In 1992, the University of Texas Press published Before Writing, Volume I: From Counting to Cuneiform and Before Writing, Volume II: A Catalog of Near Eastern Tokens. In these two volumes, Denise Schmandt-Besserat set forth her groundbreaking theory that the cuneiform script invented in the Near East in the late fourth millennium B.C. - the world's oldest known system of writing - derived from anarchaic counting device. How Writing Came About draws material from both volumes to present Schmandt-Besserat's theory for a wide public and classroom audience. Based on the analysis and interpretation of a selection of 8,000 tokens or counters from 116 sites in Iran, Iraq, the Levant, and Turkey, it documents the immediate precursor of the cuneiform script.
