One of the most crucial elements in the dynamics of the Late Bronze Age metals trade in the Mediterranean was the production and exchange of copper 'oxhide' ingots (Knapp & Cherry 1994). These are basically flat, oblong slabs of nearly pure and unalloyed copper that weigh between 10 and 40 kg. The majority has an average weight of c. 29-30 kg however, and as a result this 'standard' has been traditionally equated with the existence of a 'talent'. They furthermore form a prominent part of the bulk cargo in shipwrecks discovered at Ulu Burun and Cape Gelidonya (Gale 1991). The results of an extensive programme of lead-isotope analyses aimed at determining the provenance of these ingots have led some archaeologists to propose that most of the ingots were produced from the rich copper resources on the island of Cyprus. Based on the same results, the Oxford group has also discussed the possibility of a specialized centre for their production in the Skouriotissa region of the island (Stos-Gale et ~ l . 1997
