The Comedy of Errors is one of William Shakespeare's early plays. It is his shortest and one of his most farcical comedies, with a major part of the humour coming from slapstick and mistaken identity, in addition to puns and word play. Because the law forbids merchants from Syracuse to enter Ephesus, elderly Syracusian trader Egeon faces execution when he is discovered in the city. He can only escape by paying a fine of a thousand marks. He tells his sad story to Solinus, Duke of Ephesus. In his youth, Egeon married and had twin sons. On the same day, a poor woman without a job also gave birth to twin boys, and he purchased these as slaves to his sons.
