In Greek mythology, the Ourea (Ancient Greek: Oὔρεα "mountains," plural of Oὖρος) were progeny of Gaia, members of the Greek primordial deities, who were the first-born elemental gods and goddesses. According to Hesiod:
The nine ourea, Aitna, Athos, Helikon, Kithairon, Nysos, Olympus, Oreios, Parnes, and Tmolus, like Uranus, and Pontus, were parthenogenetic offspring of Gaia alone. The Greeks rarely personified an individual mountain; an exception might be Tmolus, both a king and a mountain in Lydia. Each mountain was said to have its own local nymph, an oread.
