Model of a House ca. 1750-1700 B.C. Middle Kingdom At Rifa in middle Egypt, the British excavator William Flinders Petrie found clay models of houses such as this placed near burials in such a way that he concluded they had been placed above the burials. He called them "soul houses." At other sites such as Thebes, oval clay trays have been found that include sometimes rough reproductions of huts and always little offerings modelled in clay. These trays were placed in and at the entrances to tombs. Most of the models have a kind of spout at the front through which libation water could flow into the ground. This model from Rifa of the "soul house" type represents a house with a three-columned portico behind a walled courtyard; in front of the courtyard a libation spout is partly preserved. A stairway on the right gives access to the roof of the house, where an arched opening represents a feature in actual houses through which cool air was conducted into the main bedroom.
