"Safier’s engaging and significant book is several narratives in one. It is an important contribution to recent historiographical revisionism centring around geographical readings of (the) Enlightenment. . . .This is an account, finely told throughout, of mapping in the field, of mapping as an uncertain form of topographic depiction and measurement—and of ethnographic classification, since later commentators sought to ‘fix’ Amerindians as native ‘others’ even as they were dependent upon them as guides and informants—and of the ways in which eighteenth-century mapmakers had to reconcile different epistemological standards in order to make distant worlds portable in map form. Safier’s book is an important addition to case studies in the social and technical history of Enlightenment mapping as a process that had less to do with the unproblematic extension of European certainty and more with the contingencies of geography, locally, nationally and as networks of transnational exchange and interaction."
