"Bartolomeo Ammanati, a Florentine architect and sculptor, sent expressly by the grand duke, presented himself before the pope, without either models or designs, and requested a year to consider it; for this he was most severely reprimanded by the pontiff. Fontana exhibited his wooden model, with a leaden pyramid, which, by means of a windlass and crane, was raised and lowered with the greatest facility; he explained the nature of these machines and movements, and gave a practical proof of their capability by raising a small pyramid in the mausoleum of Augustus, which was in a ruinous condition. After many disputes, Fontana's invention was approved; but, as he had not yet acquired a name of sufficient importance, the execution of it was committed to two architects of renown, Giacomo della Porta and Bartolomeo Ammanati.--These immediately commenced a scaffold in the centre of the square where the obelisk was to stand.

"Fontana being justly displeased that his own discovery should not be entrusted to his execution, went to the pope, and respectfully represented to him, that no one could so properly execute a design as the inventor. Sixtus was persuaded, and committed the entire direction of it to him. The architect then commenced his work with the utmost celerity. He dug a square hole of 44 feet, in the piazza, 24 feet deep, and finding the soil watery and chalky, he made it firm by strong and massive piles. At the same time he had ropes made, three inches in diameter, 1500 feet long, an immense quantity of cords, large iron rods to strengthen the obelisk, and other pieces of iron for the cases of the cranes, pins, circles, pivots, and instruments of every kind. The iron to secure the obelisk alone amounted to 40,000 lbs., and was made in the manufactories of Rome, Ronciglione, and Subbiaco. The beams, taken from the woods of Nettuno, were of such a prodigious size, that each was drawn by seven pair of buffalos. From Terracina, elm was brought, for the caseing, and Holm oak for the shafts of windlass; and to prevent the ground from giving way, it being soft and marshy, in consequence of the great weight, he made a bed with two layers of timber, crossing each other in a contrary direction. On this foundation he placed the castle or carriage, which had eight columns: each of these columns was composed of so many thick planks, that they measured 13 feet in circumference. These were united together by thick cords, without screws, in order to be done and undone with greater quickness. The height of the beams was required to be 90 feet; and not any being of that length, they were placed one on the other, and united by iron bands. These columns were strengthened by forty-eight braces, and tied together on all sides. The obelisk was entirely covered with double mats, to prevent its being injured; it was then surrounded by planks, over which were placed large rods of iron, and these embracing the thick part underneath, came directly over the four faces of the mass, which thus became totally encircled with these coverings. The whole pyramid thus weighed one million and a half pounds. Fontana calculated that every windlass, with good ropes and cranes, would be able to move 20,000 lbs. weight; and consequently forty would move 800,000, and he gained the rest by five levers of thick beams 52 feet long.

"The architect gave an order that, at the sound of the trumpet, each should begin working, and at that of the bell, placed in the castle of wood, each should desist; there were more than 900 workmen, and 75 horses. The trumpet sounded, and in an instant, men, horses, windlasses, cranes, and levers were all in motion. The ground trembled, the castle cracked, all the planks bent from the enormous weight, and the pyramid, which inclined a foot towards the choir of St. Peter, was raised perpendicularly. The commencement having prospered so well, the bell sounded a rest. In twelve more movements the pyramid was raised almost two feet from the ground, in such a situation that it could be placed on the rollers, and it remained firmly fixed by means of wedges of iron and wood. At this happy event the castle of St. Angelo discharged all its artillery, and a universal joy pervaded the whole city.

"Fontana was now convinced that the ropes were better than iron bands, these being most broken or distorted, or expanded by the weight. On the 7th of May the pyramid was placed on the sledge--a more difficult and tedious operation than that of raising it, it being necessary to convey it over the piazza to the situation intended for it, which was 115 rods from where it then stood. The level of the piazza being about 30 feet lower, it was necessary to throw up an earthen embankment from one place to the other, well secured by piles, &c. This being done, on the 13th of June, by means of four windlasses, the pyramid was removed with the greatest facility on the rollers, to the place of its destination. The pope deferred its erection to the next autumn, lest the summer heats should injure the workmen and spectators.

