The central issues discussed in this new collected work in the highly successful ancient textiles series are the relationships between fiber resources and availability on the one hand and the ways those resources were exploited to produce textiles on the other. Technological and economic practices - for example, the strategies by which raw materials were acquired and prepared - in the production of textiles play a major role in the papers collected here.0Contributions investigate the beginnings of wool use in western Asia and southeastern Europe. The importance of wool in considerations of early textiles is due to at least two factors. First, both wild as well as some domesticated sheep are characterized by a hairy rather than a woolly coat. This raises the question of when and where woolly sheep emerged, a question that has not up to now been resolvable by genetic or other biological analyses. Second, wool as a fiber has played a major role both economically and socially in both western Asian and European societies from as early as the 3rd millennium BCE in Mesopotamia, and it continues to do so, in different ways, up to the modern day. Despite the importance of wool as a fiber resource contributors demonstrate clearly that its development and use can only be properly addressed in the context of a consideration of other fibers, both plant and animal. Only within a framework that takes into account historically and regionally variable strategies of procurement, processing, and the products of different types of fibers is it possible to gain real insights into the changing roles played by fibers and textiles in the lives of people in different places and times in the past.
