Tradiciones de cambio y observación tradicionalista en los albores de la cosmología europea en la Nueva España

The present text studies the introduction and development of European celestial conceptions in New Spain in the 16th and early 17th centuries. Although these notions used to be the usually accepted at the time, the origins of some of the first cosmological novelties are sought for. More precisely, it is examined how two basic ideas of the peripatetic cosmology began to be questioned: the sharp distinction between the celestial and the earthly region, and the existence of celestial spheres that carry the stars with them. In this way, the possible sources of the first changes to these predominant notions are tracked studying mainly, on the one hand, the epistemic concept of the dialectic developed at the time and, on the other, the use of experience and observation, to analyze later their respective contributions to the first innovations in the celestial notions in New Spain.
