onsul and patrician, was ignominiously scourged like the vilest of malefactors; a tattered cloak was the sole remnant of his fortunes; he was transported in a bark to the place of his banishment at Antinopolis in Upper Egypt, and the praefect of the East begged his bread through the cities which had trembled at his name. During an exile of seven years, his life was protracted and threatened by the ingenious cruelty of Theodora; and when her death permitted the emperor to recall a servant whom he had abandoned with regret, the ambition of John of Cappadocia was reduced to the humble duties of the sacerdotal profession. His successors convinced the subjects of Justinian, that the arts of oppression might still be improved by experience and industry; the frauds of a Syrian banker were introduced into the administration of the finances; and the example of the praefect was diligently copied by the quaestor, the public and private treasurer, the governors of provinces, and the principal magistrates of the Eastern empire. V. 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 experiment
