Descrição:

Cuneiform, or Sumero-Akkadian cuneiform,[a] was one of the earliest systems of writing, invented by Sumerians in ancient Mesopotamia.[b][4][5] It is distinguished by its wedge-shaped marks on clay tablets, made by means of a blunt reed for a stylus.[6][7][8][9] The term cuneiform comes from "cunea", Latin for "wedge".[
