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
