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 ten ourea, Aitna, Athos, Helikon, Kithairon, Nysos, Olympus I, Olympus II (Mount Uludağ) 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.
