This series in the field of classics grew out of Project Theophrastus, an international undertaking whose goal is to collect, edit, and comment on the fragments of Theophrastus, Greek philosopher, Aristotle’s pupil and second head of the Peripatetic School. Contributions are by international experts, and each volume will have a particular focus. Volume I is devoted to Arius Didymus, court philosopher to Caesar Augustus and author of an extensive survey of Stoic and Peripatetic ethics. Volumes II and III will concentrate on Theophrastus and disseminate knowledge gained through work on the project. Volume IV will focus on Cicero and his knowledge of Hellenistic philosophy.
