Ochs' Surplice is based on the mythological Gorgon, a terrifying female creature. It derives from the Greek word gorgós, which means "dreadful." While descriptions of Gorgons vary across Greek literature, the term commonly refers to any of three sisters who had hair of living, venomous snakes, and a horrifying visage that turned those who beheld it to stone. Mythology holds that the three original sisters were once normal women, who had been changed into monsters after the defilement of Athena's temple. Traditionally, while two of the Gorgons were immortal, Stheno and Euryale, their sister Medusa was not, and was slain by the mythical hero Perseus. In Ovid's Aeneid, the hero Aeneas encounters the ghost of Medusa when he first enters the underworld.
