Caption: "Cult scene: the worship of the sun-god, Shamash. Limestone cylinder seal, ancient Mesopotamia."

The cylinder seal is on the left and a modern (?) impression is on the right. Impression figures are inversed from the cylinder seal figures, of course.

The ancient Mesopotamians had a form of proto-printing (from circa 3500 BCE on) using cylinder seals to make identical clay tablet images that were used, among other things, to authenticate documents just like a modern seal or rubber stamp.

Cylinder seals are often works of art as the one in the image illustrates.
