Discworld Wiki

Mephistopheles is an intelligent goat owned by, or rather accompanied by, Geoffrey Swivel. He appears in the final Discworld novel, The Shepherd's Crown.

Mephistopheles travels with Geoffrey to Lancre in the Ramtops, where Geoffrey hopes to become a witch. Prior to finding work with Tiffany Aching, Mephistopheles helps the pair pay their way by performing arithmetic in pubs for tips. Mephistopheles also has some degree of magic power. He uses this power in a demonstration with Granny Weatherwax's cat, You, after which the two seem to have a mutual respect for each other.

At the end of the book, Mephistopheles remains in Lancre with Geoffrey as his witch's familiar.


Unfortunately, Sir Terry passed away prior to the publication of The Shepherd's Crown. Many fans think that Geoffrey and Mephistopheles would have appeared in future Discworld novels, where we may have learned more about the goat. Theories include the possibility that Mephistopheles is some kind of demon or a human trapped in a goat's body. In Roundworld German myth, Mephistopheles is the name of a demon lord who acts as the Devil's agent in the deal which Faust makes with the devil - Faust gets unlimited knowledge and endless worldly pleasures from the demon in exchange for his mortal soul.
