Cuneiform law
Cuneiform law refers to any of the legal codes written in cuneiform script, that were developed and used throughout the ancient Middle East among the Sumerians, Babylonians, Assyrians, Elamites, Hurrians, Kassites, and Hittites. The Code of Hammurabi is the most well-known of the cuneiform laws, but there were a number of precursor laws.
Cuneiform
From about 2900 BC, many pictographs began to lose their original function, and a given sign could have various meanings depending on context. The sign inventory was reduced from some 1,500 signs to some 600 signs, and writing became increasingly phonological. Determinative signs were re-introduced to avoid ambiguity. Cuneiform writing proper thus arises from the more primitive system of pictographs at about that time (Early Bronze Age II).
