Mark Peterson makes an extraordinary claim in this fascinating book focused around the life and thought of Galileo: it was the mathematics of Renaissance arts, not Renaissance sciences, that became modern science. Galileo's Muse argues that painters, poets, musicians, and architects brought about a scientific revolution that eluded the philosopher-scientists of the day, steeped as they were in a medieval cosmos and its underlying philosophy.

According to Peterson, the recovery of classical science owes much to the Renaissance artists who first turned to Greek sources for inspiration and instruction. Chapters devoted to their insights into mathematics, ranging from perspective in painting to tuning in music, are interspersed with chapters about Galileo's own life and work. Himself an artist turned scientist and an avid student of Hellenistic culture, Galileo pulled together the many threads of his artistic and classical education in designing unprecedented experiments to unlock the secrets of nature.

In the last chapter, Peterson draws our attention to the Oratio de Mathematicae laudibus of 1627, delivered by one of Galileo's students. This document, Peterson argues, was penned in part by Galileo himself, as an expression of his understanding of the universality of mathematics in art and nature. It is "entirely Galilean in so many details that even if it is derivative, it must represent his thought," Peterson writes. An intellectual adventure, Galileo’s Muse offers surprising ideas that will capture the imagination of anyone—scientist, mathematician, history buff, lover of literature, or artist—who cares about the humanistic roots of modern science.

Between 1608 and 1610 the canopy of the night sky changed forever, ripped open by an object created almost by accident: a cylinder with lenses at both ends. Galileo’s Telescope tells the story of how an ingenious optical device evolved from a toy-like curiosity into a precision scientific instrument, all in a few years. In transcending the limits of human vision, the telescope transformed humanity’s view of itself and knowledge of the cosmos.

Galileo plays a leading—but by no means solo—part in this riveting tale. He shares the stage with mathematicians, astronomers, and theologians from Paolo Sarpi to Johannes Kepler and Cardinal Bellarmine, sovereigns such as Rudolph II and James I, as well as craftsmen, courtiers, poets, and painters. Starting in the Netherlands, where a spectacle-maker created a spyglass with the modest magnifying power of three, the telescope spread like technological wildfire to Venice, Rome, Prague, Paris, London, and ultimately India and China. Galileo’s celestial discoveries—hundreds of stars previously invisible to the naked eye, lunar mountains, and moons orbiting Jupiter—were announced to the world in his revolutionary treatise Sidereus Nuncius.

Combining science, politics, religion, and the arts, Galileo’s Telescope rewrites the early history of a world-shattering innovation whose visual power ultimately came to embody meanings far beyond the science of the stars.
