Dairying in antiquity. II. Evidence from absorbed lipid residues dating to the British Bronze Age

Molecular and isotopic analyses were undertaken of absorbed lipid residues from 256 pottery vessels obtained from four southern British Bronze Age sites (Potterne, Brean Down, Black Patch and Trethellan Farm). The results confirm that not only were Ancient Britons utilising dairy products during this period, but also that they were processed in pottery vessels on a large scale. This has been demonstrated through the determination of the compound-specific stable isotope values of the principal fatty acids found in animal fats (C16:0 and C18:0) that allows ruminant dairy and ruminant/non-ruminant adipose fats to be distinguished. The proportion of sherds yielding degraded dairy fats at each of the sites is variable, with the highest occurrence being from Potterne, and the lowest occurrence being from Black Patch. The faunal remains, and vessel characteristics (e.g. rim diameter and vessel type) are compared with the organic residue analyses, and intra-site variability is investigated at Trethellan Farm.
