Macedonia (ancient kingdom)
The Classical Greek historians Herodotus and Thucydides reported the legend that the Macedonian kings of the Argead dynasty were descendants of Temenus, king of Argos, and could therefore claim the mythical Heracles as one of their ancestors as well as a direct lineage from Zeus, chief god of the Greek pantheon. Contradictory legends state that either Perdiccas I of Macedon or Caranus of Macedon were the founders of the Argead dynasty, with either five or eight kings before AmyntasI. The assertion that the Argeads descended from Temenus was accepted by the "Hellanodikai" authorities of the Ancient Olympic Games, permitting Alexander I of Macedon () to enter the competitions owing to his perceived Greek heritage. Little is known about the kingdom before the reign of AlexanderI's father Amyntas I of Macedon () during the Archaic period.
Prometheus the Fire-Bringer
Despite the paucity of direct evidence, Prometheus' foreshadowing of future events in the trilogy's first play suggests that the final play concerned itself with Prometheus' knowledge of a secret that could potentially lead to Zeus's downfall, and how the revelation of this secret leads to reconciliation between the Titan and Olympian. The secret is this: Thetis the Nereid, whom Zeus wants to take as a lover, is fated to bear a child greater than its father. Lying with her, then, would result in Zeus's being overthrown just as he had overthrown his own father, Cronus. During the course of the drama, Prometheus decides to warn Zeus about Thetis. Rather than lie with her, Zeus marries her off to the mortal Peleus, King of Aegina. The product of this union will indeed be a son greater than the father, namely Achilles, Greek hero of the Trojan War. Consequently, Zeus reconciles with Prometheus.
