Eleusis was a mythical hero after whom the city was named. He was the son of Hermes and the Oceanid Daeira, or of Ogygus, the mythological ruler of Boeotia or the first king of Attica. The 5th-century BC Greek epic poet Panyassis of Halicarnassus claimed that Eleusis was the father of Triptolemus with Demeter, who “came to him” or with Cothonea. According to the Latin author Gaius Julius Hyginus, when Demeter visited King Eleusis, she decided to make his son, Triptolemus, immortal. The goddess nurtured the boy with divine milk and buried him in the fire at night. His parents wondered at his miraculous growth, so Eleusis watched Demeter one evening and was horrified at the strange ritual. Demeter grew angry at his intervention and killed him. To compensate for the murder of his father, she gave Triptolemus her chariot yoked with dragons to spread agriculture. Triptolemus rode the chariot and sowed grain throughout the earth. Upon his return, Celeus was determined to kill him, but Demeter intervened and ordered Celeus to give his kingdom to Triptolemus, who named it after his father’s name.
