John the Exarch was a prominent scholar, translator, and writer active in the First Bulgarian Empire during the late 9th and early 10th centuries. Working at the Preslav Literary School during the reigns of Boris I and Simeon I, he was a key figure in medieval Bulgarian letters. His extensive literary output, which combined original compositions with translations of Byzantine texts, demonstrates a profound mastery of the Greek language. While his exact biographical details remain uncertain, he is remembered as a significant intellectual of his era.
Literary work
His most notable achievement is the Shestodnev (Hexameron), a compilation containing original writings and translations of Byzantine authors, such as Basil the Great. This work provides rare historical insights into the social structure and royal court of the Bulgarian Empire under Simeon I. Additionally, he translated the theological writings of John of Damascus, specifically On Orthodox Christianity, around the year 895.
Veneration
Recognized as a saint, he is commemorated within the Orthodox tradition. The Russian Orthodox Church celebrates his feast day on August 13, though some historical manuscripts suggest an alternative date of February 13. Some scholars debate whether his title, the Exarch, indicated he held the rank of Archbishop or referred to a different position.
