Barlaam and Josaphat: A Tale from the Christian East

Originally published in 1966, the full Georgian text of the oldest version of this Christian version of this matchless classic of Oriental wisdom literature is made accessible to a wider readership in an English translation. Based on a unique manuscript preserved in the Greek Patriarchate at Jerusalem, this rendering should appeal to those interested in comparative religion, Buddhism, medieval Christianity, the history of monasticism and in the literature of the Georgians and other ancient nations of the former Soviet Union.
