What natural order was Erichtho accused of undermining?
Lucan depicts Sextus Pompeius, the doomed son of Pompey the Great, as convinced "the gods of heaven knew too little" and awaiting the Battle of Pharsalus by consulting with the Thessalian witch Erichtho, who practices necromancy and inhabits deserted graves, feeding on rotting corpses. Erichtho, it is said, can arrest "the rotation of the heavens and the flow of rivers" and make "austere old men blaze with illicit passions". She and her clients are portrayed as undermining the natural order of gods, mankind and destiny. A female foreigner from Thessaly, notorious for witchcraft, Erichtho is the stereotypical witch of Latin literature, along with Horace's Canidia.
