Kīrilus

This name derives from the Greek “Kýrillos ‎(Κύριλλος),” which in turn derives from kúrios ‎(κύριος) kúrillos ‎(κύριλλος),” meaning “lord, master, guardian, ruler, owner, governing, having power.” 1) Constantine, better known by the monastic name of Cyril (826/827-869), was the evangelist of Pannonia and Moravia in the 9th century and the inventor of the Glagolitic alphabet. He is venerated as a saint by the Catholic Church and the Orthodox Church together with his brother Methodius (815/825–885), also a Byzantine evangelist of the Slav peoples. 2) Cyril of Alexandria (~376–444) was the Patriarch of Alexandria from 412 to 444. He was elevated when the city was at the height of its influence and power within the Roman Empire. The Cyrillic script is an alphabetic writing system employed across Eastern Europe, North, and Central Asian countries. It’s based on the Early Cyrillic, which was developed in the First Bulgarian Empire during the 9th-century AD at the Pre-Slavonic Literary School.
