Different types of materials found in association with a human skeleton found in an 18th century shipwreck in Patagonia (Argentina) were analyzed by means of OM, SEM-EDX, HPLC, and chemical analysis. Alizarin and purpurin, the main anthraquinones of the dye plant Rubia tinctorum L. (madder) were identified as the coloring matter of a red fabric attached to the skeleton. Metallographic and chemical analysis of one of the dome-shaped buttons associated to the human bones revealed that it was composed of a Pb-Sn-Cu alloy known as pewter. The results obtained support the hypothesis that the remains originally were part of a private marine uniform.
