Minero-petrographic and geochemical characterization of "Greco Scritto" marble from Cap de garde, near Hippo Regius (Annaba, Algeria)
Résumé
This work presents the results of the first mineralogical, petrographical and geochemical characterization of the marble quarried from the Cap de Garde headland, not far from Annaba (Algeria). This site is traditionally held by archaeologists to be the main source of supply of the so-called ‘ greco scritto ' marble, which was much used by the Romans for architectural and decorative–ornamental purposes, locally from the first century BC , and in Rome and central and southern Italy from the late Flavian period until the fourth century AD . The databank relating to the quarried material, created here for the first time, is used to establish the origin of ‘ greco scritto ' found in six important Roman cities of North Africa: Hippo Regius and Cuicul (Djemila), in Algeria; Volubilis , in Morocco; Cyrene, in Libya; and Carthage and Utica in Tunisia. The results of this archaeometric study support the hypothesis (already put forward by authors) that the ‘greco scritto' used in the Roman Mediterranean originated from different sites, and suggest the existence of a number of North African quarries, also in the vicinity of Annaba.
