Before Tony caps a wall with a protective layer, it is carefully planned and recorded. In addition, Joel does a 3-D laser scan of the whole palace and we photograph the brickwork. The last step is to make carefully detailed brick-by brick drawings of the tops of each wall along with elevations and sections of special features. Although many of the earlier expeditions made plans of the palace, they did not record this degree of detail. In examining the walls this closely, many details are revealed. I just finished drawing a long room called M1 which appears to have been one of a series of storage rooms or magazines surrounding the central core of the palace.
M1 is a long, narrow corridor with low buttresses jutting out perpendicular to the walls. The buttresses, constructed of a different size brick, were added after the walls had received a finishing coat of plaster. They were placed at regular intervals of 1.85 meters and would have supported a low shelf for storing food and supplies for the palace residents.
In fact, the original Metropolitan Museum Expedition discovered a wall painting of a bowl of fruit, maybe pomegranates or dom-palm nuts, in a basket on a stand on one of the buttress walls.
This same device of painting what would be stored on the shelf above can be seen in some of the tombs in the Valley of the Kings. The Egyptians obviously believed very strongly in a place for everything and everything in its place — for all eternity!
