Many inlaid compositions have been found in the temples and palaces of Mari and a number of other Mesopotamian cities, the most famous being the Royal Cemetery at Ur. Fabricated of ivory, shell, limestone, lapis lazuli and slate, inlays were set into bitumen and arranged into a mosaic of geometric patterns and figural friezes. Likely once decorating walls, floors and musical instruments, the scenes often depict mythological creatures, religious rituals, military exploits, and peace-time prosperity.
