Distribution patterns of cultivated plants in the Eastern Alps (Central Europe) during Iron Age

Carbonized fruits and seeds from two recently investigated Iron Age hilltop settlements, one located north and the other south of the main Alpine range, were analyzed and reveal a detailed insight in the subsistence strategies of the Eastern Alps. The results were compared with archaeobotanical data sets from other Iron Age excavation sites in Austria, Eastern Switzerland and Northern Italy. On the basis of variable data from 17 sites it is not possible to detect a geographical pattern through statistical analyses. On the basis of the frequencies, however, it becomes clear that the principal cereals were Hordeum vulgare (hulled six-rowed barley), Triticum dicoccon and T. spelta (emmer and spelt) and Panicum miliaceum (broomcorn millet). In addition, foxtail millet (Setaria italica) as well as naked wheat played some role. Legumes such as Vicia faba (horse bean) and Pisum sativum (pea) also occurred regularly and supplemented the diet of the prehistoric settlers. More systematic research with standardized methods is however urgently needed to corroborate the existing data.
