What role do the witches play in Goethe's Faust?

The apes and the witch serve as comic relief and spectacle in the play. Scholars of Goethe’s play generally agree that there is little significance in the apes’ language or the witch’s incantations other than to provide a dose of nonsense and entertainment into the play. Both the apes and the witch perform a ritual of perversion, first crowning Mephistopheles as a ruler or king of their underworld and secondly providing Faust with a potion that symbolizes a dark Eucharist. The witch even calls Mephistopheles “Satan,” though he corrects her, saying that just as humanity has evolved past all of their superstitions, so too have the spirits of evil evolved into forms less noticeable.
