Cuneiform law
Unlike modern codes, Cuneiform law provides no universal formula for general areas of law. Rather, laws typically consist of specific "if... then..." cases that are meant to act as an example or precedent. Punishments for crimes vary from code to code, but not all prescribe vengeance. Some call only for fines in certain instances, such as in the Code of Ur-Nammu, where one line reads: "If a man knocks out the eye of another man, he shall weigh out one-half a mina of silver." These cases are sometimes arranged in a seemingly random order, though this may be the result of an inability to properly interpret them today as they would have been at the time they were in force.
History of communication
The original Sumerian writing system was derived from a system of clay tokens used to represent commodities. By the end of the 4th millennium BC, this had evolved into a method of keeping accounts, using a round-shaped stylus impressed into soft clay at different angles for recording numbers. This was gradually augmented with pictographic writing using a sharp stylus to indicate what was being counted. Round-stylus and sharp-stylus writing was gradually replaced about 2700–2000 BC by writing using a wedge-shaped stylus (hence the term cuneiform), at first only for logograms, but developed to include phonetic elements by the 2800 BC. About 2600 BC cuneiform began to represent syllables of spoken Sumerian language.
