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.
Canopic jars of the Old Kingdom were rarely inscribed, and had a plain lid. In the Middle Kingdom inscriptions became more usual, and the lids were often in the form of human heads. By the Nineteenth dynasty each of the four lids depicted one of the four sons of Horus, as guardians of the organs.
