Masters, as Zissos points out, argues that the Sibyl's commands to bury Misenus and find the Golden Bough are inverted and compacted in Lucan: Erichtho needs a body—not buried—but rather retrieved. Many other parallels and inversions abound, including: the difference of opinions about the ease of getting what is sought from the underworld (the Sibyl says only the initial descent to the underworld will be easy, whereas Erichtho says necromancy is simple), the opposing manner in which those seeking information from the underworld are described (the Sibyl urges Aeneas to be courageous, whereas Erichtho criticizes Sextus Pompeius for being cowardly), and the inverted manner in which the supernatural rites proceed (the Sibyl sends Aeneas underground to gain knowledge, whereas Erichtho conjures a spirit up out of the ground to learn the future).
