In Egyptian mythology, the god Anubis oversaw the weighing of the heart ceremony, which determined the fate of the deceased in the afterlife. This ritual involved weighing the heart against the feather of Ma'at, symbolizing truth and justice. A balanced scale indicated a pure heart, allowing the individual to enter the afterlife, while an unbalanced scale led to the heart being devoured by the monstrous Ammut. This ceremony reflects ancient Egyptian beliefs in the importance of morality and the significance of judgment after death.
