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.
Xenia (Greek)
The Greek god Zeus is sometimes called Zeus Xenios in his role as a protector of guests. He thus embodied the religious obligation to be hospitable to travelers. Theoxeny or theoxenia is a theme in Greek mythology in which human beings demonstrate their virtue or piety by extending hospitality to a humble stranger "(xenos)", who turns out to be a disguised deity "(theos)" with the capacity to bestow rewards. These stories caution mortals that any guest should be treated as if potentially a disguised divinity and help establish the idea of "xenia" as a fundamental Greek custom. The term "theoxenia" also covered entertaining among the gods themselves, a popular subject in classical art, which was revived at the Renaissance in works depicting a Feast of the Gods.
