Ioane Petritsi was a twelfth-century Georgian philosopher, a student of the Constantinopolian philosophic school run by Michael Psellus and, later, John Italus. After returning to his homeland, Georgia, Petritsi sought to initiate Neoplatonic studies at the Gelati monastic school established by the enlightened King David IV the Builder. To that end, Petritsi produced a translation and commentary on Proclus’ Elements of Theology, a comprehensive exposition of the entire Neoplatonic ontological system.

This was the first complete translation of the Elements of Theology, ca. 100 years earlier than the first Latin translation by William Moerbeke, commissioned by St. Thomas Aquinas. The translation required the creation of a philosophic language—a medium for transmitting the extravagant philosophic ideas into Georgian—which Petritsi effectively achieved. In his original commentaries, Petritsi both explains the intricacies of Proclus’ thought and tries to prove the basic affinity between the Platonic and the biblical traditions. The present volume exposes the entire system of Petritsi’s thought upon a background of ideas on Proclus, other Neoplatonists, and the Church Fathers.
