Scholia to Pindar tell us that Alcyoneus lived on the isthmus of Thrace and that he had stolen his cattle from Helios, causing the Gigantomachy, (Schol. Pindar "Isthmian" 6.47) and that Alcyoneus, one of the Giants, attacked Heracles, not in Thrace but at the Isthmus of Corinth, while the hero was returning with the cattle of Geryon, and that this was according to Zeus' plan because the Giants were his enemies (Schol. Pindar "Nemean" 4.43). The cattle shown on the sixth century pots, might thus represent either Alcyoneus' cattle stolen from Helios, or Heracles' cattle taken from Geryon.
