An ambuscade of guards and eunuchs had been posted by the command of Theodora; they rushed with drawn swords to seize or to punish the guilty minister: he was saved by the fidelity of his attendants; but instead of appealing to a gracious sovereign, who had privately warned him of his danger, he pusillanimously fled to the sanctuary of the church.

The favorite of Justinian was sacrificed to conjugal tenderness or domestic tranquility; the conversion of a praefect into a priest extinguished his ambitious hopes: but the friendship of the emperor alleviated his disgrace, and he retained in the mild exile of Cyzicus an ample portion of his riches.

Such imperfect revenge could not satisfy the unrelenting hatred of Theodora; the murder of his old enemy, the bishop of Cyzicus, afforded a decent pretence; and John of Cappadocia, whose actions had deserved a thousand deaths, was at last condemned for a crime of which he was innocent.

A great minister, who had been invested with the honors of consul 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.
