Brother of Saint Methodius. Greek nobility; his family was connected with the senate of Thessalonica, and his mother Maria may have been Slavic. Studied at the University of Constantinople, and taught philosophy there. Deacon. Priest. Librarian at the church of Santa Sophia. Monk, taking the name Cyril. Sent with Methodius by the emperor in 861 to convert the Jewish Khazars of Russia, a mission that was successful, and which allowed him to learn the Khazar's language. In 863, sent with Methodius to convert Moravians in their native tongue. Though some western clergy opposed their efforts and refused to ordain their candidates for the priesthood, they did good work. Developed an alphabet for the Slavonic language that eventually became what is known as the Cyrillic today. After initial criticism for their use of it, they achieved approval of the Liturgy in the Slavonic language. May have been bishop, but may have died before the consecration ceremony.
