Chapter 6

"The beauty of the Roman buildings requires a skillful overseer, in order that such a wonderful forest of edifices should be preserved with constant care, and the new ones properly constructed, both internally and externally. Therefore we direct our generosity not only to the preservation of ancient things, but to the investing the new ones with the glories of antiquity. Be it known, therefore, to your illustrious person, that for this end an architect of the Roman walls is appointed. And because the study of the arts requires assistance, we desire that he may have every reasonable accommodation that his predecessors have enjoyed. He will certainly see things superior to what he has read of, and more beautiful than he could ever have imagined. The statues still feel their renowned authors, and appear to live: he will observe expressed in the bronze, the veins, the muscles swollen by exertion, the nerves gradually stretched, and the figure expressing those feelings which act on a living subject.

"It is said that the first artists in Italy were the Etruscans, and thus posterity has given to them, as well as to Rome, almost the power of creating man. How wonderful are the horses, so full of spirit, with their fiery nostrils, their sparkling eyes, their easy and graceful limbs;--they would move, if not of metal. And what shall we say of those lofty, slender, and finely fluted columns, which appear a part of the sublime structure they support? That appears wax, which is hard and elegant metal; the joints in the marble being like natural veins. The beauty of art is to deceive the eye. Ancient historians acquaint us with only seven wonders in the world: the Temple of Diana, at Ephesus; the magnificent sepulchre of the king Mausolus, from whence is derived the word mausoleum; the bronze Colossus of the Sun, in Rhodes; the statue of Jupiter Olympius, of gold and ivory, formed by the masterly hand of Phidias, the first of architects; the palace of Cyrus, King of Media, built by Memnon of stones united by gold; the walls of Babylon, constructed by Semiramis of brick, pitch, and iron; the pyramids of Egypt, the shadows of which do not extend beyond the space of their construction. But who can any longer consider these as wonders, after having seen so many in Rome? Those were famous because they preceded us; it is natural that the new productions of the then barbarous ages should be renowned. It may truly be said that all Rome is wonderful. We have therefore selected a man clever in the arts, who, in seeing so many ingenious things of antiquity, instead of remaining merely enchanted with them, has set himself to work to investigate the reason, study their books, and instruct himself, that he may become as learned as those in the place of whom he is to consider himself appointed."

Milizia says of Theodoric, "Is this the language of a Gothic barbarian, the destroyer of good taste? Pericles, Alexander, Adrian, or one of the Medici could not have reasoned better." And again, "Can these Goths be the inventors of that architecture vulgarly called Gothic? and are these the barbarians said to have been the destroyers of the beautiful monuments of antiquity? Ecclesiastical history gives to the good Christians and the jealous ecclesiastics the honor of having dismantled temples, and disfigured statues in Italy, Greece, Asia, and Egypt. * * * It is clear that the Goths were not the authors of that architecture called Gothic. The Goths and barbarians who overran Italy had not any characteristic architecture, good or bad. They brought with them neither architects, painters, nor poets. They were all soldiers, and when fixed in Italy employed Italian artists; but as in that country, good taste was much on the decline, it now became more debased, notwithstanding the efforts made by the Goths to revive it."

ARCHIMEDES.

