Armenian cochineal ( P orphyrophora hamelii) and purpurin‐rich madder in ancient polychromy

Abstract

Samples removed from funeral figurines, dated the third to the second centuryBC(Hellenistic period) and found in Macedonia, Greece, are investigated using high‐performance liquid chromatography. Two results are reported that provide new insights into ancient polychromy. Firstly, high‐performance liquid chromatography results, in combination with historical information, indicate that insect species of cochineal, most probablyPorphyrophora hameliiBrandt, was used in Hellenistic objects. Secondly, madder detected in the archaeological samples contains high amounts of purpurin (alizarin is either not detected or detected in trace). This relative composition, which is recorded using the hydrochloric acid method for dyestuff extraction, is consistent with that prepared from wild madder (Rubia peregrinaL.), which is a common plant in the Mediterranean region.
