James Diggle's groundbreaking studies on the text of Euripides, culminating in his new edition of the complete plays in the Oxford Classical Texts series, have won him a wide reputation as one of the leading authorities on Euripides. This collection comprises forty-one papers and reviews (including five previously unpublished papers) designed as a companion to the Oxford Text. The published papers and reviews have been lightly revised and updated and equipped with copious cross-references. There are full indexes. The collection not only offers a commentary on an extensive range of problematic passages in the plays; it also provides an up-to-date grammar of Euripidean usage--linguistic, stylistic, and metrical--and deals with many aspects of the manuscript tradition.
