In Ancient Egyptian mythology, the god of the afterlife is Osiris. He symbolizes resurrection and eternal life, playing a central role in the Egyptian belief system surrounding death and the afterlife. According to myth, Osiris was betrayed and killed by his brother Set, but his wife Isis resurrected him. This narrative reinforces concepts of rebirth and the cyclical nature of life and death. As the ruler of the underworld, Osiris presides over the judgement of souls, and his festivals and rites are integral to funerary practices in ancient Egyptian culture.
