LESSON 3 · Mysteries of the Nile
Inside the Embalmer's Workshop
The heart was the one organ embalmers left in the body. Egyptians believed it was the seat of intelligence. During the afterlife judgment, Anubis weighed it against the feather of Ma'at. A heart heavier than the feather meant a wicked life, and the monster Ammit would devour it.

This single belief shaped an entire civilization's morality. Modern science has learned remarkable things from mummies, including evidence of heart disease and cancer over three thousand years old.
