MELIA was the Okeanis Nymph ancestress of the royal families of Argos, Sikyon and Thebes.
She was probably the Naiad of the Ismenian Spring of Thebes in Boiotia. By her brother Inakhos, god of the Argive River of the same name, she had two sons: Phoroneus, the first king of Argos and the southern Peloponesse, and Aigialeus first king of Boiotia and the northern Peloponnese (Akhaia, Sikyon and Korinthos). Their descendants (through Io) returned to Greece from the Egypt and Phoenicia after the Great Deluge, Danaus founding the city of Argos in the Peloponnese, and Kadmos the city of Thebes in Boiotia.
Melia, in her role as the Nymphe of the Ismenian Spring of Thebes, appears in a different guise as Melia, a Nymphe loved by Apollon, and Ismene.
