A trade deficit occurs when a countryâs imports exceed its exports for a given period of time.
The purpose of the four canopic jars in ancient Egypt was to store and preserve the inner organs of the human body. Each canopic jar was protected by one of the four sonsâ of the god Horus and each jar was in the shape of the protector godâs head. The organs were removed during mummification, separately mummified, and wrapped before being placed inside separate jars.
The design of canopic jars changed over time. 1  The oldest date from the Eleventh or the Twelfth dynasty, and are made of stone or wood. The last jars date from the New Kingdom. In the Old Kingdom the jars had plain lids, though by the First Intermediate Period jars with human heads (assumed to represent the dead) began to appear.