"For this undertaking, Fontana was created a knight of the Golden Spur, and a Roman nobleman; he had a pension of 2000 crowns, transferable to his heirs, ten knighthoods, 5000 crowns of gold in ready money, and every description of material used in the work, which was valued at more than 20,000 crowns. Two bronze medals of him were struck; and the following inscription was placed on the base of the pyramid by order of the pope:--"

REMOVAL OF AN OBELISK FROM THEBES TO PARIS.

In 1833, the French removed the smallest of the two obelisks which stood before the propylon of the temple of Luxor to Paris, and elevated it in the Place de la Concorde. The shaft is 76 feet high, and eight feet wide on the broadest side of the base; the pedestal is 10 feet square by 16 feet high. Permission for the removal of both the obelisks having been granted to the French government by the Viceroy of Egypt, a vessel constructed for the purpose was sent out in March, 1831, under M. Lebas, an eminent engineer, to whom the undertaking was confided, it being previously determined to bring away only one, and M. Lebas found it sufficiently difficult to bring away the smallest of the two. After three months' labor with 800 men, the obelisk was removed on an inclined plane into the vessel, through a hole made in the end for the purpose. It arrived safely up the Seine to Paris, Dec. 23d, 1833. An inclined plane of solid masonry was then constructed, leading from the river up to a platform, also of rough masonry, level with the top of the pedestal. The obelisk, having been placed on a kind of timber car or sledge, was drawn up by means of ropes and capstans. One edge of the base having been brought to its place on the pedestal, it was raised to a perpendicular position by ropes and pulleys attached to the heads of ten masts, five on each side. When all was ready, the obelisk was elevated to its place under the direction of M. Lebas, in three hours, without the least accident, Oct. 25th, 1836. It is said that Lebas had provided himself with loaded pistols, in the firm determination to blow out his brains in case of an accident!

In 1820, the Viceroy of Egypt presented to the English government the monolith lying on the ground at Alexandria, one of the two obelisks called Cleopatra's Needles; the other is still standing. The project of removing it to London and erecting it in Waterloo Square, was entertained for some time by the English government, but seems to have been long abandoned; recently, however, an expedition is being fitted out for the purpose.

CARBURI'S BASE FOR THE EQUESTRIAN STATUE OF PETER THE GREAT.

COMPARATIVE SKILL OF THE ANCIENTS AND MODERNS IN MECHANICS.

Many persons suppose, and maintain, that the grandeur of the monuments of the ancients, and the great size of the stones they employed for building purposes, prove that they understood mechanics better than the moderns. The least knowledge in mechanics, however, will show this opinion to be erroneous. The moderns possess powers which were unknown to the ancients, as the screw, and the hydraulic press, the power of which last is only limited by the strength of the machinery. The works of the ancients show that they expended a vast deal of power and labor to gratify the pride and ambition of kings; but the moderns can do all these things much easier, and in far less time, whenever they deem it proper. There was nothing in ancient times to be compared with that daring, ingenious, and stupendous monument of engineering skill--the Britannia Tubular Bridge, across the Menai straits--projected, designed, and built by Robert Stephenson, the famous English engineer. He had previously built a similar but smaller structure--the Conway Tubular Bridge.

THE BRITANNIA TUBULAR RAILWAY BRIDGE.

The Britannia Tubular Bridge was built to conduct the Chester and Holyhead Railway across the Menai Straits, to the island of Anglesea, in the Irish Sea.

