As Halirrhothios, the son of Posiedon and Nymph (which is a mythological spirit of nature imagined as a beautiful maiden inhabiting places) named Eurtye, was trying to harm Alkippe, Ares caught him and cut him. Poseidon had Ares tie Eurtye on the composite form of the Greek name Areios Payos translated " Ares Rock."(It is North-East of the Acropolis in Athens with the twelve gods presiding),and Ares was free.
