the sixteenth century few of the mysteries of nature were left

unvailed, and all that remained for posterity was the work of enlarged

classification, and the perfection of each separate science. The

progress made was, in fact, immense. As the botanic gardens, at that

time planted in the new Italian universities, were fragrant with a

thousand exotics, unknown to antiquity, so the softest fabrics, and

most delicious fruits, recalled to memory the concurrent events of

Providence, which for a long time made Venice and Genoa the emporia

of mediæval traffic. Every luxury of the old world, which commerce

converted into a comfort for the new, is a memento of the discoveries

which guided navigation in the remotest seas, and carried European

adventurers so far as to make the treasures of the entire globe our

own. The science of political economy was also the offspring of that

increased commercial activity which has so much affected the character

of nations as to render new combinations of philosophy necessary for

their direction. We only need allude to the fact that the free cities

of Italy were compelled to yield the leadership in commerce to freer

Holland, and that the sceptre of the seas was finally won by England;

and that the first published theory of political economy was given to

the world in Raleigh's essay, which Quesnoy long after attempted in

vain to refute.

Agriculture was greatly improved in England under the early civilizers

of the Anglo-Norman race. Immediately after the conquest, many thousand

husbandmen, from the fertile plains of Flanders and Normandy, obtained

farms, and employed the same methods of cultivation which had proved

so successful in their native country. The ecclesiastics rivaled the

secular ranks in this noble work. It was so much the custom of the

monks to assist in open fields, especially at seed-time, the hay

season, and harvest, that the famous á Becket, even after he was

Archbishop of Canterbury, used to sally out with the inmates of the

convents, and take part with them in all rural occupations. It was

decreed by the General Council of Lateran, that "all presbyters,

clerks, monks, converts, pilgrims, and peasants, when they are engaged

in the labors of husbandry, shall, together with the cattle in their

plows, and the seed which they carry into the field, enjoy perfect

security; and that all who molest and interrupt them, if they do not

desist when they have been admonished, shall be excommunicated."

Nearly all the finest garden-lands in England were redeemed from the

worst natural condition by the sagacious and industrious Benedictine

religionists. The science they applied in cathedral building is

wonderful to the wisest engineers of our own age, and their taste in

landscape-gardening has ever been the best in the world. Their ruined

abbeys stand in the loveliest positions, and all their great churches,

and colleges, unlike the continental, are encompassed by trees, and

exquisitely decorated grounds. Ingulfus, abbot of Croyland, supplies

an early and characteristic instance of this general disposition.

Richard de Rules, director of Deeping, he tells us, being fond of

agriculture, obtained permission to inclose a large portion of marsh,

for the purpose of separate pasture, excluding the Welland by a strong

dike, upon which he erected a town, and rendered those stagnant fens a

garden of Eden. Others followed their example, and divided the marshes

among them; when some converting them to tillage, some reserving them

for meadow, others leaving them in pasture, found a rich soil for every

purpose.

Evelyn records how four kinds of grapes were early brought from

Italy, with a choice species of white figs, and were naturalized in

his vapory clime. The learned Linacre first brought the damask-rose

from the south; and, at the same time, the royal fruit gardens were

enriched with plums of three different kinds. Edward Grindal, afterward

primate at Canterbury, returning from exile, translated thither the

medicinal plant of the tamarisk. The first oranges were grown by the

Carew family, in Surrey; and the cherry orchards of Kent were commenced

about Sittingbourne. British commerce brought the currant-bush from the

island of Zante, and lettuce from Cos. Cherries came from Cerasuntis,

in Pontus; the peach, from Persia; the chestnut from Castagna, a town

of Magnesia; and the damson plum from Damascus. Lucullus, after the

war with Mithridates, introduced cherries from Pontus into Italy, where

they were rapidly propagated, and, twenty-six years afterward, Pliny

relates, the cherry-tree passed over into Britain. Thus a victory

gained by a Roman consul over a remote antagonist, with whom it would

seem that the western isle could not have the remotest interest, was

the real cause of her being ultimately enriched. Such is the law of

providential dealing, and such are the means and the path it pursues.

In 1609, Shakspeare planted his celebrated mulberry-tree, a production

before almost unknown. Since that epoch, vast treasures of literature,

art, and science have accumulated on that soil, but few new germs have

originated there.

Nearly all the roots of England's maturest science run back into

the deepest mediæval night. A worthy associate with Thomas Aquinas,

Albert the Great, and Michael Scot, was the celebrated Roger Bacon,

a native of Somersetshire, who flourished in the thirteenth century.

This Franciscan monk seems to have been a "Phœnix of intellects" in

the fundamental education of the English race, "an old and new library

of all that was good in science." He greatly established and extended

the natural sciences, by means of mathematics, and the production

of phenomena in the way of experiments. To him especially credit is

due, that the influence which he exercised upon the mode of treating

natural studies, was more beneficial and of more lasting effect than

the discoveries themselves which have been attributed to him. Says

Humboldt, "He roused himself to independent thought, and strongly

blamed the blind trust in the authority of the schools: yet he was so

far from neglecting to search into Grecian antiquity, that he prizes

the study of comparative philology, the application of mathematics,

and the 'Scientia Experimentalis,' to which he devotes a particular

section in his great work. One of the popes, Clement IV., defended and

patronized him; but two others, Nicholas II. and IV., accused him of

magic, and cast him into prison, and thus he experienced the reverses

of fortune which have been felt by great men of all times. He was

acquainted with the Optics of Ptolemæus and the Almagest. As he always

calls Hipparchus 'Abraxis,' like the Arabs, we may conclude that he

had only made use of a Latin translation of the Arabic work. Besides

Bacon's chemical investigations respecting combustible and explosive

mixtures, his theoretical optical works upon Perspective, and the

position of the focus in a concave mirror, are the most important."

