Mount Parnassus is named after Parnassos, the son of the nymph Kleodora and the man Kleopompus. A city, of which Parnassos was leader, was flooded by torrential rains. The citizens ran from the flood, following wolves’ howling, up the mountain slope. There the survivors built another city, and called it Lykoreia, which in Greek means ‘the howling of the wolves’.
While Orpheus was living with his mother and his eight beautiful aunts on Parnassus, he met Apollo who was courting the laughing muse Thalia. Apollo became fond of Orpheus and gave him a little golden lyre, and taught him to play it. Orpheus’s mother taught him to make verses for singing. As the Oracle of Delphi was sacred to the god Apollo, so did the mountain itself become associated with Apollo.
According to some traditions, Parnassus was the site of the fountain Castalia and the home of the Muses; according to other traditions, that honour fell to Mount Helicon, another mountain in the same range. As the home of the Muses, Parnassus became known as the home of poetry, music, and learning.
Parnassus was also the home of Pegasus, the winged horse of Bellerophon.
