Korneli Kekelidze (1879-1962) belongs to those outstanding Georgian scholars, who added world value and prestige to the science of his homeland. A researcher of high academicism, wide scientific range, and multifaceted interests has left a deep and fruitful mark in the vast virgin soil of research in Georgian philology, Georgian-Byzantine and Georgian-Persian relations, and Christian ecclesiology. His works still maintain a scientific resonance. The crown of Korneli Kekelidze's versatile scientific creativity is his fundamental, monographic work the History of Old Georgian Literature published several times in Tbilisi, Georgia. The work is entirely based on original sources. It discusses centuries-old Georgian literature against the background of Christian peoples of the East, especially Byzantine writings which enhances its Georgian and general scientific value. The present book is a patrological part of the extensive, monumental work. It analyzes Georgian ecclesiastical literature of the 5th-18th centuries, the path of its development, and periods. The life of old Georgian writers, their original or translated works will easily convince the readers that they are dealing with an old, national cultural-historical creative work which according to Korneli Kekelidze, “has a rare match with other literature in terms of the number of manuscripts and literary monuments, preservation and value.” Thus, the book is a good gift for English-speaking readers interested in the history of culture in general, especially for scholars and students who aim to study and research the life and culture of Eastern Christian nations including the Georgian nation.
