Abstract:

This presentation will discuss the inevitability of prediction in conservation activities.
Routine activities such as condition assessment and risk assessment rely on the ability to
predict future environments and future physical and chemical states of objects. Yet for the
results to be useful they have to be presented as positive statements that hide the huge
uncertainties in such predictions. Codes of conservation ethics imply predictions about the
future behaviours of people and objects. Despite the inherent uncertainties of such
predictions, such codes have become the bedrock of the conservation profession.

Abstract

In recent years, the study of ancient artifacts has moved beyond straightforward typologies, descriptions, and quantifications. New approaches to the analysis of material culture -  including methods of geospatial referencing, artifact agency, object biography, and statistical analysis of large datasets - have drawn attention to the myriad ways in which objects could be used and reused, deposited and redeposited in the ancient world. These new approaches have consequently given new life to materials that have been long overlooked in busy storerooms, from iron nails to loom weights, from ceramic wasters to unidentifiable coins. However, no matter the classification method, scholars still by and large fail to situate all the artifacts from a site fully within their archaeological contexts, a term that is frequently discussed in published reports but often thoroughly misunderstood. In both excavation publications and museum displays, the intended use of an object is almost always prioritized when in fact a contextual approach to the study and presentation of artifacts and assemblages can better illustrate the multiple, varied roles that objects served in the ancient world.

As the Manager of Data and Information Resources for the University of Cincinnati's Pompeii Archaeological Research Project: Porta Stabia (PARP:PS), the Data Supervisor for the American Excavations at Morgantina: Contrada Agnese Project (AEM:CAP), and the Head of Materials for the University of Cincinnati’s Tharros Archaeological Research Project (TARP), I have facilitated the development of a robust data organizational scheme that guides our innovative approach to material culture. I argue that by prioritizing context in the analysis of artifacts and assemblages, we can come to a more nuanced interpretation of how everyday objects were used, discarded, and recycled in urban spaces in antiquity. In my presentation, I’ll be highlighting some of the important lessons that I have learned along the way.

Abstract

Climate changes are a serious threat to cultural and natural heritage. Although many contexts are today seriously endangered, recent studies highlight how “archaeology and cultural heritage threatened by anthropogenic climate change are not just victims but part of the solution” (Hambrecht & Rockman, 2017. American Antiquity). Long-term archaeological projects could provide evidence to better understand the nature of the relations between climatically driven environmental changes and social trajectories. Aim of this talk is to present a synthesis of the main Holocene climate and environmental variations from a privileged geographical context – the central Sahara, where the magnitude of these changes was huge –, with a special focus on the Tadrart Acacus and Messak region (SW Libya). Here, cultural and social trajectories go together with resilient mechanisms of adaptations. Archaeological evidence reveals that social strategies were pivotal in coping with environmental changes. Although it is certainly true that climate changes are in fact central elements in cultural trajectories, in the past as today, this is even truer for marginal ecosystems such as the changing landscapes of the Holocene central Sahara. However, the continuity of many cultural practices until historical times and even later shows how the Saharan tradition is indeed an extraordinary way of life that deserves specific attention.

Early globalization? Isotopic evidence of food practices in Prehistoric Italy

The cultural and social importance of food goes far beyond the mere necessity of nutrition, yet archaeologists have been slow to tackle issues of the sociality of food in prehistory. This is a great loss particularly as the economic transformations, which structured human diet took place in prehistory. One reason for lack of attention to this question has been limited methodologies for investigating not only what foods were produced but also exactly what foods people consumed.

The increasing application of biomolecular investigations of skeletal tissues offers an exceptionally valuable approach for directly assessing aspects of an individual’s life, including their diet, geographical origin as well as the climate they inhabited.

In the Central Mediterranean a number of important economic questions can be addressed through isotopic investigations: we can explore the balance between plant and animal sources of food in the diet of prehistoric people and how this change between the onset of the Neolithic (ca. 6000 BC) and the end of the Bronze Age (ca. 900 BC). We can assess the relative contribution of marine resources to diet the Central Mediterranean and, further, we can identify mode and tempo for the use of new foods.

This talk will present new isotopic data on a large set of sites from prehistoric Italy that span from the earliest phases of the Neolithic to the later Bronze Age. A pattern of great complexity emerges, showing profound differences between the northern and southern regions of the Peninsula, which can be associated with environmental aspects but mostly should be interpreted as different cultural practices across space and time.
