Answer the following question in 3-4 complete sentences. How were Sumerian cylinder seals made? What was the purpose for the seals?

Sumerian Cuneiform Cylinder Seal, Iraq, 3000 BCE

Seals were most often made of stone but also sometimes of bone, ivory, faience, glass, metal, wood, or even sun-dried or baked clay. A recessed inscription was carved onto the cylinder, which produced a raised impression when rolled on a clay tablet or envelope.

Answer # 2 The original purpose was to authenticate a document, a wrapper for one such as a modern envelope, or the cover of a container or package holding valuables or other objects. The seal-making device is also referred to as the seal matrix or die; the imprint it creates as the seal impression (or, more rarely, the sealing).
