Temple structures

Temple structures were built on foundations of stone slabs set into sand-filled trenches.[71] Walls and other structures were built with large blocks of varying shapes.[72][Note 6] The blocks were laid in courses, usually without mortar. Each stone was dressed to fit with its neighbors, producing cuboid blocks whose uneven shapes interlocked.[73] The interiors of walls were often built with less care, using rougher, poorer-quality stones.[74] To build structures above ground level, the workers used massive construction ramps. When cutting chambers in living rock, workers excavated from the top down, carving a crawlspace near the ceiling and cutting down to the floor.[75] Once the temple structure was complete, the rough faces of the stones were dressed to create a smooth surface. In decorating these surfaces, reliefs were carved into the stone or, if the stone was too poor-quality to carve, a layer of plaster that covered the stone surface.[76] Reliefs were then decorated with gilding, inlay, or paint.[77] The paints were usually mixtures of mineral pigments with some kind of adhesive, possibly natural gum.[76]
