Standard of Ur

This standard is made from a tar-like substance called bitumen with an inlay of shell, lapis lazuli, and red limestone. Each register comes together to form a visual narrative. The upper panel, depicted here, is called "War." It depicts four-wheeled chariots, infantry soldeiers, prisoners, and a large figure in the center presumed to be a king. The lower panel called "Peace" depicts people preparing for a feast and playing music. The Sumerians utilized hierarchy of scale on their art, which indicates a figure's importance by how large they are portrayed compared to everyone else in the image.
