Geryon
The three-bodied guardian of the cattle on Erytheia.

Overview
Geryon lives on Erytheia beyond Ocean and is described as three bodies joined at the belly. His cattle are protected by a two-headed dog and a herdsman; Heracles overcomes those guards and then kills Geryon with an arrow when he comes to defend the herd near Mount Abas. The chapter locates the death within a contested taking rather than treating the expedition as automatically righteous.
