Roman landscape and agriculture on the Ligurian coast through macro and microremains from aVada Sabatiawell (Vado Ligure, Italy)

The results of an analysis on plant remains (fruit, seeds, pollen and wood) found in sediments in a Roman well in Vada Sabatia (Vado Ligure, Liguria, Italy), dated between the first and fourth centuries AD are presented. The remains are well preserved and constitute an exceptional record of the Ligurian area. Five layers have been recognised: three corresponding to the well when in use and two to the well when it was no longer in use. The vegetational cover of the area has been found to be similar to that observed in the coastal plain near Albingaunum (Albenga) pertaining to the same period. Moreover, the two superficial layers have cumulated a large amount of macroremains related to the period in which the well was no longer in use. The principal tree and vegetable crops and cereals of the coastal plain were present, due to the influence of maritime and mercantile trade, as were the prevailing ruderal and weed species and the tree cover. The presence of carpological remains of Castanea sativa, Secale cereale, Beta vulgaris and Cucumis sativus is reported for the first time in the Roman Age in Liguria. The influence of the arrival of the Romans can be seen from new crops, such as Prunus persica, and the introduction of exotic fruit like Phoenix dactylifera and Ziziphus jujuba. Several wooden artefacts, for example, a rack for drying lucerne and a tool handle, made of Cornus or Viburnum and Viburnum cf. lantana respectively, have been found. The well has proved to be an ideal location for the preservation of plant remains compared with other studied archaeological situations in Liguria and in Southern France, as it presents a higher variety of cultivated fruits, vegetables and cereals. © Association for Environmental Archaeology
