Mount Parnassus is a mountain of limestone in central Greece that towers above Delphi, north of the Gulf of Corinth, and offers scenic views of the surrounding olive groves and countryside. According to Greek mythology, this mountain was sacred to Dionysus and the Dionysian mysteries; it was also sacred to Apollo and the Corycian nymphs, and it was the home of the Muses. The mountain was also favored by the Dorians. It is suggested that the name derives from parnassas, the possessive adjective of the Luwian word parna meaning house, or specifically temple, so the name effectively means the mountain of the house of the god.

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
