Some myths convey the fact that the goddess Gaia was impregnated by the blood of the castrated sky-god Uranus. She subsequently bore a tribe of 100 giants which were customarily depicted as primitives with serpents instead of legs. They were possibly descended from the barbarian tribes of Thrace.
In this mosaic, the mythological scene shows the kneeling King of the Gigantes succumbing after being attacked by Hercules in the battle between the gods and the Gigantes. Very expensive ancient Roman glass tesserae were used in the plants to embellish the importance of the scene. A very similar mosaic to this one was found in the Villa Romana del Casale.
