In Shakespeare’s The Comedy of Errors, Egeon is the Syracusan merchant sentenced to death at the beginning of the play.
Egeon has entered Ephesus despite a law forbidding merchants from Syracuse to do so. When he is discovered, Duke Solinus explains that Egeon must either pay a thousand marks or face execution. Egeon cannot immediately produce the money, so the Duke allows him one day to find it.
Before the sentence can be carried out, Egeon tells the story of a shipwreck that separated him from his wife, one of his twin sons, and one of the twin servants he had acquired for his children. His surviving son, Antipholus of Syracuse, has come to Ephesus searching for the missing family members, unknowingly triggering the play’s chain of mistaken identities.
Solinus is the Duke of Ephesus who imposes the judgment, not the condemned merchant. Antipholus and Dromio are the twin pairs whose confusion drives the comedy. Egeon’s danger is eventually resolved when the separated family is reunited.
