GERYONEUS A son of Chrysaor and the Okeanid nymph Kallirhoe. He possessed the bodies of three men, the heads of three men, three pairs of legs and six arms. He was gigantic in size, heavily armed, powerful and winged. He was the lord of immense flocks of cattle. It was these kine that Hercules, as part of his Twelve Labours, had to capture and take away, which he did after fighting with and killing Geryoneus.
