The Corycian Cave is located on the slopes of Mount Parnassus, in Greece. In the mythology of the area, 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". This cave was sacred to the Corycian Nymphs and the Muses, and a place of worship for Pan.
