The problem of tin in Mesopotamian bronzes

Abstract
Taking as its starting‐point papers by Dayton, and Muhly and Wertime, this paper tries to show that at least two sources of tin, one in Armenia and one near Bukhara, are known, and attempts to discover whether either of them could have been the source used by the Sumerians. The evidence is inconclusive but the indications are that Bukhara is a more likely source of supply in the third millennium.
