Pholus was a Centaur who lived on Mount Pholoë. He was accidentally killed by Heracles after an argument over the wine that he had provided for his eminent guest.

His name perhaps derives from his home, pholeos, 'den', 'lair', or from such a place that he frequented or visited. Robert Graves thinks his name was originally 'Phobus' and that it therefore means 'fear' (like Phobos).
