This volume forms the second part of the three-volume commentary on the fragments of Diphilus, who belongs to the prominent triad of the poets of New Comedy alongside Menander and Philemon. The present volume comprises the text and an English translation of the fragments of twenty-two plays of Diphilus, followed by a full-scale (philological, thematic, literary, interpretative, historical) commentary that also yields insight into the reception of Diphilan comedy in Roman theatre. This in-depth study of the Diphilan techniques of verbal humour and performance aims at shedding light on the dramatist's distinctive place in the comic tradition, as well as showcasing a degree of variation in the overall image of the production of new comedy.
