The ancient Egyptians believed that there were many gods of the
dead. Osiris was the god of the underworld and prince of the
dead. Isis was his wife. Anubis was the jackal-headed god of
the embalmers. Horus was the god of the sky. Udjat, or the left
eye of Horus, was the protector of the dead. Thoth was the ibis-headed
god of the scribes. Another symbol of Thoth was the baboon.
A baboon was found by archaeologists mummified in a sitting position
so that it could write with ease.
In ancient Egypt it was believed that a person had a ba or soul of that was a bird with a human head. It was also believed that a person had an invisible twin called the ka. The ba kept in touch with the friends and family of the dead and the ka went back and forth from the other world where the gods and goddesses of the dead lived. The ka traveled to the other world on a boat. Small boats were put in the tombs to provide transportation for the ka. Some boats had sails for going upstream and others had rowers for going downstream. If the ba and ka could not find and recognize the body, the person could not live forever. The body was mummified so that it could be recognized by the ba and ka. The ba and ka lived in the body of the person until death, and then they lived in the tomb with the body. When a pharaoh died he turned into a god.
In order to live forever a person had to be honest. Anubis weighed
the heart against the feather of truth to see if the person was
honest. If the heart weighed more than the feather of truth it
meant that the person was dishonest. If the person was dishonest
his or her heart would be eaten by the devourer, a monster that
was part alligator, part cheetah, and part lion. The person
whose heart was eaten by the devourer would cease to exist and
cease ever to have existed. The results were recorded by the
ibis-headed god of the scribes, Thoth.
