Lading of the Late Bronze Age ship at Uluburun

Lin, Shih-Han Samuel 29 August 2012 (has links)
The Uluburun shipwreck was discovered in 1982 when a Turkish sponge diver informed the Institute of Nautical Archaeology (INA) of his discovery of metal biscuits with ears. INA archaeologists recognized this as a description of oxhide ingots, a clear indication of a Late Bronze Age site. This find was of considerable interest as very little is known about seafaring, long distance trade, and ship construction during the Late Bronze Age, except for a glimpse provided by the Cape Gelidonya shipwreck excavated in 1960 by George Bass. The site at Uluburun revealed only a handful of disarticulated ship fragments; nevertheless, a meticulous study of these timbers and the distribution of the cargo and shipboard items on the seabed resulted in a hypothetical, but carefully guided, reconstruction of the ship and the lading of its cargo. The artifacts recovered from the Uluburun shipwreck are unlike those discovered on land in quality of preservation as well as the quantity found. Items pertinent to this study include 354 copper oxhide ingots (approximately 10 tons), 152 copper bun ingots (nearly 1 ton), 110 tin ingot fragments (approximately 1 ton), 175 glass ingots (approximately 0.3 tons), 150 Canaanite jars (approximately 2 tons if filled with water), 10 large storage jars (pithoi) (approximately 3.5 tons if filled with water), approximately 51 Canaanite pilgrim flasks, 24 stone anchors (3.3 tons), nearly 1 ton of ballast stones, and the hull remains itself. Two computer programs, Rhinoceros and PHASER, were used to visually model the artifacts and ship in three-dimensions and to systematically test various hull shapes and lading arrangements in a range of hydrostatic conditions. Tests showed that a hull measuring 15 x 5 x 2 m would be capable of carrying the estimated 20 tons of cargo and shipboard items recovered from the wreck at a draft of 1 m, with sufficient freeboard to allow six passengers to stand on one side of the vessel without compromising the stability of the ship. / Institute of Nautical Archaeology

The place of lead in an Egyptian port city in the Late Period

van der Wilt, Elsbeth M. January 2013 (has links)
This thesis analyses a range of lead objects discovered in Thonis-Heracleion, an Egyptian port city, and offers a new perspective on the use of metals in antiquity. It advances two central arguments: firstly, that the large quantity of lead artefacts in Thonis-Heracleion is not exceptional but rather a more accurate reflection of the metallisation of ancient societies and secondly, that the corpus of lead objects sheds light on aspects of ancient communities that normally remain invisible due to the ease of recycling and low cost of lead. The first chapter reviews the presence of lead in the archaeological record in Egypt, the factors affecting its deposition and preservation, and the corpus as a whole from Thonis-Heracleion. A comparison between the two puts the lead from the site in a new Egyptian perspective. The second, third, and fourth chapters offer substantial analyses of lead ingots, weights, and containers found at Thonis-Heracleion with parallels from around the Mediterranean. The chapters show the potential of this corpus to shed light on activities in the Egyptian town despite the notable lack of direct parallels. It becomes clear for example that large lead objects appear earlier in the archaeological record and that the range of objects is wider than previously suspected. The analysis in these chapters offers a robust dating framework for lead objects previously unavailable. Together the lead artefacts illustrate local mercantile activities, the economic role of the port city, and, through the identification of the first Athenian weights found in Egypt, trade connections between Egypt, Athens, and the rest of the Eastern Mediterranean. The result is an overview of lead in Egypt and its place in Thonis- Heracleion, demonstrating the significance of metals for understanding ancient societies.
