(May 2007) Michael Rice Jones, B.A., Boston University Chair of Advisory Committee: Dr. Cemal Pulak The production and trade in copper and bronze was one of the major features of the complex societies in the Near East and Mediterranean during the third to first millennia B.C. While finished metal objects are common finds from the period, ancient metal ingots and hoards of scrap metal, as well as archaeological evidence of metallurgical activities, are often more important sources of information for how ancient technology and trade functioned. Shipwrecks, particularly those found off the coast of Turkey at Uluburun and Cape Gelidonya, as well as mining and smelting sites in the Mediterranean region, provide invaluable information on the production and trade of copper and tin, the main ingredients of bronze. In this thesis, I examine the evolution of the copper trade in the eastern and central Mediterranean, particularly during the Late Bronze Age, when ‘oxhide’ ingots were widely exported. Finds of oxhide ingots have increased dramatically in recent years, and no synthesis of all of this newly available evidence is currently available. I attempt to analyze this new evidence in relation to older finds and research, with a particular focus on the cargo of the Uluburun shipwreck, the largest collection of Bronze Age metal ingots from a single site in the Mediterranean. The history of oxhide ingot production is complex, but by the Late Bronze Age Cyprus was supplying much of the copper used to neighboring regions, with revolutionary effects on societies in Cyprus and elsewhere. iv The archaeological evidence shows that oxhide ingots are early examples of a standardized industrial product made for export by emerging state-level societies during the second millennium B.C. and fueled the development of international trade, metallurgical technology, and complex social institutions in a variety of Mediterranean societies from Egypt and the Levant, Greece, Cyprus, to Sardinia in the central Mediterranean. v ACKNOWLEDGMENTS I would like to thank my committee members, Dr. Cemal Pulak, Dr. Shelley Wachsmann, and Dr. Cristoph Konrad. Cemal Pulak and George Bass’ work on the Uluburun shipwreck first stimulated my interest in the topic of the metals trade in the Bronze Age Mediterranean several years before I enrolled in Texas A&M, and their publications on Bronze Age Mediterranean shipwrecks and Bronze Age trade have been extremely valuable in researching this thesis. I am particularly indebted to Dr. Pulak, my committee chair, for giving me the opportunity to travel to Turkey in the summers of 2003 and 2004 and from June to December of 2005 to assist in several research projects, including the study of the copper ingots from the Uluburun shipwreck. This experience has been invaluable in understanding the Uluburun site, the literature on Bronze Age metals, and the problems associated with reconstructing the metals trade in the Bronze Age. I would like to thank Shelley Wachsmann for his enthusiastic and imaginative approach to teaching about ancient trade and seafaring in the Mediterranean. Two of Dr. Wachsmann’s books, Aegeans in the Theban Tombs and Ships and Seafaring in the Bronze Age Levant, have also been particularly valuable reference works for this thesis. Dr. Pulak has also provided access to unpublished artifact catalogs, excavation notes, photographs, and other materials related to the Uluburun site which were invaluable for the discussions of the physical characteristics of Bronze Age copper ingots and the vi technology involved in ancient smelting, refining, and casting of metal ingots. I am indebted to the many students and colleagues of Dr. Pulak who have contributed to this material since the site’s discovery in 1982, though I personally know only the most recent contributers from the Nautical Archaeology Program at Texas A&M University. Appendix B, a description of terms used in the physical description of oxhide and bun ingots from the Uluburun ship, is based on work by myself and Tom Larson, under the guidance of Cemal Pulak, during the summer of 2003. Tom also worked extensively on the organization and artifact descriptions of the copper oxhide and bun ingot catalogs. Sam Lin was a major contributer to the work on the copper bun ingots. Mark Polzer assembled the oxhide and bun ingot catalogs in their current form, including the scanning of hundreds of artifact photos, while Wendy van Duivenvoorde recently completed the latest revisions and reorganization of the tin ingot catalog. I would also like to thank the staff at the Bodrum Museum of Underwater Archaeology in Bodrum, Turkey, for their assistance during my periods of work on the Uluburun ingots at the museum in July and August of 2003 and 2004, and in October of 2005. Conservation work performed at the Bodrum Museum, under the Institute of Nautical Archaeology (INA), since the excavation of the Uluburun wreck has made a detailed study of the metal ingots from the wreck possible. Finally, I would like to thank my parents, who since childhood have always encouraged my interest in archaeology. vii TABLE OF CONTENTS Page ABSTRACT ...................................................................................................... iii ACKNOWLEDGMENTS................................................................................. v TABLE OF CONTENTS .................................................................................. vii LIST OF FIGURES........................................................................................... x LIST OF TABLES ............................................................................................ xiii CHAPTER I INTRODUCTION.

