Greek mythology is the body of myths and teachings that belong to the ancient greeks, concerning their gods and heroes, the nature of the world, and the origins and significance of their own cult and ritual practices. It was a part of the religion in ancient greece. The greeks were polytheistic in their religious beliefs. Polytheistic means they believed in and worshiped many different gods. Modern scholars refer to and study the myths in an attempt to shed light on the religious and political institutions of ancient greece and its civilization, and to gain understanding of the nature of myth-making itself.

Furthermore, osiris was associated with the kings of egypt because the egyptians believed he was a king himself. The ancient egyptians could trace their kings back, one by one, to a time when the gods were believed to have ruled the land in person. Osiris was the third or fourth successor to the egyptian throne after creation, and the egyptians believed that osiris's connection with kingship is what allowed their kings to be reborn in a way themselves. He was also said to be physically enormous – almost 15 and a half feet according to some sources – which was said to have aided him in his military campaigns.
