Coryphaea
The goddess who inhabits the summit of the mountain, a surname of Artemis, under which she had a temple on mount Coryphaeon, near Epidaurus. (Pausanias) It is also applied to designate the highest or supreme god, and is consequently given as an epithet to Zeus. (Pausanias ii)
From Smith's Dictionary of Greek and Roman Biography and MythologyFrom Description of Greece by Pausanias Book 2
[2.28.2] As you go up to Mount Coryphum you see by the road an olive tree called Twisted. It was Heracles who gave it this shape by bending it round with his hand, but I cannot say whether he set it to be a boundary mark against the Asinaeans in Argolis, since in no land, which has been depopulated, is it easy to discover the truth about the boundaries. On the Top of the mountain there is a sanctuary of Artemis Coryphaea (of the Peak), of which Telesilla1 made mention in an ode.
