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.
Henotheism
While Greek and Roman religion began as polytheism, during the Classical period, under the influence of philosophy, differing conceptions emerged. Often Zeus (or Jupiter) was considered the supreme, all-powerful and all-knowing, king and father of the Olympian gods. According to Maijastina Kahlos "monotheism was pervasive in the educated circles in Late Antiquity" and "all divinities were interpreted as aspects, particles or epithets of one supreme God". Maximus Tyrius (2nd century A.D.) stated: "In such a mighty contest, sedition and discord, you will see one according law and assertion in all the earth, that there is one god, the king and father of all things, and many gods, sons of god, ruling together with him."
