In Greek mythology, Porphyrion was one of the Gigantes (Giants), who according to Hesiod, were the offspring of Gaia, born from the blood that fell when Uranus (Sky) was castrated by their son Cronus. In some other versions of the myth, the Gigantes were born of Gaia and Tartarus.

In Greek and Roman mythology, the Giants, also called Gigantes, were a race of great strength and aggression, though not necessarily of great size. They were known for the Gigantomachy, their battle with the Olympian gods. According to Hesiod, the Giants were the offspring of Gaia (Earth), born from the blood that fell when Uranus (Sky) was castrated by his Titan son Cronus.
