Old Church Slavonic or Church Slavonic is a literary language which
developed from the language used by St Cyril and St Methodius, 9th century
missionaries from Byzantium, to translate the bible and other religious works.
Cyril and Methodius based their translations on a Slavonic dialect of the
Thessalonika area and invented a new alphabet,
Glagolitic, in order to write them.
Sometime during the 10th century AD a new alphabet appeared which was
known as Cyrillic and named after St Cyril, though it was possibly invented
by St Kliment of Ohrid. The Cyrillic alphabet was used to write the Old Church
Slavonic language and was later adapated to write many other languages.
Old Church Slavonic was used as the liturgical language of the Russian Orthodox
church between the 9th and 12th centuries. A more modern form of the language,
known as Church Slavonic, appeared during the 14th century and is still used
in the Russian Orthodox church.
