Studies on archaeological olive fruitstones from the Archaic and Punic periods (7th–3rd century bc) of Sardinia, Italy

Abstract

Recent archaeological investigations in the lagunas di Santa Giusta and Mistras, waterlogged sites in central-west Sardinia, Italy, have enabled the recovery of archaeobotanical remains, exceptional in terms of quantity and preservation, dated to the Archaic and Punic periods in the 7th–3rd century bc . Among the finds was a significant amount of Olea europaea fruitstones (endocarps), which are discussed here. The morphometric features of these fruitstones, extrapolated by image analysis, were analysed statistically and compared to modern wild olive populations and cultivars. Thanks to the image analysis, it was possible to recognize the presence of O. europaea var. sylvestris (wild olive) and O. europaea var. europaea (cultivated olive) from the Archaic and Punic periods and to make suggestions about their use. Moreover, most of the cultivated type fruitstones identified by the statistical analysis can be attributed to a group of modern Sardinian cultivars, providing new data on the origin of cultivation and use of olives in Sardinia.
