Ourea

In Greek mythology, the Ourea (Οὔρεα, plural of Οὖρος, or 'Oûros') were the parthenogenetic offspring of Gaia (Earth), produced alongside Uranus (Sky), and Pontus (Sea).

According to Hesiod: "And [Gaia] brought forth long hills [Οὔρεα], graceful haunts of the goddess Nymphs who dwell amongst the glens of the hills."

Defined by Middle Liddell as from οὖρος "mountain, hill; mule; a guard."
