Groundbreaking study on the processing and consumption of dietary lipids in 6th to 1st millennia BCE Central Germany
Pottery types and decoration have been used extensively by archaeologists to differentiate and describe cultures. The (past) contents and the actual function of the vessels has been less the focus of research. Now, in a groundbreaking study, an international team of scientists from the State Office for Heritage Management and Archaeology (LDA) Saxony-Anhalt and the Autonomous University of Barcelona has explored the culinary traditions in central Germany between the Early Neolithic and the Late Bronze Age (6th – 1st millennium BCE). 124 pottery vessels were analyzed for ancient dietary lipid residues and thus the functional specialization of several pottery types determined.
The first agricultural and pottery-producing societies settled in Central Europe around 7,500 years ago with the dispersion of the Early Neolithic Linear Pottery Culture. Over the following millennia, an exceptional cultural diversity unfolded, which resulted in a wide range of pottery styles and decorations. Pottery types and decoration have been used extensively by archaeologists to differentiate cultures, but the contents and actual uses of the vessels have been explored to a much lesser degree.
Within Central Europe, Central Germany is one of the regions with the most pronounced cultural diversity. This is due to the rich agricultural soils of the loess zone and other natural resources like salt, which attracted people early on. In a groundbreaking study, scientists from the Autonomous University of Barcelona and the State Office for Heritage Management and Archaeology (LDA) Saxony-Anhalt now have analyzed the pottery-based food storing and culinary practices of Central Germany throughout the Neolithic and the Bronze Age (6th – 1st millennia BCE). Lipid residues trapped in a set of 124 period-characteristic pottery vessels of different shapes, sizes, and contexts held in the LDA´s storages were analyzed. This is the largest data series for the region so far, with samples coming from graves and settlements. Lipid analyses can distinguish between residual fats derived from milk, ruminant and non-ruminant animals, as well as of marine or plant origin.
The obtained results confirmed a marked increase in the consumption of dairy products linked to innovations in pottery types (e.g., small cups) during the Middle Neolithic period (Baalberge Culture, 4th millennium BCE). The sets of handled cups and small amphorae of this period nearly always contained dairy lipids, indicating a highly specialized use related to milk-derived food sources. One hypothesis is that the cups served to scoop milk products from larger vessels frequently found in the settlements.
Corded Ware Culture decorated beakers of the 3rd millennium BCE found in funerary contexts instead showed a variety of animal and even plant derived fats suggesting an increase in the importance of non-ruminant products. So far, results do not support the interpretation of these cups as special vessels used for drinking beer, as has been claimed in the past. Also, the arrival of the Corded Ware Culture from the eastern steppe regions seems not to coincide with an increase in the use of ruminant-derived meats or fats, as has been hypothesized. Pigs played a very important role in subsistence habits of these populations. Amphorae (double-handled vessels) of the Corded Ware Culture frequently contain pig-derived fats. The intensive use of dairy products may also have continued into the 3rd millennium BCE, especially amongst Bell Beaker populations. The use of the carinated beakers, particularly from burials near the circular enclosure of Pömmelte, seems to have been highly specialized in dairy products, potentially as a serving vessel. This may reflect specific funerary practices at the site, where the typical grave good, a single drinking vessel, consistently presented a signal of dairy products across multiple burials.
The Early Bronze Age Únětice Culture (ca. 2200–1550 BCE) saw the emergence of a highly hierarchical society. This is the time of the richly furnished monumental princely burial mounds of Leubingen and Helmsdorf as well as the Bornhöck, which has been intensively studied in recent years. The Nebra Sky Disc, which encoded astronomical knowledge that could be used to create calendars, marks the elites of the Únĕtice Culture as powerful masters of time. Their power was secured by armies, whose weapons can be found in the large axe hoards from the Early Bronze Age.
The pottery of the Únětice Culture is highly standardized. Characteristic are undecorated cups with a carinated spindle-shaped body as well as coarse domestic pots with rough plastic decoration. A greater variety of animal and plant derived products was detected in this much more standardized but, surprisingly, more multifunctional pottery with signals for several different lipids.
Overall, the study of the lipid residues in different vessel types from the Early Neolithic to the Bronze Age in Central Germany reveals new data on the broad changes in pottery use and food preparation over time and the complex relationships that prehistoric populations established between food resources and the main means to prepare, store, and consume them. Despite of very constant animal husbandry practices revealed by faunal studies, the consumption of animal derived products changed substantially between the Early Neolithic and the Bronze Age. Hence, animal bones alone are not always a good indicator of subsistence.
