In this thesis, I evaluate different approaches for the study of settlement and land use during the Metal Ages (ca. 3000-800 BC) in northern Calabria (Italy). Our understanding of communities in this period is tainted by biases which result in incomplete and unbalanced reconstructions of land use and settlement dynamics. I distinguish three main types of biases: methodological biases, research or conceptual biases, and biases caused by landscape and site formation processes (chapter 3). This thesis aims at countering these biases by testing and refining methods for landscape-archaeological research on and around small surface pottery scatters in the Raganello basin, mapped by the Groningen Institute of Archaeology (GIA) between 1990-2010; in chapter 2 I present the scientific and environmental backgrounds of my research. The research was conducted as a sub-project of the interdisciplinary Rural Life in Protohistoric Italy research program, funded by the Dutch Organization for Scientific Research (NWO) and directed by dr. P.M. van Leusen. Within this framework, I collaborated closely with the researchers in two other sub-projects, dr. K.L. Armstrong (archaeo-geophysical methodology) and prof. dr. J. Sevink (soils and soil processes); therefore, relevant geophysical and pedological results from their research are used in this thesis.
The heart of this thesis is formed by chapters 4, 5, and 6. Chapter 4 justifies my research strategy for the study of the 155 known Metal Age surface sites in the Raganello basin. The first step in this strategy was the design of a site classification system based on assemblage variation and location properties, avoiding a priori assumptions about the character and function of these sites. Subsequently, selected examples of six site classes were intensively investigated. I explain which field methods were used to study these sites, and why: high resolution archaeological (re-)surveys, geophysical surveys, manual augering, on- and off-site soil studies, test pits, and topsoil stripping. The results are summarized in chapter 5. Magnetic-based geophysical techniques proved to yield the best results in our area; this thesis therefore presents a number of magnetometry and magnetic susceptibility datasets and attempts to associate magnetic features with archaeological and pedological data. In chapter 6 the effectiveness of my field method is assessed with regard to my research aims, and recommendations are made for further refinement of landscape-archaeological research methodology. The methodological results of my study can be summarized in four themes:
- The original research design of the GIA surveys, based on a standard surface coverage of 20%, is too coarse to reliably detect the location, character and density of Metal Age activity areas. I propose a coverage of at least 40%;
- Geophysical data show that surface mapping by field walking alone is insufficient for mapping archaeological landscapes: magnetometry data revealed archaeological features not associated with surface artefact concentrations. Furthermore, seemingly ‘natural’ features such as gullies and local depressions can be of archaeological relevance
- Slope processes may lead to dramatic topographical changes; therefore, systematic study of the stability of landscape zones is crucial to archaeological landscape research;
- Minimally invasive field techniques (coring, test pitting) are essential to assessing the effect of anthropogenic and natural depositional processes on the archaeological record. The interpretation of manual augering profiles in stony soils should be done with caution; sites in stony debris slopes all contain deep archaeological stratigraphies, despite their seemingly shallow depth as inferred from coring attempts.
The central proposition of this PhD research project is that seemingly unpromising small surface scatters can yield many new insights in Metal Age land use and settlement, provided that they are investigated in a systematic, intensive, and interdisciplinary manner. The high-resolution integration of archaeological, geophysical and pedological datasets is essential. This argument is elaborated and illustrated with three case studies in chapter 7: the probable urnfield on Monte San Nicola, site RB073 in the upland valley which turned out to be only the tip of an iceberg of a buried prehistoric landscape, and the Contrada Damale area in the foothills, where a strong increase in Late Bronze Age artefact scatters occurs – some of them associated with rectangular structures.
Aware that not all interpretative issues can be solved by intensifying archaeological research, I use non-systematic ethnographical observations in chapter 8 to fill gaps in our understanding of daily rural life in the Metal Ages. This gives insight in the occurrence of archaeological artefacts in sometimes very remote mountain locations, the size and quality requirements of agricultural land, the need for storage facilities, and the level of exchange and risk management among small-scale mixed farming groups. In chapter 9, I move to a broader scale and use the results presented in the previous chapters to evaluate current models for Italian Metal Age communities. I take four influential perspectives as my starting point: Graeme Barker’s model of minimally stratified agro-pastoralists (Biferno Valley); Marco Pacciarelli’s model of changing location preferences related to increasing socio-political complexity (Tropea peninsula); the territorial-hierarchical model of Renato Peroni based on emerging socio-political and socio-economical dependencies (Sibaritide); and Alberto Cazzella’s model in which the emergence of central places is explained by increasing craft specialization (Apulia). I show that the new data presented in this thesis can be applied to update these models in the following manner:
- New archaeological evidence from the Raganello upland valley is dated to the Neolithic, Chalcolithic and Early Bronze Age. This is an important contribution to our fragmentary knowledge about early farming communities in the Sibaritide.
- The role of the uplands and mountains in settlement and land use systems has long been discounted. This thesis shows that a persistent research bias in favor of large, central settlements in easily accessible landscape zones has resulted in a systematic underrepresentation of the hinterland in studies of pre- and protohistoric land use, whereas the earliest settlement traces are found there.
- In addition to Peroni’s model of ‘central’ settlements of several hectares in size, Metal Age settlement in the Sibaritide also has a rural dimension, consisting of single farmsteads with little or no access to the rare artefact groups that occur in large settlements.
- The large dolio a cordoni o a fasce storage vessels, clearly inspired by Eastern Mediterranean wares, are not among these rare artefact groups, since they occur in almost all rural Late Bronze Age sites in the Contrada Damale. This can be explained by reference to the need for storage facilities in small-scale farming communities to minimize risk and counter poor harvests, as observed in the ethnographical study in chapter 8.
- There is a strong increase in small-scale habitations in the foothills during the Final Bronze Age (ca. 1100-950 BC), which does not continue into the Early Iron Age (ca. 950-800 BC) and Full Iron Age (ca. 800-720 BC). This may be due to a visibility bias related to our inability to recognize EIA pottery wares, but could also result from a displacement of settlement into the coastal plain. This latter landscape zone was not studied in the present research because of its later thick sedimentation; a research bias that should be countered in future studies.
- Changes in social structure and settlement system after the Final Bronze Age are reflected in the introduction of a new burial custom. On Monte San Nicola, a combination of high-resolution field walking and magnetometry survey has resulted in the identification of most likely an urn field, radiocarbon dated to the EIA. This case is unique in Calabria, where only indirect evidence for cremation burials is known.
