In Greek mythology, Arne (/ˈɑrniː/; Ancient Greek: Ἄρνη) or Melanippe (/mɛləˈnɪpiː/; Μελανίππη) was a daughter of Aeolus and Melanippe (also Hippe or Euippe), daughter of Chiron. She was born as a foal as her mother had been transformed into a horse as a disguise, but was returned to the human form and renamed Arne. Aeolus entrusted her to the care of one Desmontes, however Poseidon fathered Aeolus and Boeotus with her while he was in the form of a bull. Enraged, Desmontes entombed and blinded her and placed her twin sons on Mount Pelion. She was later rescued by her sons and married king Metapontus of Icaria, and Poseidon restored her vision.
Through Boeotus, she was the ancestress of the Boeotians. A city named after her was recorded in the Iliad's Catalogue of Ships which has been tentatively identified with the ruins of Gla.