The difficulties which the engineer had to overcome, were greatly augmented by the peculiar form and situation of the straits. Sir Francis Head says, "The point of the straits which it was desired to cross, although broader than that about a mile distant; preoccupied by Mr. Telford's suspension bridge--was of course one of the narrowest that could be selected, in consequence of which the ebbing and flowing torrent rushes through it with such violence, that, except where there is back water, it is often impossible for a small boat to pull against it; besides which, the gusts of wind which come over the tops, down the ravines, and round the sides of the neighboring mountains, are so sudden, and occasionally so violent, that it is as dangerous to sail as it is difficult to row; in short, the wind and the water, sometimes playfully and sometimes angrily, seem to vie with each other--like some of Shakspeare's fairies--in exhibiting before the stranger the utmost variety of fantastic changes which it is in the power of each to assume." The Menai Straits are about twelve miles long, through which, imprisoned between the precipitous shores, the waters of the Irish Sea and St. George's Channel are not only everlastingly vibrating, backwards and forwards, but at the same time and from the same causes, are progressively rising and falling 20 to 25 feet, with each successive tide, which, varying its period of high water, every day forms altogether an endless succession of aqueous changes.

THE TUBES.

The tubes forming the viaducts, rest upon two abutments and three piers, called respectively the Anglesea abutment and pier, the Carnarvon abutment and pier, and the Britannia or central pier, built upon the Britannia rock in the middle of the straits, which gives name to the bridge. The Anglesea abutment is 143 feet 6 inches high, 55 feet wide, and 175 feet long to the end of the wings, which terminate in pedestals, supporting colossal lions on either side, 25 feet 6 inches in length, 12 feet 6 inches high, and 8 feet broad, carved out of a single block of Anglesea marble. The space between the Anglesea abutment and pier is 230 feet. This pier is 196 feet high, 55 feet wide, and 32 feet long. The Carnarvon abutment and pier are of the same dimensions as those above described, on the opposite shore. The Britannia pier is 240 feet high, 55 feet wide, and 45 feet long. This pier is 460 feet clear of each of the two side piers. The bottom of the tubes are 124 feet above low water mark, so that large ships can pass under them, under full sail.

CONSTRUCTION OF THE TUBES.

The sides, bottom, and top of these gigantic tubes are formed of oblong wrought iron plates, varying in length, width, and thickness, according to circumstances, but of amazing size and weight. They are so arranged as to obtain the greatest possible strength, the whole being riveted together in the strongest manner. In addition to the 1600 tons of wrought iron in each of the four large pieces, an additional 200 tons was used to form lifting frames, and cast iron beams for the purpose of attaching the tube to those huge chains by which they were elevated. The construction of the tubes is thus described in the London Illustrated News, from which this account is derived:

"In order to carry out this vast work , eighty houses have been erected for the accommodation of the workmen, which, being whitewashed, have a peculiarly neat and picturesque appearance; among them are seen butcher's, grocer's, and tobacconist's shops, supplying the wants of a numerous population. A day school, Sunday school, and meeting-house also conspicuously figure. Workshops, steam-engines, store-houses, offices, and other buildings meet the eye at every turn; one is led to conclude that a considerable time has elapsed since the works were commenced, yet it is little more than two years ago. A stranger, on coming to the ground, is struck with wonder when for the first time he obtains a near view of the vast piles of masonry towering majestically above all the surrounding objects--strong as the pillars of Hercules, and apparently as endurable--his eyes wander instinctively to the ponderous tubes, those masterpieces of engineering constructiveness and mathematical adjustment; he shrinks into himself as he gazes, and is astonished when he thinks that the whole is the developed idea of one man, and carried out, too, in the face of difficulties which few would have dared to encounter."

FLOATING OF THE TUBES.

The tubes were floated to the places whence they were elevated to their positions on eight huge pontoons, fitted with valves and pumps to exhaust the water from them, when all was ready to float the prodigious iron beams. These pontoons or boxes were each 90 feet long, 25 feet wide, and 15 feet deep. The pontoons having been placed under one of the tubes , the floating was easily effected, and the operation is thus described by the "Assistant Engineer."

"The operation of floating the tubes , will be commenced by closing the valves in the pontoons at low water; as the tide rises, the pontoons will begin to float, and shortly afterwards to bear the weight of the tube, which will at last be raised by them entirely off its temporary supporting piers; about an hour and a half before high water, the current running about four miles an hour, it will be dragged out into the middle of the stream, by powerful capstans and hawsers, reaching from the pontoons at each end, to the opposite shore. In order to guide it into its place with the greatest possible certainty, three large hawsers will be laid down the stream, one end of two of them being made fast to the towers between which the tube is intended to rest, and the other to strong fixed points on the two shores, near to and opposite the further end of the tube platforms; in their course, they will pass over and rest upon the pontoons, being taken through 'cable-stoppers' which are contrivances for embracing and gripping the hawser extended across the stream, and thereby retarding, or if necessary entirely destroying, the speed induced by the current."

