It is about fifty feet on a side. The center of the space is occupied by three large artifacts, or rather three-dimensional renderings of artifacts. In the center is a thick slab of baked clay, hanging in space, about the size of a coffee table, and about a foot thick. Hiro suspects that it is a magnified rendering of a smaller object. The broad surfaces of the slab are entirely covered with angular writing that Hiro recognizes as cuneiform. Around the edges are rounded, parallel depressions that appear to have been made by fingers as they shaped the slab.
