In Greek mythology, Eumolpus was the son of Poseidon, god of the sea, and Chione, goddess of snow. When Chione got impregnated by Poseidon, she was afraid of the reaction of her father, Boreas, so she threw the baby into the sea. Poseidon took Eumolpus and went to Ethiopia, where his daughter Benthesikyme lived. She took Eumolpus under her protection, and when he grew up, he married one of Benthesikyme's daughters. However, he later fell in love with one of her sisters and was banished. He eventually arrived in Eleusis, where he became a priest of the goddess Demeter and also co-founded the Eleusinian Mysteries. Afterwards, he received the throne of Thrace from King Tegyrios.