RAISING THE TUBES

The tubes of the Britannia bridge were raised by means of three hydraulic presses of the most prodigious size, strength, weight, and power; two of which were placed in the Britannia pier, above the points where the tubes rest, and the other alternately on the Anglesea and Carnarvon piers.

The tubes on the Anglesea side were raised first. The presses in the Britannia tower were each capable of raising a weight of 1250 tons; that in the Anglesea tower, larger than the others, 1800 tons, or the whole weight of the tube. These presses were worked by two steam engines of 40 horse power each, which forced the water into the cylinders, through a tube half an inch in diameter. These steam engines were placed in the Britannia and Anglesea piers. The press in the Anglesea pier is thus described, the others being constructed in the same manner. The hydraulic press stands on massive beams of wrought iron plates constructed on the principle of the arch, placed in the tower above the points where the tubes rest. The press consists of a huge cylinder, 9 feet 2 inches in length, 3 feet 6 inches outside diameter, and the ram 1 foot 8 inches in diameter, making the sides and bottom of the cylinder 11 inches thick; it was calculated that it would resist a pressure of 8000 or 9000 pounds to the square inch. The ram or piston was attached to an exceedingly thick and heavy beam of cast iron, called the cross-head, strengthened with bars of wrought iron. To the cross-head were attached the huge chains that descended to the tubes far below, to which they were secured, so that, as the ram was forced up 6 feet at each stroke, the tube was raised the same distance. "The power of the press is exerted on the tube by aid of chains, the links of which are 6 feet in length, bolted together in sets of eight or nine links alternately.--The ram raises the cross-head 6 feet at each stroke, and with it the tube, when that height is attained, a lower set of chains on the beams grip the next set of links, and thus prevent them from slipping down, whilst the clamps on the cross-heads are unscrewed, the upper links taken off, and the ram and cross-head lowered to take another stroke." To guard against all chances of injury to the tubes in case of accident to the machinery, a contrivance was adopted by which the tubes were followed up with wedges. The importance of this precaution was fully proved on the very first attempt to raise the tube on the Anglesea side, when the huge cylinder broke, almost at the commencement of the operations. The following is the engineer's interesting report of the accident:

"On Friday last , at a quarter to twelve o'clock, we commenced lifting the tube at the Anglesea end, intending to raise it six feet, and afterwards to have raised the opposite end the same height.

"The tube rose steadily to the height of two feet six inches, being closely followed up by inch wooden boards packed beneath it, when suddenly, and without any warning, the bottom of the hydraulic press gave way, separating completely from the body of the press.

"The ram, cross-head, and chains descended violently on the press, with a tremendous noise, the tube sinking down upon the wooden packing beneath it. The bottom of the press, weighing nearly two tons and a half, fell on the top of the tube, a depth of eighty feet.

"A sailor, named Owen Parry, was ascending a rope ladder at the time, from the top of the tube into the tower; the broken piece of press in its descent struck the ladder and shook him off; he fell on to the tube, a height of fifty feet, receiving a contusion of the skull, and other injuries, of so serious a nature that he died the same evening. He was not engaged in the raising, and had only chosen to cross the tube, as being the nearest road from one tower to the other. An inquest was held on the following day, and a verdict of accidental death returned. No one actually engaged in the operation was injured, although Mr. Edwin Clark, who was superintending the operation, on the top of the cross-head, and his brother, Mr. L. Clark, who was standing beneath it, had both a very narrow escape.

"The tube is not at all injured, but some portions of the cast iron lifting frames are broken, and require repairing; some weeks must elapse before a new cylinder is made, and the operation continued."

