By the 3rd millennium the value of copper and its various alloys as a material for all kinds of useful objects was being understood in the communities throughout the Middle East. Raw copper was readily available to these communities at a number of sources on the Iranian Plateau and in the Oman peninsula. This selection of objects span from the late fourth millennium BCE until the Medieval period. Through them we can track the development of the technologies of metallurgy and the movement of this vital raw material across the landscape. The sites represented by these objects are Bronze Age Hissar, Iron Age Hasanlu and Medieval Rayy.
