Melanthea

In Greek mythology, Melantheia or Melanthea (Ancient Greek: Μελανθείας) was the daughter of the river-god Alpheus, and thus she can be counted as a naiad. Melanthea bore to Poseidon, Eirene whom the earlier name of Calaurea was called after her (Eirenê). Later on, this island was named Anthedonia and Hypereia by the companions of the siblings Anthus and Hypera.
