This article investigates the production of textiles in Thrace during the first millennium BC. It presents a functional analysis of textile-production tools from three towns in Thrace: Koprivlen, Adzhiiska Vodenitsa near Vetren, and Seuthopolis, and from Kastanas in Macedonia. The analysis shows that over the course of the Iron Age, textile production became more diversified and intensive. This process unfolded parallel to the emergence of opulent elite burials and urban communities. By examining a wider range of archaeological, iconographic, and textual data, the article contributes to our understanding of how the demand for textiles, and their consumption in different socially meaningful ways, connects to changes in production.
