Abstract

Selected yellow and brown colored textiles from the Hopewellian Seip Mound group were examined visually and photographed. In some cases, the yarns are colorant saturated and the colored patterns are nearly identical on both sides of the textiles. In addition to the use of several colors, fringe and possibly leather are used as decorations. Particulate material shed from these fabrics, or small samples strategically removed based on the results of the forensic photography, were examined with optical microscopy, revealing that the fabrics are made of dyed rabbit hair and bast fibers. Energy dispersive spectroscopy (EDS) of a subset of the samples indicates that there is no significant difference in elemental composition between the different colors. However, the high carbon and copper content are signs of mineralization of the fibers. These textiles reflect multifaceted textile construction methods with elaborate decoration techniques as well as the use of complex dye technology.

Abstract

Protocols for photography of archaeological textiles to detect components of differing chemistry that are indicative of colourants were developed. Parameters of light source, camera distance, filter type, film type, film speed, and aperture size were evaluated for visible, UV-reflectance, UV-fluorescence, and infrared photography. Using these techniques facilitates selective sampling for further analysis that maximizes critical data acquisition while minimizing destruction of the artefact. Hence, forensic photography of archaeological perishable materials should be regarded as a precursor to destructive analytical methods.
