Food storage in two Late Bronze Age caves of Southern France: palaeoethnobotanical and social implications

Abstract

This paper presents new archaeobotanical results from two previously studied Late Bronze Age caves situated in Southern France, Balme Gontran and Baume Layrou. At each site a thick black layer, characterised by a very high density of charred seeds, is shown to be composed of the remains of burnt crop stores. In Baume Layrou a small proportion of desiccated plant remains was preserved in addition to the bulk of carbonised material. In Balme Gontran, Triticum spelta and Panicum miliaceum predominated and were independently stored. Lens culinaris, Vicia faba and Setaria italica were secondary species of some importance and could have been stored as well. Storage at Baume Layrou was above all composed of hulled Hordeum vulgare, Triticum spelta and P. miliaceum. Other possibly stored species were Triticum aestivum/durum/turgidum, T. dicoccon and V. faba. It seems that most of the crops were grown in pure stands, with the exception of S. italica and Triticum monococcum which may have been mixed in small proportions with common millet and emmer respectively. Crops were stored in ceramic vessels, probably also in bags and wooden containers like baskets. Millet grains were stored in their husks while glume wheats were dehusked. Dehusking before storage does not seem to have been the common practice at the time. It seems moreover rather unsuitable for grain storage in caves. In Baume Layrou a small proportion of cereal kernels had started to germinate, presumably due to the humidity of the cave. We are making the assumption that the caves were not used for usual long term storage but to store food supplies for a small group of people who intended to live here for a short period, perhaps taking refuge during disturbed times. Crops could have been dehusked to reduce the weight and volume of the load to transport to the caves on steep and difficult paths.
