This article seeks to revise the common scholarly assumption that in early modern Europe there was no single word for the study of the universe as a whole until the word “cosmology” appeared in Christian Wolff’s Cosmologia generalis methodo scientifica pertractata (1731). In fact, the term “cosmology” had circulated in both Latin and European languages since at least the 1530s in the context of critical appraisals of the largely dominant Aristotelian and scholastic frameworks. The aim of this study is to (...) unearth the earliest attempts to define cosmology as a philosophical discipline and, thereby, to highlight the lasting authority of traditional disciplinary boundaries.

Copernicus’s De revolutionibus and Girolamo Fracastoro’s Homocentrica were both addressed to Pope Paul III. Their dedicatory letters represent a rhetorical exercise in advocating an astronomical reform and an attempt to obtain the papal favour. Following on from studies carried out by Westman and Barker & Goldstein, this paper deals with cultural, intellectual and scientific motives of both texts, and aims at underlining possible relations between them, such as that Copernicus knew of Fracastoro’s Homocentrica, and that at least part of the (...) rhetorical strategy laid out in De revolutionibus’s dedicatory letter can be read as a sophisticated response to Fracastoro’s arguments.Keywords: Copernicus; Fracastoro; Paul III; History of astronomy; Patronage.
