The Glagolitic alphabet was invented during the 9th century by the missionaries St Cyril (827-869 AD) and St Methodius (826-885 AD) in order to translate the Bible and other religious works into the language of the Great Moravia region. They probably modelled Glagolitic on a cursive form of the Greek alphabet, and based their translations on a Slavic dialect of the Thessalonika area, which formed the basis of the literary standard known as Old Church Slavonic.
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.
This chart shows the Glagolitic alphabet with the names of the letters in Old Church Slavonic, the Cyrillic equivalents of the letters, and IPA transcription.
