The ultimate horrors and powers of witchcraft are portrayed by Lucan in Book 6 of the Pharsalia, probably an effort to surpass his uncle. Before the decisive battle of Pharsalus (48 BCE), in which Julius Caesar defeats the forces of Pompey, the two armies had moved through Thessaly, the classical country of witchcraft. There, one of Pompey's sons consults the famous witch Erictho about the outcome of the upcoming confrontation. In Lucan's epic, Erictho is the most powerful witch, and is appropriately loathsome and disgusting. She can compel the lesser gods to serve her and cause them to shudder at her spells.[44]
