Geochemical and isotopic provenance determination of gypsum used for stucco artworks: application to Florentine stucco reliefs
Gypsiferous rocks of Tuscany and derived materials (i.e. alabaster, stucco and gesso) have been frequently used as sculptural materials. Remarkable examples are attested from the Renaissance Florence. At the junction of two ongoing programs, dealing respectively with the study of 15th century stucco...

À la jonction de deux études scientifiques en cours, portant respectivement sur les reliefs en stuc du xve siècle (dits Madonne di gesso) et sur la provenance des albâtres employés dans des œuvres d’art, nous avons entamé une recherche sur les sources d’approvisionnement en gypse brut en réalisant une prospection géologique dans les alentours de Florence. Une démarche multi-analytique a été adoptée pour identifier des marqueurs de provenance géochimique sur trente échantillons de roche géoréférencés ; les éléments-traces liés à la fois au gypse et aux minéraux synsédimentaires, ainsi que les isotopes du gypse (S, O, Sr) ont pu être testés. Les résultats présentés ici apportent un éclairage sur l’origine géographique des matériaux bruts utilisés pour les reliefs en stuc dans les ateliers florentins. |

Gypsiferous rocks of Tuscany and derived materials (i.e. alabaster, stucco and gesso) have been frequently used as sculptural materials. Remarkable examples are attested from the Renaissance Florence. At the junction of two ongoing programs, dealing respectively with the study of 15th century stucco reliefs (called Madonne di gesso) and the provenance of European alabasters used in artworks, an investigation on raw gypsum supply was conducted via a geological survey in the surroundings of Florence. Looking for geochemical provenance markers, a multi-analytical approach was carried out on 30 geo-referenced rock samples. In particular, trace elements, related both to gypsum and synsedimentary minerals, and gypsum multi isotopic fingerprints (S, O, Sr) were tested. The results obtained are discussed, disclosing insights in the geo-sourcing of raw materials used for stucco reliefs in Florentine workshops. |
