Ismenus in the context of "Pelagon"

In Greek mythology, Melia or Melie (Ancient Greek Μελία, Μελίη) was the name of several figures. The name Melia comes from μελία, the ancient Greek word for ash-tree. In the plural, the Meliae were a class of nymphs associated with trees, particularly ash-trees. There were several other nymphs (or possible nymphs) named Melia, not necessarily associated with trees, these include:

• Melia, a Theban cult figure, who was the mother of Tenerus and Ismenus, by Apollo. She was said to be a daughter of Oceanus.
• Melia, mother of Phoroneus and Aegialeus, by her brother Inachus, the Argive river-god. She was also said to be a daughter of Oceanus.
• Melia, an Oceanid and a Bithynian nymph, who was the mother, by Poseidon, of Amycus, king of the Bebryces.
• Melia, the mother by Silenus of Dolion, the eponym of the Doliones. This is according to the third-century BC poet and grammarian Alexander Aetolus, as reported by the late first-century BC-early first-century AD geographer Strabo.
• Melia, the mother by Apollo of Keos, the eponym of the island Keos, according to the third-century BC poet Callimachus.

Two other personages named Melia, are known from scholia citing the fifth-century BC mythographer Pherecydes:

In ancient Greek religion and mythology, Melia (Ancient Greek: Μελία), a daughter of the Titan Oceanus, was the consort of Apollo, and the mother, by Apollo, of the Theban hero and prophet Tenerus. She was also the mother (or sister) of Ismenus, god of the Theban river of the same name. Melia was an important cult figure at Thebes. She was worshipped at the Ismenion, the Temple of Apollo at Thebes, and was associated with a nearby spring.
