Indeed, due to the complex nature of archeological samples, their chemical and physical analysis inevitably requires a multi-analytical and multi-technical approach. In recent years, studies in archeological sciences and analytical chemistry have been moving towards the same direction. In this context, a step-by-step integrated approach resulted fundamental to maximize the information content and to provide new data on textile manufacturing and trade in antiquity.

Then, these data were enriched by HPLC-HRMS analyses, which confirmed SERS-based hypotheses and also allowed to hypothesize the species of the origin mollusk. For this reason, the characterization of the purple color was the main scope of this research, and to deepen the knowledge of such artifacts, the SERS (Surface Enhanced Raman Scattering) in solution approach was applied. Since the purple was one of the most exclusive dyes in antiquity, its presence in an important commercial site like Pompeii induces us to deepen the knowledge of such artifacts and provide further information on their history. However, one outstanding textile sample displays a brilliant purple color and traces of gold strips.

A great number of textiles have been preserved, rarely maintaining traces of their original color, since they are mainly in the mineralized and carbonized state. The cataclysm left behind an abundance of archeological evidence representing a fundamental source of the knowledge we have about ancient Roman material culture and technology. Vesuvius eruption that destroyed Pompeii in AD 79 represents one of the most important events in history.
