But the builder who had designed this grand structure appears to have been unable to overcome the difficulty of carrying a roof over so vast an expanse.

He was therefore obliged to divide his hall by a wall down the middle; which, though he broke it in an unusual way into portions, and kept it at some distance from both ends of the apartment, still had the actual effect of subdividing his grand room into four apartments of only moderate size.

The halls were paved with sun-burnt brick.

They were ornamented throughout by the elaborate sculptures, now so familiar to us, carried generally in a single, but sometimes in a double line, round the four walls of the apartment.

The sculptured slabs rested on the ground, and clothed the walls to the height of 10 or 12 feet.
