Prehistory of plant growing and collecting in northern Italy, based on seed remains from the early Neolithic to the Chalcolithic (c. 5600–2100 cal b.c.)

Abstract

The stages of the early Neolithic and the spread of agriculture in northern Italy are difficult to determine and basically still unclear, since this region was influenced by deeply different cultures coming from both the Mediterranean coasts and the Balkans. The complex interrelations due to the contributions from both cultures are reinterpreted here thanks to recent data, modifying a picture which 15 years ago was believed to be definite. According to radiocarbon chronology, the appearance of the earliest farming communities in northern Italy should be dated around 5600–5500 cal b.c. Early farmers cultivated several cereal and pulse taxa, of which the more important were Hordeum vulgare/distichum, Triticum dicoccum, T. monococcum, T. aestivum/durum/turgidum, Lens culinaris and Pisum sp. In addition they gathered many wild plants. The spread of agriculture was a rapid phenomenon and within a few centuries agriculture was established into the Alps. Little is known about the middle and late Neolithic, with the Square-mouthed pottery culture “Bocca Quadrata”, from c. 5100 cal b.c. onwards, since most of the archaeological features discovered up to the present have produced only a few plant remains. We demonstrate the introduction of poppy and a few other innovations like a slightly increased cultivation of free-threshing cereals and flax. Archaeobotanical analyses from Chalcolithic or Copper Age settlements, from c. 3500 cal b.c. onwards, are even scarcer and a comparison with the earlier Neolithic settlements does not yet seem possible.
