The preparation for the Afterlife in ancient Egypt was no small task. Not only did people need to live a righteous life, have their own tombs built by experts, overcome the Trial of the Dead, and learn the exact directions to the underworld. Their bodies also needed to be correctly mummified, including having their most precious organs carefully extracted and placed in four specific vessels that stood for each of the Four Sons of Horus, gods that had the important mission of preserving those organs for all eternity. These vessels are known as canopic jars.
