Good places for storing
organs whilst one waits to pass to next life, if you were an
Egyptian, being
mummified.
Canopic jars were made of clay. During the
mummification process, the brains and guts of the deceased were transfered to the jars. The heart was the exception. It had to remainin the body of the mummy, for its soul to be properly weighed on the scales of
Ma'at.
