Giotto e Galileu: novos olhares sobre o C\'eu e sobre o Livro da Natureza

Abstract

In this work, an attempt is presented to understand the contribution of Galileo Galilei in the field of the History of Ideas, from the moment he points a spyglass to the sky. For that, it was previously necessary that Giotto painting the sky in blue. We reconstruct this fascinating trajectory between the 13th and 17th centuries in Europe, relating different practices and knowledges, as well as discussing the scientific and philosophical thought of that time. The main thesis of this essay is to show that Giotto, who painted the sky blue in a culture that wanted it to be golden, followed a conceptual path very similar to that followed by Galileo centuries later.
