Athos (mythology)
In Greek mythology, Athos (; Ancient Greek: Ἄθως, pronounced [ˈatʰɔːs]) is the name of one of the Giants, and an enemy that Poseidon fought. He is best known for the creation of Mount Athos, a mountain and peninsula in Chalcidice, northern Greece, which is now an important centre of Eastern Orthodox monasticism. In Greek it is commonly called Άγιον Όρος, meaning 'Holy Mountain'.