This wonderful genius was of royal descent, and born at Syracuse about B.C. 287. He was a relative of king Hiero, who held him in the highest esteem and favor, though he does not appear to have held any public office, preferring to devote himself entirely to science. Such was his enthusiasm, that he appears at times to have been so completely absorbed in contemplation and calculations, as to be totally unconscious of what was passing around him. We cannot fully estimate his services to mathematics, for want of an acquaintance with the previous state of science; still we know that he enriched it with discoveries of the highest importance, upon which the moderns have founded their admeasurements of curvilinear surfaces and solids. Euclid, in his elements, considers only the relations of some of these magnitudes to each other, but does not compare them with surfaces and solids bounded by straight lines. Archimedes developed the proportions necessary for effecting this comparison, in his treatises on the sphere and cylinder, the spheroid and conoid, and in his work on the measure of the circle. He rose to still more abstruse considerations in his treatise on the spiral. Archimedes is also the only one of the ancients who has left us anything satisfactory on the theory of mechanics and hydrostatics. He first taught the principle "that a body immersed in a fluid, loses as much in weight, as the weight of an equal volume of the fluid." He discovered this while bathing, which is said to have caused him so much joy that he ran home from the bath undressed, exclaiming, "I have found it; I have found it!" By means of this principle, he determined how much alloy a goldsmith had added to a crown which king Hiero had ordered of pure gold. Archimedes had a profound knowledge of mechanics, and in a moment of enthusiasm, with which the extraordinary performances of his machines had inspired him, he exclaimed that he "could move the earth with ease, by means of his machines placed on a fixed point near it." He was the inventor of the compound pulley, and probably of the endless screw which bears his name. He invented many surprising engines and machines. Some suppose that he visited Egypt, and raised the sites of the towns and villages of Egypt, and begun those mounds of earth by means of which communication was kept up from town to town, during the inundations of the Nile. When Marcellus, the Roman consul, besieged Syracuse, he devoted all his talents to the defense of his native country. He constructed machines which suddenly raised up in the air the ships of the enemy in the bay before the city, and then let them fall with such violence into the water that they sunk; he also set them on fire with his burning glasses. Polybius, Livy, and Plutarch speak in detail, with wonder and admiration, of the machines with which he repelled the attacks of the Romans. When the town was taken and given up to pillage, the Roman general gave strict orders to his soldiers not to hurt Archimedes, and even offered a reward to him who should bring him alive and safe to his presence. All these precautions proved useless, for the philosopher was so deeply engaged at the time in solving a problem, that he was even ignorant that the enemy were in possession of the city, and when a soldier entered his apartment, and commanded him to follow him, he exclaimed, according to some, "Disturb not my circle!" and to others, he begged the soldier not to "kill him till he had solved his problem"; but the rough warrior, ignorant of the august person before him, little heeded his request, and struck him down. This happened B.C. 212, so that Archimedes, at his death, must have been about 75 years old. Marcellus raised a monument over him, and placed upon it a cylinder and a sphere, thereby to immortalize his discovery of their mutual relations, on which he set a particular value; but it remained long neglected and unknown, till Cicero, during his questorship of Sicily, found it near one of the gates of Syracuse, and had it repaired. The story of his burning glasses had always appeared fabulous to some of the moderns, till the experiments of Buffon demonstrated its truth and practicability. These celebrated glasses are supposed to have been reflectors made of metal, and capable of producing their effect at the distance of a bow-shot.

THE TRIALS OF GENIUS.

FILIPPO BRUNELLESCHI.

This eminent architect was one of those illustrious men, who, having conceived and matured a grand design, proceed, cool, calm, and indefatigable, to put it in execution, undismayed by obstacles that seem insuperable, by poverty, want, and what is worse, the jeers of men whose capacities are too limited to comprehend their sublime conceptions. The world is apt to term such men enthusiasts, madmen, or fools, till their glorious achievements stamp them almost divinely inspired.

Brunelleschi was nobly descended on his mother's side, she being a member of the Spini family, which, according to Bottari, became extinct towards the middle of the last century. His ancestors on his father's side were also learned and distinguished men--his father was a notary, his grandfather "a very learned man," and his great-grandfather "a famous physician in those times." Filippo's father, though poor, educated him for the legal or medical profession; but such was his passion for art and mechanics, that his father, greatly against his will, was compelled to allow him to follow the bent of his genius: he accordingly placed him, at a proper age, in the Guild of the Goldsmiths, that he might acquire the art of design. Filippo soon became a proficient in the setting of precious stones, which he did much better than any old artists in the vocation. He also wrought in niello, and executed several figures which were highly commended, particularly two figures of Prophets, for an altar in the Cathedral of Pistoja. Filippo next turned his attention to sculpture, and executed works in basso-relievo, which showed an extraordinary genius. Subsequently, having made the acquaintance of several learned men, he began to turn his attention to the computation of the divisions of time, the adjustment of weights, the movement of wheels, etc. He next bent his thoughts to the study of perspective, to which, before his time, so little attention was paid by artists, that the figures often appeared to be slipping off the canvas, and the buildings had not a true point of view. He was one of the first who revived the Greek practice of rendering the precepts of geometry subservient to the painter; for this purpose, he studied with the famous geometrician Toscanelli, who was also the instructor, friend, and counsellor of Columbus. Filippo pursued his investigations until he brought perspective to great perfection; he was the first who discovered a perfectly correct method of taking the ground plan and sections of buildings, by means of intersecting lines--"a truly ingenious thing," says Vasari, "and of great utility to the arts of design." Filippo freely communicated his discoveries to his brother artists. He was imitated in mosaic by Benedetto da Macano, and in painting by Masaccio, who were his pupils. Vasari says Brunelleschi was a man of such exalted genius, that "we may truly declare him to have been given to us by Heaven, for the purpose of imparting a new spirit to architecture, which for hundreds of years had been lost; for the men of those times had badly expended great treasures in the erection of buildings without order, constructed in a most wretched manner, after deplorable designs, with fantastic inventions, labored graces, and worse decorations. But it then pleased Heaven, the earth having been for so many years destitute of any distinguished mind and divine genius, that Filippo Brunelleschi should leave to the world, the most noble, vast, and beautiful edifice that had ever been constructed in modern times, or even in those of the ancients; giving proof that the talent of the Tuscan artists, although lost for a time, was not extinguished. He was, moreover, adorned by the most excellent qualities, among which was that of kindliness, insomuch that there never was a man of more benign and amicable disposition; in judgment he was calm and dispassionate, and laid aside all thought of his own interest and even that of his friends, whenever he perceived the merits and talents of others to demand that he should do so. He knew himself, instructed many from the stores of his genius, and was ever ready to succor his neighbor in all his necessities; he declared himself the confirmed enemy of all vice, and the friend of those who labored in the cause of virtue. Never did he spend his moments vainly, but, although constantly occupied in his own works, in assisting those of others, or administering to their necessities, he had yet always time to bestow on his friends, for whom his aid was ever ready."

