In Closer Look: Cuneiform Writing in Sumer, we can see the way writing progresses from a pictographic form into a syllabic form. The initial impulse in language is to represent ideas and objects through resemblance, which can be seen in the symbols for donkey. In earlier pictographic writing the symbol for donkey resembled the animal form. In the later Sumerian writing, like the clay tablet in Closer Look: Cuneiform Writing in Sumer, the symbol developed into an abstract form. This underscores the increasing importance of writing in civilization. To keep track of the production and distribution of goods, the costs of equipping the military, and records relating to enforcing laws and regulations, writing—perhaps the greatest innovation of the Bronze Age—developed.
