Abstract
Philip II a patron of the sciences? This aspect of his turbulent reign, like many others, bas brought conflicting assessments. He bas been praised for his enterprise and blamed for isolating Spain from the scientific revolution. More information has now become available as a resuit of research on related themes, and it seems opportune to reconsider Philip's relations with the sciences. This has not attracted much attention outside of Spain because of the general neglect of the history of Spanish science. Yet Spain was no intellectual backwater—it had a rich scientific culture which was still alive in the sixteenth century. And the question of Philip's patronage is important since Castile had become the heart of the most powerful empire in the West at a time when Europe was experiencing a new phase of the Reformation and the beginnings of scientific revolution.
