The Use of Balances in Late Andean Prehistory (ad 1200–1650)

Studies of balances (scales) in Europe, Asia and northern Africa have found that their use is not exclusively tied to state control or market exchange, but rather grew and evolved through interactions among bureaucrats in centralized states, merchants, artisans and local leaders. Research on balances from Andean South America can contribute to an understanding of the diverse roles and functions of balances, as they developed independently in a region where there were both exchange-based and non-market economies. This article includes data on Andean balances that reveal that they were used as early as the Late Intermediate Period (ad 1100–1400), and that there is variation in the characteristics and dimensions of the balances. Similar to other regions, balances in the Andes were likely used by different groups of specialists including merchants, bureaucrats and artisans. To understand how balances were used, they need to be understood alongside long-distance exchange practices, socio-political strategies, the organization of craft production and the possible use of currency.