In the meantime, Brunelleschi had studied architecture, and made such progress that he had already conceived two grand projects--the one was the revival of the good manner of ancient architecture, which was then extinct, and the other was to discover a method for constructing the cupola of the church of Santa Maria del Fiore, in Florence, the difficulties of which were so great that, after the death of Arnolfo di Lapi, no architect had been found of sufficient courage and capacity to attempt the vaulting of that cupola.[1] If he could accomplish one or both of these designs, he believed that he would not only immortalize his own name, but confer a lasting benefit on mankind. Filippo, having resolved to devote himself entirely to architecture in future, set out for Rome in company with his friend Donatello, without imparting his purpose to any one. Here his mind became so absorbed that he labored incessantly, scarcely allowing himself the rest which nature required. He examined, measured, and made careful drawings of all the edifices, ruins, arches, and vaults of antiquity; to these he devoted perpetual study, and if by chance he found fragments of capitals, columns, cornices, or basements of buildings, partly buried in the earth, he set laborers at work to lay them open to view. One day, Filippo and Donatello found an earthen vase full of ancient coins, which caused a report to be spread about Rome that the artists were _treasure-seekers_, and this name they often heard, as they passed along the streets, negligently clothed, the people believing them to be men who studied geomancy, for the discovery of treasures. Donatello soon returned to Florence, but Filippo pursued his studies with unremitting diligence. Having exhausted his means, although he lived in the most frugal manner, he contrived to supply his wants, says Milizia, by pawning his jewels, but Vasari with greater probability, by setting precious stones for the goldsmiths, who were his friends. "Nor did he rest," says Vasari, "until he had drawn every description of fabric--temples, round, square, or octagon; basilicas, aqueducts, baths, arches, the Colosseum, amphitheatres, and every church built of bricks, of which he examined all the modes of binding and clamping, as well as the turning of the vaults and arches; he took note, likewise, of all the methods used for uniting the stones, as well as of the means used for securing the equilibrium and close conjunction of all the parts; and having found that in all the larger stones there was a hole, formed exactly in the centre of each on the under side, he discovered that this was for the insertion of the iron instrument with which the stones are drawn up, and which is called by us the mason's clamps (_la ulivella_), an invention, the use of which he restored, and ever afterwards put in practice. The different orders were next divided by his cares, each order, the Doric, Ionic, or Corinthian being placed apart; and such was the effect of his zeal in that study, that he became capable of entirely reconstructing the city in his imagination, and of beholding Rome as she had been before she was ruined. But in the year 1407 the air of the place caused Filippo some slight indisposition, when he was advised by his friends to try change of air. He consequently returned to Florence, where many buildings had suffered by his absence, and for these he made many drawings and gave numerous counsels on his return.

"In the same year an assemblage of architects and engineers was gathered in Florence, by the Superintendents of the works of Santa Maria del Fiore, and by the Syndics of the Guild of wool-workers, to consult on the means by which the cupola might be raised. Among these appeared Filippo, who gave it as his opinion that the edifice above the roof must be constructed, not after the design of Arnolfo, but that a frieze, fifteen braccia high, must be erected, with a large window in each of its sides: since not only would this take the weight off the piers of the tribune, but would also permit the cupola itself to be more easily raised."

