Underwater investigation on a marble cargo wreck at Capo Bianco (Isola di Capo Rizzuto, Crotone)

The cargo of marble blocks off Capo Bianco was dated to the Roman period. New sampling and analysis has identified Carrara marble, and also Rosso di Francia and Portargento, which strongly suggests a post-medieval date. This leads to the suggestion that nearby finds dating between the second half of the 18th century and the first half of the 19th may come from the same ship, perhaps sailing from France and Liguria to deliver stone in southern Italy. This is rare evidence of the post-medieval marble trade and demonstrates the importance of archaeometric analysis for the interpretation of wrecked cargos.
