Porphyrion is named on a sixth-century BC black-figure
pyxis (Getty 82.AE.26), where he and the Giant
Enceladus oppose Zeus, Heracles and
Athena. He is also named on a late fifth-century BC red-figure cup from
Vulci (Berlin F2531), and a fifth-century BC red-figure
krater (Paris, Petit Palais 868), in both engaged in single combat with
Zeus, and a late sixth-century/early fifth-century fragmentary BC red-figure cup (British Museum E 47), where his opponent is lost. Porphyrion was probably named on the
Gigantomachy depicted on the north frieze of the
Siphnian Treasury at
Delphi (c. 525 BC), and he was one of the many Giants depicted on the second-century BC
Pergamon Altar Gigantomachy frieze, where he is shown fighting Zeus. ==Notes==
