Eirene (daughter of Poseidon)

In Greek mythology, Eirene (Eirḗnē, ) or Irene, was a daughter of Poseidon and Melanthea, daughter of Alpheus. She gave her name to Eirene, a small island near the Peloponnese. The island was later called Anthedonia and Hypereia, but eventually received the name Calauria after Calaurus, who was also a son of Poseidon.
