Cercyon of Eleusis

According to the different versions, Cercyon was the son of: (1) Poseidon and one of the daughters of Amphictyon, and accordingly half-brother of Triptolemus[1] or (2) Branchus and the nymph (or naiad) Argiope[2] and finally of Hephaestus.

[3] He had one child, Alope[4][5] but in the Suda, Cercyon was called the father of a certain Ekphantos, ancestor of the epic poet Musaeus (Cercyon-Ekphantos-Euphemus-Antiphemos-Musaeus).

The first gave it without the garments, and when strife rose between them, the one who had taken the child demanded signs it was free-born, but the other refused to give them, they came to King Cercyon and presented their arguments.

In his fifth labour, journeying from Troezen, Theseus eventually beat and killed Cercyon when he lifted him up and dashed him to the ground.

[12] In the account of Bacchylides, he alludes to the event when saying "Theseus has closed the wrestling school of Cercyon".
