||Of the Mountain
OREIOS was one of the mountain gods, probably that of Mount Othrys in Malis, central Greece. He was the father of Oxylos ("Thick with Forest") and Hamadryas ("Joined with Tree"), who in turn were the parents of the younger, tree-specific Hamadryad Nymphs.
|Presumably a son of GAIA like the other mountains
|OXYLOS, HAMADRYAS (Athenaeus 78b)
Athenaeus, Deipnosophistae 1. 78b (trans. Gullick) (Greek rhetorician C2nd to C3rd A.D.) :
"The Epic poet Pherenikos (Pherenicus), a Herakleto by birth, declares that the fig (Sykon) was named from Syke (Fig-Tree), the daughter of Oxylos (Beech-Tree); for Oxylos, son of Oreios (Mountain), married his sister Hamadryas (Plum Tree) and begot among others, Karya (Walnut-Tree), Balanos (Oak-Nut Tree), Kraneia (Cornel-Tree), Morea (Mulberry-Bush), Aigeiros (Poplar-Tree), Ptelea (Elm-Tree), Ampelos (Grape-Vine), and Syke (Fig-Tree); and these are called Nymphai Hamadryades, and from them many trees derive their names."
