In Greek mythology, Geryon, son of Chrysaor and Callirrhoe, the grandson of Medusa and the nephew of Pegasus, was a fearsome giant who dwelt on the island Erytheia of the mythic Hesperides in the far west of the Mediterranean. A more literal-minded later generation of Greeks associated the region with Tartessos in southern Iberia. Geryon was often described as a monster with either three bodies and three heads, or three heads and one body, or three bodies and one head. He is commonly accepted as being mostly humanoid, with some distinguishing features and in mythology, famed for his cattle.

In Greek mythology, the Hesperides are the nymphs of evening and golden light of sunsets, who were the "Daughters of the Evening" or "Nymphs of the West". They were also called the Atlantides from their reputed father, Atlas.
