Erichtho

In Roman literature, Erichtho is a legendary Thessalian witch. In the epic by the poet Lucan, "Pharsalia" (VI, 507—830), she summons a spirit to reveal to Pompey the Great's son, Sextus Pompeius, the outcome of the Battle of Pharsalus. She is also mentioned by Dante Aligheri in his "The Divine Comedy" ("Inferno": IX 23), where Virgil tells of having been compelled by her to descend into the deepest part of hell to bring back a spirit.

She is also a character in Johann Wolfgang von Goethe's "Faust", Part 2, Act 2: She is the first character to speak in the Classical Walpurgisnacht scene (II.1). Erichtho's speech to open that scene is the introduction of the Witches' High Sabbath. It immediately precedes the entrance of Mephistopheles, Faust, and Homunculus to the rites that result in Faust's Dream Life Sequence as a knight living in a castle with Helen of Troy (until the death of their child shatters the fantasy and Faust returns to the physical world for the conclusion of the play).
