Cyrillus (13), of Scythopolis (Bethshan), so called from his birthplace, a hagiologist, fl. c. 555. His father, John, was famous for his religious life. Cyril commenced an ascetic career at the age of 16. On leaving his monastery to visit Jerusalem and the holy places, his mother bid him put himself under the instruction of John the Silentiary, by whom he was commended to Leontius, abbat of the monastery of St. Euthymius, who admitted him as a monk in 522. Thence Cyril passed to the Laura of St. Saba, where he commenced his sacred biographies with the Lives of St. Euthymius and St. Saba, deriving his information from the elder monks who had known those saints. He also wrote the Life of St. John the Silentiary and other biographies, affording a valuable picture of the inner life of the Eastern church in the 6th cent. They have been unfortunately largely interpolated by Metaphrastes. The following biographies are attributed to Cyril by Fabricius ( Bibl. Graec. lib. v. c. 41, x. 155): (1) S. Joannes Silentiarius (ap. Surium, May 13); (2) S. Euthymius (Cotelerius, Eccl. Graec. Monum. ii. 200); (3) S. Sabas. ( ib. iii. 220); (4) Theodosius the Archimandrite (only found in Latin, of doubtful authenticity; (5) Cyriacus the Anchoret; (6) S. Theognius the Ascetic, bp. of Cyprus (Fabric. Bibl. Graec. u.s.; Cave, Hist. Lit. p. i. 529).
