Eurypylus of Cyrene
In Greek mythology, Eurypylus was a son of Poseidon and the Pleiad Celaeno, and together with his brother Lycus, they ruled over the Fortunate Islands. Others state that Eurypylus was a king of Cyrene, and note that the brothers were also referred to as Eurytus and Lycaon. Eurypylus married Sterope, a daughter of Helios and had two sons, Lycaon and Leucippus. Triton assumed his shape when he encountered the Argonauts in Libya. This Eurypylus must not be confused with another son of Poseidon named Eurypylus, king of Cos.