  • Hittite Empire Centered in Asia Minor Came to an End When Barbarian Hordes from Thrace Swept Over the Western Lands and C
    The Doctrine of the Hittite The term Hittite has a twofold use in the OLD TESTAMENT. Usually it designates a relatively unimportant ethnic group living in Palestine since the days of the patriarchs. (Gen 15:19-21). These people, called the "sons of Heth," were descended from Noah's son Ham through Canaan (Gen 10:15; 1Ch 1:13) and were settled in the central hills of Palestine. (Num 13:29; Jos 11:3) In a few cases, however, the term Hittite is used in the OLD TESTAMENT to designate outsiders, non-Semitic peoples living in the north, who were to be respected and feared as a great power. (1Ki 11:1; 2Ki 7:6-7; 2Ch 1:17). These were the Hittites so famous from extrabiblical historical sources. Although it has been suggested that the small enclaves of Hittites in central Palestine were part of the northern Hittites who migrated south early in the 2nd millennim B.C., there need be no connection between the two groups at all, except for a coincidental similarity of name. The Indo-European Hittites who entered Anatolia (Turkey) and the Near East around 2000 from the steppes of inner Asia received their name more or less by accident, by virtue of the fact that they settled in territory previously held by an earlier non-Indo- European group called Hatti-people (or Hattians). Henceforth in this doctrine the three groups will be called "sons of Heth," "Hittites," and "Hattians" respectively, to avoid confusion. The red and black highly burnished Khirbet Kerah products found in Palestine are virtually identical with pottery in central Anatolia and the Kurgan homeland in Transcaucasia in the 3rd millennium B.C.

  • From Small States to Universalism in the Pre-Islamic Near East
    REVOLUTIONIZING REVOLUTIONIZING Mark Altaweel and Andrea Squitieri and Andrea Mark Altaweel From Small States to Universalism in the Pre-Islamic Near East This book investigates the long-term continuity of large-scale states and empires, and its effect on the Near East’s social fabric, including the fundamental changes that occurred to major social institutions. Its geographical coverage spans, from east to west, modern- day Libya and Egypt to Central Asia, and from north to south, Anatolia to southern Arabia, incorporating modern-day Oman and Yemen. Its temporal coverage spans from the late eighth century BCE to the seventh century CE during the rise of Islam and collapse of the Sasanian Empire. The authors argue that the persistence of large states and empires starting in the eighth/ seventh centuries BCE, which continued for many centuries, led to new socio-political structures and institutions emerging in the Near East. The primary processes that enabled this emergence were large-scale and long-distance movements, or population migrations. These patterns of social developments are analysed under different aspects: settlement patterns, urban structure, material culture, trade, governance, language spread and religion, all pointing at population movement as the main catalyst for social change. This book’s argument Mark Altaweel is framed within a larger theoretical framework termed as ‘universalism’, a theory that explains WORLD A many of the social transformations that happened to societies in the Near East, starting from Andrea Squitieri the Neo-Assyrian period and continuing for centuries. Among other infl uences, the effects of these transformations are today manifested in modern languages, concepts of government, universal religions and monetized and globalized economies.

  • The Uluburun Shipwreck – a Dendrochronological Scandal
    The Uluburun Shipwreck – a Dendrochronological Scandal During the Late Bronze Age a trading ship was wrecked off the promontory of Kaş, near Uluburun, in southwestern Turkey. Work on its excavation began in 1984 and the wreck has proved to be a gift to archaeologists. Its cargo included Mycenaean and Cypriot pottery, Canaanite storage jars filled with resin, copper and tin ingots, tools, fishing equipment, weapons, stone artefacts, gold and silver jewellery and a unique gold scarab bearing the name of the Egyptian queen Nefertiti. For more details, photographs and bibliography see online articles by the Institute of Nautical Archaeology on the “Bronze Age Shipwreck Excavation at Uluburun” and “Continuing Study of the Uluburun Shipwreck Artifacts”. As all their contents sank together, shipwrecks like this are veritable “time- capsules”. Excepting occasional problems involving antiques or possible antiques, rich multi-cultural cargoes like that of Uluburun provide invaluable evidence for refining the relative archaeological chronologies of neighbouring regions. Shipwrecks also hold the promise of offering absolute dates for their cargoes, if timbers from the ship can be reliably cross-dated with a well established dendrochronology. In 1996 Peter Kuniholm, Director of the Aegean Dendrochronology Project at Cornell University announced (in preliminary form) a result for Uluburun, in a article published in the prestigious journal Nature (Kuniholm et al. 1996, 782): Wood found as part of the cargo on Kaş/Uluburun shipwreck has a last preserved ring at 1316 BC; other finds include Mycenaean pottery from Greece (the most recent material present is early Late Helladic IIIB; J. B. Rutter, personal communication), and a unique gold scarab of Nefertiti, wife of Akhenaten, pharaoh of Egypt.
