In this volume, Eduard Sachau (1845-1930) published for the first time a number of texts translated from Greek into Syriac on the basis of manuscripts from the British Museum: Lucian’s On Slander; Themistius’ On Virtue (not extant in Greek) and On Friendship (not complete in Greek); (ps.-)Plato’s Definitions and Charge to his Disciple; The Sayings of Theono the Pythagorean; Sayings of the Philosophers on the Soul; The Sayings of Menander; The Life of Secundus the Silent Philosopher; and fragments of Galen’s Ars Medica and On the Powers of Foods. The appendix contains short texts that are related to, but not translated from, Greek texts, namely astronomical fragments from Sergius of Reshaina and Severus Sebokt. The texts are given in Syriac and includes a critical apparatus. This volume is foundational for the study of the transmission of Greek literature into Syriac.
