While ancient Egyptians had no conception of religion as a distinct sphere of life, modern scholars have identified a wide range of Egyptian beliefs and practices relating to the divine. Egyptian religion can be traced back to predynastic times, and it developed continuously until the decline of temple religion in the Roman Period. Three mythic cycles are key to its understanding: the creation of the world, and the related solar cycle, which describe the origin and maintenance of the world, and the Osiris cycle, which provides a justification for the human institutions of kingship and funerary rites. Egyptian religion may be seen as being centered on its temples, which functioned both as sites for the worship of the resident gods and the elaboration of their theologies and as important economic and political centers. In addition to gods, three other categories of divine beings played important roles in Egyptian religious practice: kings, sacred and divine animals, and the dead. The king was intimately involved in the temple religion, as the mediator between the divine and human spheres, the patron of the temples, and the beneficiary of his own rituals, while divine and sacred animals seem to have been likewise understood as living embodiments of divine power. Death was understood through a range of metaphors, to which the ritual response was to link the deceased to one or more of the cosmic cycles through practices aimed at translating them into the divine sphere and thus ensuring their continued existence. As with all aspects of the religion, these rituals changed over time but show remarkable consistency throughout recorded history. Alongside these rituals centered on temple, royal, and funerary cults, a number of personal religious practices have been reconstructed as well as one major break in continuity, the “Amarna Revolution,” in which the ruling king seems to have briefly instituted a form of monotheism.
