text: In Mesopotamia, from –2750 BC, the lost-wax technique was used for small-scale, and then later large-scale copper and bronze statues. One of the earliest surviving lost-wax castings is a small lion pendant from Uruk IV. Sumerian metalworkers were practicing lost-wax casting from approximately –3200 BC. Much later examples from northeastern Mesopotamia/Anatolia include the Great Tumulus at Gordion (late 8th century BC), as well as other types of Urartian cauldron attachments.
