This contribution demonstrates the benefits of a transatlantic history of early modern mining that encompasses both a cross-pollination of approaches and a critical reexamination of the field’s underlying assumptions. It applies to Álvaro Alonso Barba’s 1640 El arte de los metales conceptual frameworks developed by historians of early modern European mining, by scholars of labor and science in the colonial Andes, and by theorists of reader reception and scholarly practice. This analysis offers a revised understanding of Pamela Long’s model of (...) the “trading zone” as a vision of knowledge production promoted by elite Europeans and shaped by the dialogic model of knowledge production taught at European universities. Parallels between Barba and the German humanist and metallurgical author Georg Agricola (1494–1555) underscore the applicability of these findings with respect to Barba for early modern mining more generally.