The obstacles appeared so insuperable to the Superintendents and the Syndics, that they delayed the execution of the cupola for several years. In the meantime, Filippo secretly made models and designs for his cupola, which perpetually occupied his thoughts. He boldly asserted that the project was not only practicable, but that it could be done with much less difficulty and at less expense than was believed. At length, his boldness, genius, and powerful arguments, brought many of the citizens to his opinion, though he refused to show his models, because he knew the powerful opposition and influences he would have to encounter, and the almost certain loss of the honor of building the cupola, which he coveted above everything else. Vasari thus continues his admirable history: "But one morning the fancy took him, hearing that there was some talk of providing engineers for the construction of the cupola, of returning to Rome, thinking that he would have more reputation and be more sought for from abroad, than if he remained in Florence. When Filippo had returned to Rome accordingly, the acuteness of his genius and his readiness of resource were taken into consideration, when it was remembered that in his discourses he had showed a confidence and courage that had not been found in any of the other architects, who stood confounded, together with the builders, having lost all power of proceeding; for they were convinced that no method of constructing the cupola would ever be found, nor any beams that would make a scaffold strong enough to support the framework and weight of so vast an edifice. The Superintendents were therefore resolved to have an end of the matter, and wrote to Filippo in Rome, entreating him to repair to Florence, when he, who desired nothing better, returned very readily. The wardens of Santa Maria del Fiore and the syndics of the Guild of Woolworkers, having assembled on his arrival, set before him all the difficulties, from the greatest to the smallest, which had been made by the masters, who were present, together with himself, at the audience: whereupon Filippo replied in these words--'Gentlemen Superintendents, there is no doubt that great undertakings always present difficulties in their execution; and if none ever did so before, this of yours does it to an extent of which you are not perhaps even yet fully aware, for I do not know that even the ancients ever raised so enormous a vault as this will be. I, who have many times reflected on the scaffoldings required, both within and without, and on the method to be pursued for working securely at this erection, have never been able to come to a decision; and I am confounded, no less by the breadth than the height of the edifice. Now, if the cupola could be arched in a circular form, we might pursue the method adopted by the Romans in erecting the Pantheon of Rome; that is, the Rotunda. But here we must follow the eight sides of the building, dove-tailing, and, so to speak, enchaining the stones, which will be a very difficult thing. Yet, remembering that this is a temple consecrated to God and the Virgin, I confidently trust, that for a work executed to their honor, they will not fail to infuse knowledge where it is now wanting, and will bestow strength, wisdom, and genius on him who shall be the author of such a project. But how can I help you in the matter, seeing that the work is not mine? I tell you plainly, that if it belonged to me, my courage and power would beyond all doubt suffice to discover means whereby the work might be effected without so many difficulties; but as yet I have not reflected on the matter to any extent, and you would have me tell you by what method it is to be accomplished. But even if your worships should determine that the cupola shall be raised, you will be compelled not only to make trial of me, who do not consider myself capable of being the sole adviser in so important a matter, but also to expend money, and to command that within a year, and on a fixed day, many architects shall assemble in Florence; not Tuscans and Italians only, but Germans, French, and of every other nation: to them it is that such an undertaking should be proposed, to the end that having discussed the matter and decided among so many masters, the work may be commenced and entrusted to him who shall give the best evidence of capacity, or shall display the best method and judgment for the execution of so great a charge. I am not able to offer you other counsel, or to propose a better arrangement than this.'

"The proposal and plan of Filippo pleased the Syndics and Wardens of the works, but they would have liked that he should meanwhile prepare a model, on which they might have decided. But he showed himself to have no such intention, and taking leave of them, declared that he was solicited by letters to return to Rome. The syndics then perceiving that their request and those of the wardens did not suffice to detain him, caused several of his friends to entreat his stay; but Filippo not yielding to these prayers, the wardens, one morning, ordered him a present of money; this was on the 26th of May, 1417, and the sum is to be seen among the expenses of Filippo, in the books of the works. All this was done to render him favorable to their wishes; but, firm to his resolution, he departed nevertheless from Florence and returned to Rome, where he continued the unremitting study of the same subject, making various arrangements and preparing himself for the completion of that work, being convinced, as was the truth, that no other than himself could conduct such an undertaking to its conclusion. Nor had Filippo advised the syndics to call new architects for any other reason, than was furnished by his desire that those masters should be the witnesses of his own superior genius: he by no means expected that they could or would receive the commission for vaulting that tribune, or would undertake the charge, which he believed to be altogether too difficult for them. Much time was meanwhile consumed, before the architects, whom the syndics had caused to be summoned from afar, could arrive from their different countries. Orders had been given to the Florentine merchants resident in France, Germany, England, and Spain, who were authorized to spend large sums of money for the purpose of sending them, and were commanded to obtain from the sovereigns of each realm the most experienced and distinguished masters of the respective countries.
