Thesmophoriazusae is perhaps the funniest of all Aristophanes’ comedies, in which gender inversion and transvestism run riot as the tragic dramatist Euripides is made to take part in a hilarious spoof on some of his own favourite plot lines, with his own life at stake as well as that of his loyal and much-put-upon old relative. This edition offers a freshly constituted text making use of papyri published within the last few years, together with the first fully annotated English translation there has been of this play.
