The ornamental stones of the Roman thermal baths of Teate Marrucinorum (Chieti, Italy): autoptic, geochemical and minero-petrographic multi-analytical characterisations🏛️
This study, published in Archaeological and Anthropological Sciences, investigates the decorative stones used in the Roman thermal baths of Teate Marrucinorum (Chieti, Italy) through an integrated analytical approach. Provenance studies on polychromatic varieties traditionally relied only on visual comparison and expert assessment. In this study, ornamental stones from the 2nd-century AD thermal complex were investigated through visual, petrographic, mineralogical and geochemical analyses. Those specimens have been classified into polychrome stones, grey-veined marbles, and white crystalline marbles based on macroscopic characteristics. Mineralogical, petrographic, geochemical, Raman, and isotopic analyses revealed that the grey-veined marble is Greco Scritto quarried near Ephesus (Turkey), and the provenances of white marbles are Carrara (Italy) and Marmara Island (Turkey). The coloured stones resulted Pavonazzetto from Afyon Region (Turkey), Cipollino Verde from Eubea (Greece), Portasanta (Chios Island), and Breccia di Settebasi (Skyros Island). Combining visual observations with quantitative analyses enabled a more reliable reconstruction of the provenance and properties of the stones used in the Roman baths. Additionally, the provenance and quality of the identified Roman stones highlight the significance of Teate Marrucinorum during the Imperial period.