It is interesting to contemplate this thoughtful recluse prosecuting

lofty studies in his solitary cell at Oxford. Around him was rising

that greatest of western universities, scarcely one college of which,

according to its historian, Doctor Ingram, can be considered a royal

foundation. Great commoners, architects of their own fortunes, like the

butcher's son, Wolsey, and the poor stone-mason, William of Wykcham,

reared the amplest halls, and educated the mightiest minds. In the

front rank of these great benefactors of science stood Roger Bacon,

greatest of his own age, and projector of nearly all that followed.

His writings contain many curious facts and judicious observations.

From the following statement it would appear that he anticipated his

brother monk on the continent in the discovery of gunpowder: "From

saltpetre and other ingredients," he says, "we are able to form a

fire which will burn to any distance." And again, alluding to its

effects, "a small portion of matter, about the size of the thumb,

properly disposed, will make a tremendous sound and coruscation, by

which cities and armies might be destroyed." One of his biographers

ascribes to him a mechanical contrivance which prepared the way for

the important invention of the air-pump. In his own words, we have the

following anticipations of nearly all the grand inventions which have

more recently changed the condition and aspect of the scientific world:

"I will mention," he says, "things which may be done without the help

of magic, such as indeed magic is unable and incapable of performing;

for a vessel may be so constructed as to make more way with one man

in her, than another vessel well manned. It is possible to make a

chariot which, without any assistance of animals, shall move with the

irresistible force which is ascribed to those scythed chariots in which

the ancients fought. It is possible to make instruments for flying, so

that a man sitting in the middle thereof, and steering with a kind of

rudder, may manage what is contrived to answer the end of wings, so as

to divide and pass through the air. It is no less possible to make a

machine of a very small size, and yet capable of raising or sinking the

greatest weights, which may be of infinite use on certain occasions,

for by the help of such an instrument not above three inches high,

or less, a man may be able to deliver himself and his companions out

of prison, and he and his companions may descend at pleasure. Yea,

instruments may be fabricated by which one man shall draw a thousand

men to him by force and against their will, as also machines which will

enable men to walk without danger at the bottom of seas and rivers."

The above possibilities, as they were suggested in the thirteenth

century, have already in good part been realized, justifying the

prophecies of a man who was before his age, but on the course of its

progress. He beheld the drifting of the great seas of humanity, and

knew not how far they might roll, but he was conscious that forward

they must go. He was the Savonarola of his land and age, the martyr

of science, who possessed his soul in patience, uttered his word, and

waited, knowing that his despised sentence would one day be esteemed

as of the finest gold. Mr. Brande observes, that one of his principal

works "breathes sentiments which would do honor to the most refined

periods of science, and in which many of the advantages likely to be

derived from the mode of investigation insisted upon by his great

successor (Chancellor Bacon) are anticipated." This remark might have

been still more prospective, for the celebrated French experimentalist,

Homberg, availing himself of some hints of chemical combinations

suggested by Roger Bacon, at a much later period, made some important

discoveries in that science.

As soon as printing was perfected on the banks of the Rhine, it was

brought to the banks of the Thames, and, in 1474, the first press in

England was erected by Caxton in Westminster Abbey. Thus the higher

process supervenes upon the inferior which prepared the way, and

supersedes the sources of its own origin and support. In the ancient

Scriptorium of the Abbey, where all literature had been transcribed,

and all science then extant found refuge till more auspicious times,

was carried on an art which was the embodiment of anterior thought, and

the guaranty of a future culture infinitely intensified and enlarged.

As early as 1480, books were printed at St. Albans; and in 1525, there

was a translation of Bœthius printed in the monastery of Tavistock,

by Thomas Richards, monk of the same monastery. That the intercourse

of Caxton with the Abbot of Westminster was on a familiar footing we

learn from his own statement, in 1490: "My Lord Abbott of Westminster

did shew to me late certain evidences written in old English, for to

reduce it to our English now used."

To receive the contributions of the past and reduce them to more

efficient use in the present and for the future, is the mission of

every agent of Providence like Caxton, Roger Bacon, or that gifted

son of St. Albans whose dust lies buried near the venerable Abbey,

where the second press of old England was set at work within the

church, while he thought and wrote without. Francis Bacon was the

complement of Aristotle. Both were adapted to their respective ages,

and were requisite to each other. Had not the great Greek speculated,

the greater Englishman would never have made his demonstrations. The

first developed the general form of all reasoning, and the second

made a specific application of this to the phenomena of matter. But

the deductive mode is only one of the phases of dialectics; and the

Baconians of the present day are much in the same position with regard

to moral science, that the Aristotelians were in with respect to

matter science. A third method was necessitated by the superior worth

of the second, and the nations at large await the man to come who

shall exhaust the whole doctrine of method, and this will doubtless

be consummated in the same direction which scientific excellence has

hitherto pursued.
