A Dictionary of Greek and Roman biography and mythology

5. Cyrus, St., was a native of Alexandria, where he practised medicine gratuitously and with great reputation. He was a Christian, and took every opportunity of endeavouring to convert his patients from paganism. During the persecution of Diocletian he fled to Arabia, where he was said to heal diseases not so much by his medicines as by miraculous powers. He was put to death with many tortures by the command of the prefect Syrianus, in company with several other martyrs, A. D. 300; and his remains were carried to Rome, and there buried. His memory is celebrated on the thirty-first of January both by the Romish and Greek churches. (Acta Sanctor.; Menolog. Graecor.; Bzovius, Nomencl. Sanctor. Professione Medicor.; C. B.
