Demophon | King of Athens

Demophon (also Demophon, Demiphon or Damophon; Greek: Δημοφῶν) was, in Greek mythology, a king of Athens, son of Theseus and Phaedra and half-brother of Acamas. He fought in the Trojan War, and was one of the warriors who hid inside the Trojan Horse.

In Euripides' play The Heracles, Demophonus granted refuge in Athens to the sons of Heracles, who were fleeing from Eurystheus. Faced with an impending attack by the latter, an oracle predicted to Demophon that he would emerge victorious from the conflict only if a noble virgin were sacrificed to Persephone.

Macaria, daughter of Heracles, offered herself for sacrifice, and a water spring, the 'Macaria Fountain,' was named after her.

Demophon married Philis, daughter of Lycurgus, king of Thrace, when he stopped in that region during his return journey after the Trojan War. He abandoned her, however, when he returned to Athens; in one version, she is said to have killed herself when she saw that he would no longer return for her, while others tell that she would have made him fall on his own sword and die.
