Comedy of Errors, The, play by English playwright and poet William Shakespeare, written around 1592. The play exemplifies the common Elizabethan practice of adapting classical comedy to the contemporary stage: The plot is loosely based on the play Menaechmi of Roman dramatist Plautus, and it also borrows from his Amphitrus. The story revolves around the twins Antipholus of Ephesus and Antipholus of Syracuse, their parents, and the family’s two servants, Dromio of Ephesus and Dromio of Syracuse, who are also twins. A shipwreck separates the family into two groups, leaving the mother with one son and one servant and the father with the other pair. The 'errors' of the play’s title are caused by repeated instances of mistaken identity. These are finally dispelled when the two pairs of twins meet, are properly recognized, and rejoin the other members of their families.
