Shakespeare's Comedy of Errors is a madcap romp of mistakings and misadventures, wrapping together two Plautine comedies sauced with Scripture and Renaissance poetry. Yet the tangled web of estranged family that Shakespeare weaves holds significant differences from any of his originals, pointing to ideas about family and marriage that Shakespeare no doubt held, and was to develop further in later works.Plautus' Menaechmi yields a basic framework for Shakespeare's plot: two long-separated brothers mistaken for one another. Yet Plautus' two brothers differ markedly in attitude: one is gay, generous, and fun-loving, the other shrewd, calculating, and cynical. Shakespeare's Antipholi seem as confused as their Menaechmi relations, but more interchangeable in general temperament. Plautus' Amphitryon provides the idea of doubling servants as well as masters, but these are duplicates by divine action: one set are disguised gods fully aware of the situation, the other confused mortals.

One of the main themes of Shakespearean comedy is that of the new community: thus the stereotypical round of marriages that is a given for almost any comic Act V.