Notwithstanding these "incomprehensible" speculations, the tubes are abundantly strong to sustain the pressure of the heaviest trains, even were they to stand still in the middle of the bridge. It is calculated that each tube, in its weakest part, would sustain a pressure of four or five thousand tons, "support a line of battle ship, with all her munitions and stores on board," and "bear a line of locomotives covering the entire bridge." The bridge was completed, and the first train passed through it March 5th, 1850. The total cost of this gigantic structure was only ?601,865.

GLORY OF ANCIENT ROME.

Ancient Rome was built upon seven hills, which are now scarcely discoverable on account of the vast quantities of rubbish with which the valleys are filled. Pliny estimates the circumference of the city in his time at 13,000 paces , and the population at 3,000,000. Rome was filled with magnificent public edifices, temples, theatres, amphitheatres, circuses, naumachiae, porticos, basilicae, baths, gardens, triumphal arches, columns, sewers, aqueducts, sepulchres, public and private palaces, etc.

In the time of the Caesars, fourteen magnificent aqueducts, supported by immense arches, conducted whole rivers into Rome, from a distance of many miles, and supplied one hundred and fifty public fountains, one hundred and eighteen large public baths, the artificial seas in which naval combats were represented in the Colosseum, and the golden palace of Nero, besides the water necessary to supply the daily use of the inhabitants. One hundred thousand marble and bronze statues ornamented the public squares, the temples, the streets, and the houses of the nobility: ninety colossal statues raised on pedestals; and forty-eight Egyptian obelisks of red granite, some of the largest size, also adorned the city.

Such was ancient Rome, "the Eternal City." Although visited for more than a thousand years by various calamities, she is still the most majestic of cities; the charm of beauty, dignity, and grandeur still lingers around the ruins of ancient, as well as the splendid structures of modern Rome, and brilliant recollections of every age are connected with the monuments which the passing traveler meets at every step.

THE CAPITOL.

MODERN ROME.

THE FOUNDATION OF VENICE.

It is recorded in the archives of Padua, says Milizia, that when Rhadagasius entered Italy, and the cruelties exercised by the Visigoths obliged the people to seek refuge in various places, an architect of Candia, named Eutinopus, was the first to retire to the fens of the Adriatic, where he built a house, which remained the only one there for several years. At length, when Alaric continued to desolate the country, others sought an asylum in the same marshes, and built twenty-four houses, which formed the germ of Venice. The security of the place now induced people to settle there rapidly, and Venice soon sprung up a city and gradually rose to be mistress of the seas. The Venetian historians inform us that the house of Eutinopus, during a dreadful conflagration, was miraculously saved by a shower of rain, at the prayer of the architect, who made a vow to convert it into a church; he did this, and dedicated it to St. James, the magistrates and inhabitants contributing to build and ornament the edifice. The church is still standing, in the quarter of the Rialto, which is universally considered the oldest part of Venice.

THEODORIC THE GREAT, AND HIS LOVE OF THE FINE ARTS.

Theodoric, king of the Ostrogoths, and afterwards also king of Italy, was born at Amali, near Vienna, in 455, and died in 526. Though a Goth, he was so far from delighting in the destruction of public monuments, and works of art, that he issued edicts for their preservation at Rome and throughout Italy, and assigned revenues for the repair of the public edifices, for which purpose he employed the most skillful and learned architects, particularly Alo?sius, Bo?tius, and Symmachus. According to Cassiodorus , Theodoric said: "It is glorious to preserve the works of antiquity; and it is our duty to restore the most useful and the most beautiful." Symmachus had the direction of the buildings constructed or rebuilt at Rome. The king thus wrote to him: "You have constructed fine edifices; you have, moreover, disposed of them with so much wisdom that they equal those of antiquity, and serve as examples to the moderns; and all you show us is a perfect image of the excellence of your mind, because it is not possible to build correctly without good sense and a well cultivated understanding."

In his directions to the Prefect of Rome, on the architecture of the public edifices, Theodoric thus wrote:

"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."

ARCHIMEDES.

THE TRIALS OF GENIUS.

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 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.'
