Who was considered the god of death and the underworld in Egyptian mythology?

In Egyptian mythology, Osiris is recognized as the god of death and the underworld. He plays a crucial role in the beliefs surrounding the afterlife and resurrection. Osiris is often depicted as a green-skinned deity, symbolizing fertility and new life, which aligns with the themes of rebirth following death. He is associated with the cycle of life, death, and the regeneration of crops, embodying the duality of death as a part of the continuous life cycle.

Osiris also holds the title of the judge of the dead, determining the fate of souls in the afterlife. His myth includes a narrative where he is murdered by his brother Seth, later resurrected by his wife Isis, which further cements his status as a vital figure in the afterlife beliefs of ancient Egyptians. This connection to both death and renewed life makes Osiris an essential god within the context of Egyptian spirituality and mythology.
