"Believing in the menace of the tempter, who helps him make a victim out of the sickly Prince Joasaf, the wise vizier Varlaam decides to intervene and save the young heir from the abyss of ignorance. This ancient Greek legend is embodied in the book "Barlaam and Joasaf" by St. John Damascene, giving the reader the opportunity to immerse himself in the world spiritual search and religious penetration."
