Horus is one of the most significant deities in ancient Egyptian religion, who was worshipped from at least the late Predynastic period through to Greco-Roman times. Different forms of Horus are recorded in history and these are treated as distinct gods by Egypt specialists. These various forms may possibly be different perceptions of the same multi-layered deity in which certain attributes or syncretic relationships are emphasized, not necessarily in opposition but complementary to one another, consistent with how the Ancient Egyptians viewed the multiple facets of reality. He was most often depicted as a falcon, most likely a lanner or peregrine, or as a man with a falcon head.
The earliest recorded form of Horus is the patron deity of Nekhen in Upper Egypt, who is the first known national god, specifically related to the king who in time came to be regarded as a manifestation of Horus in life and Osiris in death. The most commonly encountered family relationship describes Horus as the son of Isis and Osiris, and he plays a key role in the Osiris myth as Osiris's heir and the rival to Set, the murderer of Osiris. In another tradition Hathor is regarded as his mother and sometimes as his wife. Horus served many functions in the Egyptian pantheon, most notably being a god of the sky, war and hunting.
