Antiochus is the king of Antioch and the engine of the play’s opening moral catastrophe. He appears in only one scene, yet his presence poisons the entire first act and sets Pericles on his long journey of dispossession and suffering. Antiochus has committed incest with his own daughter—a crime so monstrous that the play treats it as a rupture in the natural order itself. Rather than hide or repent this sin, he has constructed an elaborate defense: he created a riddle about the incest and made it the condition for any suitor who wishes to marry his daughter. The riddle’s answer is the incest itself, and Antiochus intends this as a death trap. Any man clever enough to solve it will know his secret; any man he suspects of knowing will be executed. The riddle is a perfect emblem of Antiochus’s corruption—it dresses up evil in the language of courtship and challenge, making obscenity seem like a game.
When Pericles arrives at Antioch to solve the riddle, Antiochus is initially gracious, even flattering. He describes his daughter in extravagant terms, praising her beauty as a gift from heaven itself. But the courtesy is a mask. Once Pericles solves the riddle and recognizes the incest, Antiochus’s true nature emerges. He does not defend or explain himself; instead, he simply decides that Pericles must die. He sends his assassin Thaliard after the prince with poison and gold, and swears that Pericles will never leave his reach alive. In this moment, Antiochus reveals the logic of tyranny: he will use all the power of his kingdom—law, violence, secrecy—to protect his secret shame. The play’s own moral vision judges him swiftly. After Pericles flees, Gower announces that Antiochus and his daughter are struck down by divine fire, their bodies burning so horribly that they reek, and their own former admirers refuse to bury them. Antiochus never appears again, but his sin—incest, secrecy, the weaponizing of riddles and court rituals to hide evil—haunts the play’s opening and justifies Pericles’ flight into years of wandering and loss.
