"Peterson, a Professor of Physics and Mathematics, explains the book’s origins: The beginnings of this project were some observations about mathematics and the arts in the late Middle Ages and early Renaissance. I was especially intrigued by some mathematical ideas that I had noticed in Dante, unexpected mathematical sophistication centuries before Galileo. I also became fascinated with Galileo, and I began to wonder where he had come from. This question seemed to organize my thoughts. What was Galileo’s intellectual inheritance, and how did it form him? Galileo’s education was in the humanities and the arts, so the question is a sprawling one. And even that is not enough, because Galileo’s ultimate enthusiasm was for mathematics, and that is another broad intellectual stream. Where all these streams mixed, that is where Galileo came from, or so I imagined. To understand it, I had to follow the streams back to their sources. The book summarizes the classical legacy in mathematics and the sciences, and contains chapters on the Renaissance arts of poetry, painting, music, and architecture. We learn, for instance, that Galileo’s favorite poem was Orlando Furioso, Ludovico Ariosto’s epic of love, chivalry, and madness. The thread connecting the book’s sections, writes Peterson, is mathematics: “Implicitly I ask, what did mathematics mean for the arts? And what did the arts mean for mathematics?” - Amira

I still don't understand what the claim is? 'Mathematics of Renaissance arts'? Like perspective and golden ratio and junk? - Eivind
