Study of seventeen wool-on-cotton patterned textiles from the temple site of Pachacamac, Peru, collected by Max Uhle and held by the University Museum, University of Pennsylvania. The author examines whether each piece is brocade (woven supplementary yarns) or embroidery (sewn), finding two clear brocades, three clear embroideries, and the rest a mixture or indeterminate. It describes the design types (reversed diagonal bands, diapered repeats, simple repeats, rectangular block figures), colors, yarn spin and diameters, and construction details. A table of yarn data and many photographs and motif drawings are included, and the author argues for finding looms with unfinished cloth to resolve the classification.
