More than forty years have passed since the publication of volume II of James Diggle's Oxford Classical Text of Euripides (1981). That volume was the first to be published of the three volumes of the OCT edition: volumes I and III followed in 1984 and 1994. This second edition has been re-typeset to correct some deficiencies in the first edition, and updated to take into account developments in scholarship. Since the plays contained in volume II are transmitted in a much more corrupt state than most of those in the other volumes and pose far more problems, the editor has rethought every problem afresh, introducing many changes in the text. This volume includes an entirely new apparatus criticus, reassigning a large number of conjectures to their correct authors, and incorporating many new proposals. Re-examination of the manuscripts by autopsy has provided fuller and more precise details of manuscript readings, in particular of readings introduced by the hands which corrected manuscripts L and P. This new edition also incorporates the evidence of newly published papyri.
