Aridity and Adaptation among Arabian Bronze Age Communities: Investigating Mobility and Climate Change Using Isotope Analysis
Lesley A. Gregoricka, University of South Alabama

The rapid aridification of southeastern Arabia at the end of the Umm an-Nar period (2700-2000 BCE) coincided with mater changes in material culture and social organization demarcating the subsequent Wadi Suq period (2000-1600 BCE). However, climate change has rarely been directly observed in the tissues of the people who themselves experienced it. Here, stable oxygen isotopes from the dental enamel of those interred in monumental third and second millennia BCE tombs at the Shimal Necropolis in the United Arab Emirates were used to evaluate shifts in climate. Strontium and carbon isotope values were similarly investigated to assess the impact of an increasingly arid climate on mobility patterns and dietary intake. These isotopes reveal regional aridification over time, but also continuity in lifestyle, suggestive of a resilient community that sought to maintain their way of life in the face of environmental change.

Lesley A. Gregoricka

Dr. Lesley A. Gregoricka is an Associate Professor at the University of South Alabama in Mobile. She holds degrees in anthropology from Ohio State University (MA and PhD) and the University of Notre Dame (BA). Her areas of specialization include bioarchaeology, forensic science, Bronze and Iron Ages, and isotopic analyses of mobility, climate change, and diet in Arabia and the southern Levant. Professor Gregoricka’s has recently co-edited several volumes including Mortuary and Biological Perspectives on the Bronze Age in Arabia (University Press of Florida) and Purposeful Pain: The Bioarchaeology of Intentional Suffering (Springer). She currently co-directs a multi-year National Science Foundation project focusing on the biolarchaeology of Bronze Age social systems.

“Sardis: Recent Discoveries from the Bronze Age until the End of Antiquity”
Nicholas D. Cahill, University of Wisconsin-Madison

The Archaeological Exploration of Sardis expedition has carried out large-scale, scientific excavations at the site in western Turkey since 1958. Over these 5+ decades, archaeologists have documented the emergence and development of Sardis, capitol of the Lydian Empire of the 7th and 6th centuries BCE, and of one of the great cities of the ancient world. Utilizing spectacular aerial imagery, Dr. Nicholas Cahill, Director of the Sardis Expedition since 2008, will discuss the geography, history and challenges of excavating such a large and complex site and will provide a backdrop for understanding recent discoveries and research. The speaker will address current archaeological questions including: Who were the Lydians that built Sardis as the capitol of their ancient kingdom? What does the early development of the city look like? What cultural transformations are evident when the native capitol becomes a Greek polis? What can the collapse of Sardis tell us about the “End of Antiquity” in the 7th c AD? On-going site conservation efforts will also be featured.

Nicholas Cahill

Dr. Nicholas Cahill is Professor of Greek and Roman Art and Archaeology in the Department of Art History at the University of Wisconsin-Madison. Since 2008 he has directed the Archaeological Exploration of Sardis expedition, overseeing both fieldwork and serving as the series editor of the Sardis Reports, Monographs, and Studies series. He holds advanced degrees from the University of California-Berkeley (MA and PhD) and has areas of specialization in Greek & Roman art and archaeology; Anatolian art and archaeology; Greek city planning; interrelationships between Greece and the Near East; Achaemenid Persia; and Greek epigraphy. Professor Cahill’s publication projects include Household and City Organization at Olynthus (Yale University Press, 2002), co-authorship of The City of Sardis: Approaches in Graphic Recording (Harvard University Art Museums, 2003), and editor of Love for Lydia. A Sardis Anniversary Volume Presented to Crawford H. Greenewalt, jr. (Sardis Report 4, 2008).

Sneak Preview of Spring Programs

We have several outstanding lectures lined up for the upcoming Spring program.

First up, on February 6th, long-time Milwaukee AIA member and officer, and Professor Emerita at Marquette University, Dr. Alice Kehoe, will presents a lecture entitled: “Traveling Prehistoric Seas: Boats, the Ocean and Archaeology Evidence for Precolumbian Voyages.” Dr. Kehoe will present the history of seafaring people crossing large expanses of open ocean to colonize Indonesia and Australia as a background for discussing the evidence for Polynesian explorers reaching the Americas.

On March 6th, Dr. Chris Fisher, Colorado State University, will present “The Application of LiDAR Scanning for the Documentation of Ancient Cities and Regions.” He will discuss how LiDAR results provide evidence of site organization at Angamuco in Michoacán and revealed regional settlement patterns within the Mosquitia tropical wilderness in Honduras. LiDAR is a type of remote sensing that uses pulses of laser light to measure distances and uncover hidden landscape and architectural features.

We are very much hoping that in-person lectures will be possible in the Spring.
