Menaechmi is one of Plautus' liveliest and most entertaining comedies, the main inspiration for Shakespeare's The Comedy of Errors. Dr Gratwick's edition brings new light to bear on the interpretation of the play and on Plautus' place in the development of European comedy. Central to his treatment is the fact that Plautus was a dramatist who wrote to be heard rather than to be read. The various metres which he subtly and flexibly exploited for musical and dramatic effect are here explained in a way that challenges many received views but also offers the student practical assistance in grappling with the technical problems involved both on stage and in performance. The text has been newly constituted on the basis of a complete reappraisal of the manuscript tradition in the light of scholarship since the Renaissance.
