Charcoal analysis was carried out in two archaeological sites on the north slope of the Somma-Vesuvius volcano, not far from Naples. Both sites were inhabited between the 2nd century AD and AD 472, when a great Vesuvius eruption (so called Pollena eruption) buried them. In both sites, Castanea sativa wood was largely used for architectural structures as well as firewood. Ten 14C dates, spanning between the 1st and the 5th century AD, testify to a continuative use of this wood throughout the life of the sites. The comparison between archaeobotanical and pollen data from other sites in southern Italy suggests that chestnut woods were close to the sites studied and had a restricted spreading, possibly in a refugium area on Vesuvius' foothills. The match between archaeological charcoals and pollen data suggests that the Romans did not spread chestnut cultivation in the entire Campania region and that chestnut probably became a common timber in Campania starting from the 5th-6th century AD.

Abstract: Cultural landscapes were prominent during the Early Roman period when agronomic knowledge allowed the spread of intensive land exploitation in most of the available land. The aim of this contribution is to explore whether for the Campania region (Southern Italy) archaeoenvironmental data would support continuity or change in the cultural landscape of Roman tradition in the 4th and 5th centuries. To do so, new data from two sites located on the northern slopes of the Vesuvius, both buried by the AD 472 eruption have been investigated. Charcoal analysis, 14C dating, and chemical analysis of organic residues were carried out in order to study the landscape and the food production at these sites. The results suggest the persistence of the Roman cultural landscape until the 4th and 5th centuries in this area. The landscape is in fact strongly marked both in agriculture and woodland exploitation and management, being characterized by managed chestnut forests as well as valuable cultivations of walnut, large vineyards, olive groves, and probably orchards and crops. The integrated approach with archaeobotanical and archaeometric analyses proves to be a powerful method for the study of the past landscapes, providing a good insight into the environment. Furthermore, this study provided the most ancient evidence of chestnut silviculture for wood. [Copyright &y& Elsevier]
