Cap de Barbaria II: the village

CBII is an open-air village (Figure 1) of nine structures, three of which are naviforms (Figure 2). These are boat-shaped house structures built using a cyclopean masonry technique (e.g. Salvà & Hernández-Gasch Reference Salvà, Hernández-Gasch and Belarte2009), typical of domestic structures in the wider Balearic Bronze Age. Two different phases of construction have been identified at the site, and new radiocarbon dating attributes these to 1580–1531 cal BC (phase 1) and 997–927 cal BC (phase 2) (Sureda et al. Reference Sureda, Camarós, Cueto, Teira, Aceituno, Albero, Álvarez-Fernández, Bofill, López-Dóriga, Marín, Masclans, Picornell, Revelles and Burjachs2017a). Abandonment of the village was probably related to the Phoenician colonisation of the island after the ninth century cal BC.

CBII was first excavated between 1979 and 1987 by the Archaeological Museum of Ibiza. Since 2012, a multidisciplinary project has conducted six seasons of fieldwork (2012–2017) focused on naviforms 7–9 (Figure 3) and outside areas. Excavation of the naviforms has revealed a number of internal features: paved floors, benches, storage structures and hearths. Material culture is also abundant, including metal and flint artefacts, grinding stones, pottery, marine shells, animal bones, charcoal and seed remains, representative of both domestic and production activities (Figure 4). These materials have been subject to a variety of analyses: lithic studies, archaeometallurgical analysis, zooarchaeological and archaeobotanical approaches (including palynological, anthracological, starch grain and macrobotanical remains analysis), and petrological studies of the pottery (Sureda et al. Reference Sureda, Camarós, Cueto, Teira, Álvarez-Fernández and López-Dóriga2017b).

Cave 127: the funerary context

Cave 127 (Figure 5) is a natural cave used for prehistoric burial. Since its discovery in 2014, archaeological remains relating to two buried individuals and their associated funerary goods have been recovered. These are contemporaneous with the Ca na Costa dolmen (the other known funerary context of the island) and with the oldest phase of CBII. A range of analyses on the material from cave 127 is currently ongoing, including radiocarbon dating, nitrogen and oxygen isotope analyses, palaeopathology and DNA.

Preliminary results and future perspectives

Island archaeology has long theorised about the mechanisms of colonisation, from initial discovery through to definitive settlement. Recent approaches (e.g. Ramis Reference Ramis, Knapp and Van Dommelen2014) emphasise that island colonisations are closely related to social and technological conditions, and also to the local environmental resources available. Our project proposes three key questions: 1) how did the population cope with the scarcity of natural resources (metallic ores, flint, pastures or arable land)?; 2) did they overcome these limitations through the development of new economic strategies and/or by establishing maritime exchange?; and 3) did the settlers remain isolated throughout the Bronze Age?

These questions are essential for understanding how these first settlers exploited local and/or exogenous resources to establish the first successful communities and how they guaranteed their subsistence. This approach aims to identify the presence or absence of insular particularities, and to assess the degree to which island populations were integrated into regional or long-distance exchange networks.

Our results suggest that the strategies developed in Formentera required specific adaptation of behaviours in comparison to other Balearic cases (Sureda et al. Reference Sureda, Camarós, Cueto, Teira, Álvarez-Fernández and López-Dóriga2017b). Such adaptation required modification of the island's environment through the introduction of new species for optimal subsistence (e.g. caprines, millets) and intensive exploitation and diversification concerning the use of local resources (e.g. marine resources, limestone). Exogenous materials (e.g. copper-based metals, flint) have also been identified and are important for the evaluation of isolation vs interaction. In sum, the results of our work on Formentera challenge ideas about the first human settlement of the Balearics, especially according to its specific subsistence strategies; future research will contribute to a better understanding of the wider Mediterranean Bronze Age.
