The Ptolemaic system of the universe, with the earth at the center, had held sway since antiquity as authoritative in philosophy, science, and church teaching. Following his observations of the heavenly bodies, Nicolaus Copernicus (1473-1543) abandoned the geocentric system for a heliocentric model, with the sun at the center. His remarkable work, On the Revolutions of Heavenly Spheres, stands as one of the greatest intellectual revolutions of all time, and profoundly influenced, among others, Galileo and Sir Isaac Newton.

An accessible, abridged edition with a new introduction. Renaissance Natural philosopher Nicolaus Copernicus's pioneering discovery of the heliocentric nature of the solar system is one of the few identifiable moments in history that define the understanding of the nature of all things. His great work was the consequence of long observation and resulted in the first stage of the Scientific Revolution by correctly positing that the earth and other planets of the solar system revolved around the sun. Not only did this promote further study to understand the place of humanity in the world and the universe, it questioned the authority of the organised Christian Church in the West to be the keeper of fundamental truths. Ultimately this would lead to the Enlightenment, and the separation of religion, government and science. The FLAME TREE Foundations series features core publications which together have shaped the cultural landscape of the modern world, with cutting-edge research distilled into pocket guides designed to be both accessible and informative.

Unlike some other reproductions of classic texts (1) We have not used OCR(Optical Character Recognition), as this leads to bad quality books with introduced typos. (2) In books where there are images such as portraits, maps, sketches etc We have endeavoured to keep the quality of these images, so they represent accurately the original artefact. Although occasionally there may be certain imperfections with these old texts, we feel they deserve to be made available for future generations to enjoy.

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.
