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. Soon afterwards, the family made a sea voyage, and was hit by a tempest. Egeon lashed himself to the main-mast with one son and one slave, while his wife was rescued by one boat, Egeon by another.
