It is generally agreed that the first black athlete to compete and win a medal in the Olympic Games was George Poage, an American, who was awarded a bronze medal in the 400m hurdle. It was 1904, the third modern Olympics since the games had been resurrected by Pierre de Coubertin in 1896. In the same afternoon, another AfricanAmerican, Joseph Stadler, received a silver medal for the high jump e...

The discovery of three small obsidian flakes at the Camel Site in the central Negev, Israel, constitutes the first discovery of obsidian in Early Bronze Age contexts in the Negev and Sinai. Obsidian hydration analysis and X-ray microprobe analysis confirm the association of the artifacts with the site and the period, and indicate origins in Eastern Anatolia, in significant contrast to the exclu...

Lead isotopic ratios of cassiterite, the dominant tin ore, evolve after crystallization through decay of uranium and thorium to lead. We show that the lead isotopic ratios of smelted tin at Rooiberg, South Africa, form an isochron that matches the known geological age of the Rooiberg cassiterite deposits. Since the lead isotopic ratios of several prehistoric tin and bronze artifacts throughout ...

We have investigated by numerical simulation the density segregation of fine equal-sized bronze and glass particles subject to vertical vibrations. The model was found to be capable of predicting the two main segregation forms ("bronze on top" and "sandwich") in roughly the same regions of the phase diagram as was found experimentally by Burtally We investigated the effects of pressure air forc...

Here we report the unprecedented discovery of the skeleton of a ritually interred donkey with a metal horse bit in association with its teeth and saddlebag fastenings on its back. This discovery in the Middle Bronze Age III sacred precinct (1700/1650-1550 BCE) at Tel Haror, Israel, presents a unique combination of evidence for the early employment of equid harnessing equipment, both for chariot...

Hydrogenation of unsaturated organosulfur compounds is an essential process through which these species are converted into cleaner and more useful compounds. Hydrogen bronze materials have been demonstrated to be efficient catalysts in hydrogenation of simple unsaturated compounds. Herein, we performed density functional theory calculations to investigate hydrogenation of thiophene on hydrogen ...

Currently, there are some 222 records in the Nottinghamshire Sites and Monuments Record (SMR) which are relevant to the First Millennium B.C. These records include 19 finds of Late Bronze Age metalwork, 5 examples of Iron Age metalwork, 9 find-spots of Iron Age coins, 57 find-spots of pottery ascribed to the Late Bronze Age and Iron Age, 21 finds of other objects ascribed to these two periods, ...

This paper explores the origins of the Nataraja cult in the state of Tamil Nadu in southern India. The trajectory of the dancing Shiva is traced: from the processional worship of metal icons outside the sanctum to the cultic elevation of the Nataraja bronze into the sanctum at Chidambaram. Archaeometallurgical, iconographic and literary evidence discussed shows that the Nataraja bronze, depicti...

Recent excavations at Pecica Şanţul Mare from 2006-2009 have produced a large and representative faunal assemblage from Dacian and Bronze Age contexts. In both periods, livestock husbandry was by far the most important source of meat, with hunting and trapping game, F shing, and collecting mollusks contributing secondarily. However, there are signiF cant diw erences between Iron and Bronze Age ...

BACKGROUND One of the main concerns for archaeo-metallurgists and archaeologists is to determine to what extent ancient craftsmen understood the effect of metal alloy composition and were able to control it in order to produce objects with the most suitable features. This problem can be investigated by combining compositional analyses of a high number of ancient artefacts with correlation analy...
