The edifices of Justinian were cemented with the blood and treasure of his people; but those stately structures appeared to announce the prosperity of the empire, and actually displayed the skill of their architects. Both the theory and practice of the arts which depend on mathematical science and mechanical power, were cultivated under the patronage of the emperors; the fame of Archimedes was rivalled by Proclus and Anthemius; and if their miracles had been related by intelligent spectators, they might now enlarge the speculations, instead of exciting the distrust, of philosophers. A tradition has prevailed, that the Roman fleet was reduced to ashes in the port of Syracuse, by the burning-glasses of Archimedes; and it is asserted, that a similar expedient was employed by Proclus to destroy the Gothic vessels in the harbor of Constantinople, and to protect his benefactor Anastasius against the bold enterprise of Vitalian. A machine was fixed on the walls of the city, consisting of a hexagon mirror of polished brass, with many smaller and movable polygons to receive and reflect the rays of the meridian sun; and a consuming flame was darted, to the distance, perhaps of two hundred feet. The truth of these two extraordinary facts is invalidated by the silence of the most authentic historians; and the use of burning-glasses was never adopted in the attack or defence of places. Yet the admirable experiments of a French philosopher have demonstrated the possibility of such a mirror; and, since it is possible, I am more disposed to attribute the art to the greatest mathematicians of antiquity, than to give the merit of the fiction to the idle fancy of a monk or a sophist. According to another story, Proclus applied sulphur to the destruction of the Gothic fleet; in a modern imagination, the name of sulphur is instantly connected with the suspicion of gunpowder, and that suspicion is propagated by the secret arts of his disciple Anthemius. A citizen of Tralles in Asia had five sons, who were all distinguished in their respective professions by merit and success. Olympius excelled in the knowledge and practice of the Roman jurisprudence. Dioscorus and Alexander became learned physicians; but the skill of the former was exercised for the benefit of his fellow-citizens, while his more ambitious brother acquired wealth and reputation at Rome. The fame of Metrodorus the grammarian, and of Anthemius the mathematician and architect, reached the ears of the emperor Justinian, who invited them to Constantinople; and while the one instructed the rising generation in the schools of eloquence, the other filled the capital and provinces with more lasting monuments of his art. In a trifling dispute relative to the walls or windows of their contiguous houses, he had been vanquished by the eloquence of his neighbor Zeno; but the orator was defeated in his turn by the master of mechanics, whose malicious, though harmless, stratagems are darkly represented by the ignorance of Agathias. In a lower room, Anthemius arranged several vessels or caldrons of water, each of them covered by the wide bottom of a leathern tube, which rose to a narrow top, and was artificially conveyed among the joists and rafters of the adjacent building. A fire was kindled beneath the caldron; the steam of the boiling water ascended through the tubes; the house was shaken by the efforts of imprisoned air, and its trembling inhabitants might wonder that the city was unconscious of the earthquake which they had felt. At another time, the friends of Zeno, as they sat at table, were dazzled by the intolerable light which flashed in their eyes from the reflecting mirrors of Anthemius; they were astonished by the noise which he produced from the collision of certain minute and sonorous particles; and the orator declared in tragic style to the senate, that a mere mortal must yield to the power of an antagonist, who shook the earth with the trident of Neptune, and imitated the thunder and lightning of Jove himself. The genius of Anthemius, and his colleague Isidore the Milesian, was excited and employed by a prince, whose taste for architecture had degenerated into a mischievous and costly passion. His favorite architects submitted their designs and difficulties to Justinian, and discreetly confessed how much their laborious meditations were surpassed by the intuitive knowledge of celestial inspiration of an emperor, whose views were always directed to the benefit of his people, the glory of his reign, and the salvation of his soul.","notes":[{"id":"95","text":"This conflagration is hinted by Lucian (in Hippia, c. 2) and Galen, (l. iii. de Temperamentis, tom. i. p. 81, edit.

