But the Corycian cave exceeds in size those I have mentioned, and it is possible to make one's way through the greater part of it even without lights. The roof stands at a sufficient height from the floor, and water, rising in part from springs but still more dripping from the roof, has made clearly visible the marks of drops on the floor throughout the cave. The dwellers around Parnassus
believe it to be sacred to the Corycian nymphs, and especially to Pan. From the Corycian cave it is difficult even for an active walker to reach the heights of Parnassus
. The heights are above the clouds, and the Thyiad women rave there in honor of Dionysus and Apollo.
