The article delves into the comprehensive study of the Los Amores Mosaic at the Baelo Claudia archaeological site, focusing on the archaeometric analysis of tesserae to identify raw materials, colourants, and opacifiers. By utilising portable MRS and hXRF techniques for in situ analysis, the research uncovered the presence of Cu-based chromophore agents in the tesserae, shedding light on the materials used in the mosaic’s creation. The study not only contributes to the understanding of ancient technology and trade of raw materials but also reveals the existence of a mosaic workshop in Upper Guadalquivir, providing insights into ancient craftsmanship practices.
Funded by Project Cástulo and the University of Jaén, the research emphasises the significance of interdisciplinary approaches in archaeology and highlights the efficacy of portable analytical methods in overcoming sampling limitations. The findings offer valuable information for evaluating the conservation and restoration needs of the mosaic, emphasising the importance of conducting thorough archaeometric studies in the field of art history research. By analysing tesserae composition and coloration, the study enhances our knowledge of Roman mosaic craftsmanship, providing a deeper understanding of the historical and cultural context in which the Los Amores Mosaic was created.
