SHEDU
The lamassu (SHEDU) is a celestial being from ancient Mesopotamian religion bearing a human head, bull's body, sometimes with the horns and the ears of a bull, and wings. It appears frequently in Mesopotamian art. The lamassu and shedu were household protective spirits of the common Babylonian people, becoming associated later as royal protectors, were placed as sentinels at the entrances. The Akkadians associated the god Papsukkal with lamassu and the god Išum with shedu.
To protect houses, the lamassu were engraved in clay tablets, which were then buried under the door's threshold. They were often placed as a pair at the entrance of palaces. At the entrance of cities, they were sculpted in colossal size, and placed as a pair, one at each side of the door of the city, that generally had doors in the surrounding wall, each one looking towards one of the cardinal points.
The ancient Jewish people were influenced by the iconography of Assyrian culture. The prophet Ezekiel wrote about a fantastic being made up of aspects of a human being, a lion, an eagle and a bull. Later, in the early Christian period, the four Gospels were ascribed to each of
these components. When it was depicted in art, this image was called the Tetramorph.
