Corycian Cave

The Corycian Cave is located in central Greece on the southern slopes of Mount Parnassus, in Parnassus National Park, which is situated north of Delphi. The Corycian Cave has been a sacred space since the Neolithic era, and its name comes from the mythological nature spirits the Corycian nymphs, which were depicted as looking like beautiful maidens and were said to inhabit the cave. More specifically it is named after the nymph Corycia; however, its name etymologically derives from korykos, "knapsack". A modern name for the cave in some references is Sarantavli, meaning "forty rooms" due to the fact that the cave has many caverns that go deep into Mt. Parnassus. The Corycian Cave was used primarily as a place of worship for Pan, the god of the wild, as well as the Corycian nymphs, Zeus, and is also thought to be the ritual home of Dionysus. Also in mythology, Zeus was imprisoned in the Corycian Cave by the monster Typhon.
