Ismenis

In GREEK mythology, Ismenis was a Naiad nymph, one of the daughters of the Boeotian river god Ismenus: Ismenis is a patronymic rather than a given name. In Statius' Thebaid, Ismenis was the mother, by Pan, of Crenaeus, a defender of Thebes against the Seven. When Crenaeus was killed by Hippomedon whom he had challenged to single combat, Ismenis searched for his body which was carried away by the flow of River Ismenus, and, upon finding it, lamented her son's fate.[1]
