Koryun, an early 5th-century Armenian scholar and cleric, holds a unique place in Armenian literary and ecclesiastical history as the first known biographer in Armenian literature. He is most renowned for authoring the “Life of Mashtots” (Vark Mashtotsi), a foundational work that provides invaluable insight into the creation of the Armenian alphabet and the life of its inventor, Saint Mesrop Mashtots.
Koryun was among the closest disciples of Mesrop Mashtots and was deeply involved in his teacher’s educational and missionary efforts. He was educated in Armenia and later sent to Byzantium for advanced studies, reflecting the intellectual ambitions of the Armenian Church during the Golden Age of Armenian literature. After returning from his studies, Koryun played a key role in spreading Christianity and literacy throughout Greater Armenia and the surrounding regions, including Georgia and Caucasian Albania.

As an author, Koryun’s writing is characterized by vivid narrative, emotional intensity, and deep reverence for Mashtots. His biography of Mashtots not only chronicles the invention of the Armenian script but also highlights the broader cultural and theological transformations of early Christian Armenia. Through his work, historians gain access to a contemporary witness of one of the most transformative periods in Armenian history.
Later in life, Koryun was appointed bishop of Georgia (Iberia), where he continued to promote Christian teaching and Armenian liturgical traditions. His contributions have earned him a lasting place among the revered figures of Armenian scholarship, and his Vark Mashtotsi remains a cornerstone of early medieval Armenian literature.
Koryun’s legacy endures as a pioneer of Armenian biographical writing and as one of the most faithful chroniclers of Armenia’s cultural awakening in the 5th century.