No sooner did the tumult subside, than the Christian populace deplored their sacrilegious rashness; but they might have rejoiced in the calamity, had they foreseen the glory of the new temple, which at the end of forty days was strenuously undertaken by the piety of Justinian. The ruins were cleared away, a more spacious plan was described, and as it required the consent of some proprietors of ground, they obtained the most exorbitant terms from the eager desires and timorous conscience of the monarch. Anthemius formed the design, and his genius directed the hands of ten thousand workmen, whose payment in pieces of fine silver was never delayed beyond the evening. The emperor himself, clad in a linen tunic, surveyed each day their rapid progress, and encouraged their diligence by his familiarity, his zeal, and his rewards. The new Cathedral of St. Sophia was consecrated by the patriarch, five years, eleven months, and ten days from the first foundation; and in the midst of the solemn festival Justinian exclaimed with devout vanity, “Glory be to God, who hath thought me worthy to accomplish so great a work; I have vanquished thee, O Solomon!” But the pride of the Roman Solomon, before twenty years had elapsed, was humbled by an earthquake, which overthrew the eastern part of the dome. Its splendor was again restored by the perseverance of the same prince; and in the thirty-sixth year of his reign, Justinian celebrated the second dedication of a temple which remains, after twelve centuries, a stately monument of his fame. The architecture of St. Sophia, which is now converted into the principal mosque, has been imitated by the Turkish sultans, and that venerable pile continues to excite the fond admiration of the Greeks, and the more rational curiosity of European travellers. The eye of the spectator is disappointed by an irregular prospect of half-domes and shelving roofs: the western front, the principal approach, is destitute of simplicity and magnificence; and the scale of dimensions has been much surpassed by several of the Latin cathedrals. But the architect who first erected an _aerial_ cupola, is entitled to the praise of bold design and skilful execution. The dome of St. Sophia, illuminated by four-and-twenty windows, is formed with so small a curve, that the depth is equal only to one sixth of its diameter; the measure of that diameter is one hundred and fifteen feet, and the lofty centre, where a crescent has supplanted the cross, rises to the perpendicular height of one hundred and eighty feet above the pavement. The circle which encompasses the dome, lightly reposes on four strong arches, and their weight is firmly supported by four massy piles, whose strength is assisted, on the northern and southern sides, by four columns of Egyptian granite.","notes":[{"id":"103","text":"Among the crowd of ancients and moderns who have celebrated the edifice of St. Sophia, I shall distinguish and follow, 1. Four original spectators and historians: Procopius, (de Edific. l. i. c. 1,) Agathias, (l. v. p. 152, 153,) Paul Silentiarius, (in a poem of 1026 hexameters, and calcem Annae Commen. Alexiad.,) and Evagrius, (l. iv. c. 31.) 2. Two legendary Greeks of a later period: George Codinus, (de Origin. C. P. p. 64-74,) and the anonymous writer of Banduri, (Imp.

That portico was the humble station of the penitents. The nave or body of the church was filled by the congregation of the faithful; but the two sexes were prudently distinguished, and the upper and lower galleries were allotted for the more private devotion of the women. Beyond the northern and southern piles, a balustrade, terminated on either side by the thrones of the emperor and the patriarch, divided the nave from the choir; and the space, as far as the steps of the altar, was occupied by the clergy and singers. The altar itself, a name which insensibly became familiar to Christian ears, was placed in the eastern recess, artificially built in the form of a demi-cylinder; and this sanctuary communicated by several doors with the sacristy, the vestry, the baptistery, and the contiguous buildings, subservient either to the pomp of worship, or the private use of the ecclesiastical ministers. The memory of past calamities inspired Justinian with a wise resolution, that no wood, except for the doors, should be admitted into the new edifice; and the choice of the materials was applied to the strength, the lightness, or the splendor of the respective parts. The solid piles which contained the cupola were composed of huge blocks of freestone, hewn into squares and triangles, fortified by circles of iron, and firmly cemented by the infusion of lead and quicklime: but the weight of the cupola was diminished by the levity of its substance, which consists either of pumice-stone that floats in the water, or of bricks from the Isle of Rhodes, five times less ponderous than the ordinary sort. The whole frame of the edifice was constructed of brick; but those base materials were concealed by a crust of marble; and the inside of St. Sophia, the cupola, the two larger, and the six smaller, semi-domes, the walls, the hundred columns, and the pavement, delight even the eyes of Barbarians, with a rich and variegated picture. A poet, who beheld the primitive lustre of St. Sophia, enumerates the colors, the shades, and the spots of ten or twelve marbles, jaspers, and porphyries, which nature had profusely diversified, and which were blended and contrasted as it were by a skilful painter. The triumph of Christ was adorned with the last spoils of Paganism, but the greater part of these costly stones was extracted from the quarries of Asia Minor, the isles and continent of Greece, Egypt, Africa, and Gaul. Eight columns of porphyry, which Aurelian had placed in the temple of the sun, were offered by the piety of a Roman matron; eight others of green marble were presented by the ambitious zeal of the magistrates of Ephesus: both are admirable by their size and beauty, but every order of architecture disclaims their fantastic capital. A variety of ornaments and figures was curiously expressed in mosaic; and the images of Christ, of the Virgin, of saints, and of angels, which have been defaced by Turkish fanaticism, were dangerously exposed to the superstition of the Greeks. According to the sanctity of each object, the precious metals were distributed in thin leaves or in solid masses. The balustrade of the choir, the capitals of the pillars, the ornaments of the doors and galleries, were of gilt bronze; the spectator was dazzled by the glittering aspect of the cupola; the sanctuary contained forty thousand pounds weight of silver; and the holy vases and vestments of the altar were of the purest gold, enriched with inestimable gems. Before the structure of the church had arisen two cubits above the ground, forty-five thousand two hundred pounds were already consumed; and the whole expense amounted to three hundred and twenty thousand: each reader, according to the measure of his belief, may estimate their value either in gold or silver; but the sum of one million sterling is the result of the lowest computation. A magnificent temple is a laudable monument of national taste and religion; and the enthusiast who entered the dome of St. Sophia might be tempted to suppose that it was the residence, or even the workmanship, of the Deity. Yet how dull is the artifice, how insignificant is the labor, if it be compared with the formation of the vilest insect that crawls upon the surface of the temple!","notes":[{"id":"105","text":"Paul Silentiarius, in dark and poetic language, describes the various stones and marbles that were employed in the edifice of St. Sophia, (P. ii. p. 129, 133, &c., &c.:) 1.
