As I was walking last week, a virtual hike through the land of the pyramids, the guide told us a story about how the Egyptian pharaoh's hearts were weighed in the afterlife. If they were lighter (or as light) than a feather, they proceeded, but if they were heavier, they were devoured.The ancient Egyptians believed that the heart recorded all of the good and bad deeds of a person’s life, and was needed for judgment in the afterlife. After a person died, the heart was weighed against the feather of Maat (goddess of truth and justice). The scales were watched by Anubis (the jackal-headed god of embalming) and the results recorded by Thoth (the ibis-headed god of writing). If a person had led a decent life, the heart balanced with the feather and the person was rendered worthy to live forever in paradise with Osiris. (Carnegie Museum of Natural History)
A heart as light as a feather. Hmmm, interesting concept.
