Ourea

The Ourea (Ancient Greek: Oὔρεα "mountains," plural of Oὔρος) were the Protogenoi or Daemons (spirits) of the mountains. Each mountain was said to have a god of their own. The Ourea were usually depicted as old men or women rising up from the mountain side.

Ourea
The Ourea were the sons of Gaia, which were created by her after she gave existence to Ouranós. As stated in the Theogony:

And Gaîa (Earth) first bore starry Ouranos (Heaven), equal to herself, to cover her on every side. And she brought forth long hills, graceful haunts of the goddess Nymphs who dwell amongst the glens of the hills.

The Ourea's cousins were the Nesoi, the spirits of island, which were broken off from the mountains and cast into the sea by Poseidon.

There were at least ten Ourea, the following is a list of known Ourea.
