Osiris is an ancient Egyptian god associated with the afterlife, resurrection, and fertility. He is often depicted as a mummified man wearing a white crown, symbolizing his role as the ruler of the underworld. Osiris is the husband of Isis and the father of Horus, and he is central to the myth of death and rebirth in Egyptian mythology. Osiris was believed to have been murdered by his brother Set, who was the god of chaos. After his death, Isis resurrected him, allowing him to become the king of the underworld. This story symbolizes the cycle of life, death, and rebirth, which was crucial to ancient Egyptian beliefs about the afterlife.
