The Standard of Ur survived in only a fragmentary condition, as the effects of time over the last several millennia had decayed the wooden frame and bitumen glue which had cemented the mosaic in place. The weight of the soil had crushed the object, fragmenting it and breaking the end panels. The present form of the artifact is a reconstruction, presenting a best guess of its original appearance. It has been reconstructed as a hollow wooden box measuring 21. 59 centimetres (8. 50 in) wide by 49. 53 centimetres (19. 50 in) long, inlaid with a mosaic of shell, red limestone and lapis lazuli. The box has an irregular shape with end pieces in the shape of truncated triangles, making it wider at the bottom than at the top. Inlaid mosaic panels cover each long side of the Standard. Each presents a series of scenes displayed in three registers, upper, middle and bottom. The two mosaics have been dubbed 'War' and 'Peace' for their subject matter, respectively a representation of a military camp
