Pericles, the young Prince (ruler) of Tyre in Phoenicia (Lebanon), hears the riddle, and instantly understands its meaning: Antiochus is engaged in an incestuous relationship with his daughter. If he reveals this truth, he will be killed, but if he answers incorrectly, he will also be killed. Pericles hints that he knows the answer, and asks for more time to think. Antiochus grants him forty days, and then sends an assassin after him. However, Pericles has fled the city in disgust.
