Cyrus was one of the most conspicuous figures in the history of the city during the reign of Theodosius II.[177] On account of his talents and integrity he held the office of Prætorian Prefect, and that of Prefect of the City, for four years, making himself immensely popular by the character of his administration. During his prefecture, in 439, the new walls along the shores of the city were constructed. The fires and earthquakes, moreover, which devastated Constantinople in the earlier half of the fifth century, afforded him ample opportunity for carrying out civic improvements, and he was to be seen constantly driving about the city in his chariot to inspect the public buildings in course of erection, and to push forward their completion. Among other works, he restored the great Bath of Achilles, which had been destroyed in the fire of 433.[178] To him also is ascribed the introduction of the practice of lighting the shops and streets of the capital at night.[179] He was, moreover, a man of literary tastes, and a poet, who counted the Empress Eudoxia, herself a poetess, one of his admirers.[180] In the competition between Greek and Latin for ascendency as the official language of the Government, he took the side of the former by issuing his decrees in Greek, a practice which made the conservative Lydus style him ironically, “Our Demosthenes.”[181] But in the midst of all his success, Cyrus remained self-possessed and sober-minded. “I do not like Fortune, when she smiles much,”[182] he was accustomed to say; and at length the tide of his prosperity turned. Taking his seat one day in the Hippodrome, he was greeted with a storm of applause. “Constantine,” the vast assembly shouted, “founded the city; Cyrus restored it.” For a subject to be so popular was a crime. Theodosius took umbrage at the ovation accorded to the renovator of the city, and Cyrus was dismissed from office, deprived of his property, forced to enter the Church, and sent to Smyrna to succeed four bishops who had perished at the hands of brigands. Upon his arrival in that city on Christmas Day he found his people ill-prepared to receive him, so indignant were they that a man still counted a heathen and a heretic should have been appointed the shepherd of their souls. But a short allocution, which Cyrus delivered in honour of the festival, disarmed the opposition to him, and he spent the last years of his life in the diocese, undisturbed by political turmoils and unmolested by robbers.
