ABSTRACT The Portuguese and Spanish empires were both global and long lasting. This essay focuses on colonial Spanish America, particularly on the practices of natural history. It also suggests that chivalric‐epic ideologies permeated early modern epistemologies, including those of the French and the British. The essay criticizes the application of nineteenth‐century models of empire to the understanding of the early modern composite monarchies in the New World. Finally, it explores the ways metropolitan natural philosophy was transformed in the New World (...) kingdoms to bolster patriotic identities. (shrink)
