Is mined in part for the extraction of *silver from its ores. Some of the major sources in the Greek world were located at *Laurium in *Attica, on *Siphnos, and in *Macedonia. There were extensive workings in Anatolia (see asia minor). In the western Mediterranean, lead was mined on *Sardinia and in Etruria (see etruscans). Roman extraction took place in *Spain, *Gaul, and *Britain. Stamped lead ‘pigs’ show that lead was being extracted from the Mendips shortly after the Roman invasion of Britain (CIL 7. 1201). In the late empire lead mines were operating in the Balkans. Lead isotope analysis has allowed different sources to be identified. Thus lead from Archaic deposits in Laconia, as well as traces identified in Roman skeletal material from Britain, can be traced back to Laurium.Buildings associated with the extraction of silver from the argentiferous lead ore have been excavated at Laurium. Litharge (the by-product of this process) has been found in protogeometric and even bronze age contexts. In the Greek world lead was used to form the core of bronze handles, to fix steles to their bases, and for small offerings (such as those found in the sanctuary of *Artemis Orthia at *Sparta).
