What is "menaechmi"

Menaechmi, a Latin-language play, is often considered Plautus' greatest play. The title is sometimes translated as The Brothers Menaechmus or The Two Menaechmuses.

The Menaechmi is a comedy about mistaken identity, involving a set of twins, Menaechmus of Epidamnus and Menaechmus of Syracuse. It incorporates various Roman stock characters including the parasite, the comic courtesan, the comic servant, the domineering wife, the doddering father-in-law and the quack doctor. As with most of Plautus' plays, much of the dialogue was sung.
