The volume contains contributions dedicated to the person and the work of Shalva Nutsubidze and his scholarly interests: the Christian Orient from the fifth to the seventh century, the Georgian eleventh century, the Neoplatonic philosopher Ioane Petritsi and his epoch and Shota Rustaveli and mediaeval Georgian culture. Among the articles are a new edition and translation of the original Georgian author ́s Preface to the lost Commentary on the Psalms by Ioane Petritsi and the editio princeps with an English translation of an epistle of Nicetas Stethatos (eleventh century), whose Greek original is lost. The traditions of Georgian mediaeval thought are considered in their historical context within the Byzantine Commonwealth and are traced in both philosophy and poetry.
