The lost plays of the Greek tragic poets are preserved in fragmentary form only. This volume presents the texts of their most interesting and substantial parts with full apparatus criticus. For the larger part it consists of fragments of Euripides, including the extensive remains of such plays as Antiope, Erechtheus, Phaethon, and Hypsipyle. Also included are fragments from twelve plays of Aeschylus and thirteen of Sophocles --- there is a complete text of the extensive papyrus fragments of Ichneutae --- and a small number of fragments by minor tragedians. All papyri have been examined afresh, and the texts printed in this edition contain many novelties. This edition, which forms a supplement to Professor Diggle's Euripidis Fabulae (OCT 1981-94) makes accessible for the first time in a single collection a body of material which is of the highest interest for students of Greek tragedy.
