Gigineishvili's study is a comprehensive exposition of the philosophical system of twelfth-century Georgian Christian Neoplatonist philosopher Ioane Petritsi. Petritsi translated and commented Proclus' Elements of Theology - the first complete translation of this treatise ever made. The translation needed the creation of a philosophic language-a medium for transmitting the extravagant philosophic ideas into Georgian-which Petritsi had effectively achieved. Petritsi both explains intricacies of Proclus' thought and tries to prove the basic affinity between the Platonic and the Biblical traditions. Gigineishvili exposes the entire system of Petritsi's thought on a background of ideas of Proclus, other Neoplatonists, and of the Church Fathers.
