The progress of ZANBA was badly affected by the global pandemic. All planned research activities had to be put on hold for over a year. During that time, the lead researcher, Dr Emily Holt, pursued approved alternative research goals related to the themes of the original proposal, resulting in three scientific publications and a fourth publication under review. It was possible to begin the originally proposed research when pandemic restrictions were lifted, and Dr Holt, Co-PI Dr Richard Madgwick, and team member Dr Davide Schirru were able to complete the first part of the project. The research for the second part of ZANBA is ongoing.
ZANBA is achieving its goals through three related initiatives. First, ZANBA is mapping the strontium isoscape of central Sardinia. Strontium isotope analysis is increasingly used in archaeology to study the mobility patterns of humans and animals. For ZANBA, understanding the changing mobility of domestic animals provides insight into territorial control, cooperation networks, and political consolidation. However, the strontium ratios of ancient animals must be interpreted against a map of the bioavailable strontium in a landscape, and no such map exists for Sardinia. Dr Holt selected 128 sampling locations representing 19 lithological zones across central Sardinia, then Dr Schirru collected multiple plant samples from each of the locations. These samples were freeze dried, crushed, and mixed to produce a homogenized sample that was then processed and analyzed for strontium. The results of these analyses are being used to produce an isoscape map that will enable ZANBA's specific goals and will also have legacy benefits for researchers of any time period who want to study mobility on Sardinia.
The second initiative of ZANBA is to conduct isotope analysis of zooarchaeological remains from Sa Conca ‘e sa Cresia, an early Nuragic site (c. 1750-1450 BCE) located on the Siddi Plateau in central Sardinia. These remains will be analyzed for carbon, nitrogen, and strontium: isotopes that will allow Dr Holt to interpret how and where the animals were raised. ZANBA is the first study to use strontium isotope analysis to understand Nuragic animal remains.
ZANBA’s third initiative is to complete a detailed morphological study of the zooarchaeological remains from Sa Conca ‘e sa Cresia. The assemblage from Sa Conca ‘e sa Cresia includes more than 6000 individual bones and bone fragments from stratigraphic contexts that are securely dated by a sequence of seven radiocarbon dates. When the morphological study is complete, it will be one of the largest and most detailed zooarchaeological studies available for an early Nuragic site.
Dissemination of the results of ZANBA is ongoing. To date, the work has been presented at two international conferences. Publication of the strontium isoscape of central Sardinia is expected in 2023, with the results of the morphological and isotopic analysis of the animal remains from Sa Conca ‘e sa Cresia to follow.
Public dissemination of the results in both English and Italian has also been a priority. Updates on ZANBA’s ongoing progress are available in both English and Italian on Dr Holt's blog Errant. ZANBA’s research has been featured in English-language guest posts on the blogs Peopling the Past, Stable Isotopes in Zooachaeology, and Celebrating 100 Years of Archaeology: Archaeology and Conservation at Cardiff University. ZANBA has also been featured in the Italian-language newspaper Unione Sarda. Dr Holt has presented ZANBA research in public outreach activities with schools in Europe and the United States, as well as in Cardiff University’s European Researchers Night 2020.
