**New to Penguin Classics, the astonishing story of the Copernican Revolution, told through the words of the ground-breaking scientists who brought it about ** In the late fifteenth century, it was believed that the earth stood motionless at the centre of a small, ordered cosmos. Just over two centuries later, everything had changed. Not only was the sun the centre of creation, but the entire practice of science had been revolutionised. This is the story of that astonishing transformation, told through the words of the astronomers and mathematicians at its heart. Bringing together excerpts from the works and letters of Copernicus, Galileo, Kepler, Descartes, Newton and others for the first time, *The Dawn of Modern Cosmology* is the definitive record of one of the great turning points in human history.
