Old Church Slavonic
Authors

The history of Old Church Slavonic writing includes a northern tradition begun by the mission to Great Moravia, including a short mission in the Lower Pannonia, and a Bulgarian tradition begun by some of the missionaries who relocated to Bulgaria after the expulsion from Great Moravia.

The first texts written in Old Church Slavonic are translations of the Gospels and Byzantine liturgical texts begun by the Byzantine missionaries Saints Cyril and Methodius, mostly during their mission to Great Moravia.

The most important authors in Old Church Slavonic after the death of Methodius and the dissolution of the Great Moravian academy were Clement of Ohrid (active also in Great Moravia), Constantine of Preslav, Chernorizetz Hrabar and John Exarch, all of whom worked in medieval Bulgaria at the end of the 9th and the beginning of the 10th century. The full text of the Second Book of Enoch is only preserved in Old Church Slavonic, although the original most certainly had been in Greek or even Hebrew or Aramaic.
