About OVIS

What is OVIS?

OVIS (Origins of Variability in Island Systems) is a Marie Skłodowska-Curie Actions fellowship investigating the diet, mobility, and management of ovicaprids — sheep and goats — across the Western Mediterranean islands during the Bronze and Iron Ages.

Why does it matter?

Island communities in the ancient Mediterranean developed distinct strategies for managing livestock, shaped by geography, trade routes, and cultural exchange. By applying stable isotope analysis to faunal remains, OVIS reconstructs these strategies with unprecedented resolution.

Methodology

The project combines zooarchaeological analysis with multi-isotope approaches (carbon, nitrogen, oxygen, strontium) on dental and bone remains. Sites in Menorca, Sardinia, and Sicily are compared to build a regional picture of pastoral practices.

Livestock diet & mobility results

Have you seen the results from the latest isotopic analyses? The difference in δ13C values between Menorca and Sardinia is remarkable — it suggests very different pasture management strategies.

Yes, especially the difference between islands! I wonder if it correlates with the presence of Nuragic trade networks. Are you planning to compare with Sicilian samples?

Does anyone know when the next fieldwork campaign in Sardinia will be? I'm interested in joining the sampling team if there's availability.
