Crop Fertility Conditions in North-Eastern Gaul During the La Tène and Roman Periods: A Combined Stable Isotope Analysis of Archaeobotanical and Archaeozoological Remains

ABSTRACT

Considerable archaeobotanical datasets describe cereal cultivation in north-eastern France, from the Iron Age to the Roman period. This study aims to complement these by using stable isotope analysis on charred cereal grains. Soil fertility was investigated through δ¹⁵N and δ¹³C analyses of 1480 charred cereal grains, dated from the Late La Tène to the Late Antiquity periods. In the Île-de-France, charred grain Δ¹³C values suggested good hydric conditions, with drier episodes in the 1st and 3rd century AD; while in Champagne, the lower Δ¹³C values for spelt reflect the lower water holding capacity of the chalky soils. A wide range of cereal δ¹⁵N values (0.8–8.7‰) implies a wide range of soil fertility conditions. Jouars-Pontchartrain and Palaiseau (Île-de-France) yielded the highest cereal δ¹⁵N values, whereas Acy-Romance (Champagne) delivered among the lowest. From these three sites, the δ¹⁵N values of red deer bone collagen were used to estimate the reference δ¹⁵N values for unmanured plants. Unlike in Acy-Romance, there were significant differences in Palaiseau and Jouars-Pontchartrain, indicating that the cultivated cereals inherited their high δ¹⁵N values from manured soil. At Jouars-Pontchartrain, the δ¹⁵N value (almost 9‰) suggested a high trophic level manuring source, possibly from pig and/or human faeces.     

Evidence for “Celtic migrations”? Strontium isotope analysis at the early La Tène (LT B) cemeteries of Nebringen (Germany) and Monte Bibele (Italy)

Strontium isotope analysis on human remains from the Iron Age (4th/3rd century BC) cemeteries of Nebringen, Germany and Monte Bibele, Italy were carried out to investigate the role of residential changes during the period of the historic “Celtic migrations”. From an archaeological perspective, the location of the cemeteries in the Celtic core (Nebringen) and expansion area (Monte Bibele), and the distinctive development of their material culture, suggest that the buried populations had differing mobility rates. On the contrary, the strontium results indicate that only few individuals were mobile or non-local. There is, however, a difference in variation of strontium isotope ratios between the two studied cemeteries, presumably caused by differing geological conditions. In Nebringen changing use of cultivated land in a geologically heterogeneous environment most likely caused varying strontium isotope ratios even within the same jaw, while individual mobility over longer distances can also not be excluded. In Monte Bibele the range of strontium isotope ratios is narrow, and this may be explained by a community living in the same village and using the same agricultural resources. For various prehistoric time periods it has been suggested that some population groups were more mobile than others, for example because they had special social roles. In the two cemeteries studied here, males have slightly more often a non-local birthplace or moved during childhood. In contrast, females had isotope signatures which are more consistent with the local geological environment. Male mobility is, however, not correlated with burial as a warrior, and patrilocal residential patterns were not observed among females. Foreign and local items are found with isotopically local and non-local individuals and objects per se do not indicate descent. The motives for residential changes were, therefore, varied and not constrained to a specific area or population group. The presented dataset provides details on the way of life and land-use in the Celtic communities, for which information is otherwise absent.
