Monk, scholar, theologian, and linguist (born Salonika
?,
Greece,
827; died
Rome,
February 4,
869). With his brother
Methodius he is credited with inventing the
Glagolitic alphabet a precursor to the
Cyrillic alphabet. The two convinced the Pope that the
Slavs needed a
Bible in their own language. He and his brother taught the alphabet as missionaries in
Moravia.
Sorry I can not parse this:
His work was later transmitted by his pupils who made the journey back from Moravia to Bulgaria. Cyril, however, did not invent the alphabet on Bulgarian territory.
Cyril was canonized as a saint by the Orthodox Church and is also called "apostle of the Slavs".
