In 1543, Nicolaus Copernicus publicly defended his hypothesis that the earth is a planet and the sun a body resting near the center of a finite universe. But why did Copernicus make this bold proposal? And why did it matter? The Copernican Question reframes this pivotal moment in the history of science, centering the story on a conflict over the credibility of astrology that erupted in Italy just as Copernicus arrived in 1496. Copernicus engendered enormous resistance when he sought to protect astrology by reconstituting its astronomical foundations. Robert S. Westman shows that efforts to answer the astrological skeptics became a crucial unifying theme of the early modern scientific movement. His interpretation of this long sixteenth century, from the 1490s to the 1610s, offers a new framework for understanding the great transformations in natural philosophy in the century that followed.

An account of the Copernican Revolution, focusing on the significance of the plurality of the revolution which encompassed not only mathematical astronomy, but also conceptual changes in cosmology, physics, philosophy, and religion.

In 1984, Noel Swerdlow and Otto Neugebauer argued that Nicolaus Copernicus (1473–1543) explained planetary motion by using mathematical devices and astronomical models originally developed by Islamic astronomers in the thirteenth and fourteenth centuries. Was this a parallel development, or did Copernicus somehow learn of the work of his predecessors, and if so, how? And if Copernicus did use material from the Islamic world, how then should we understand the European context of his innovative cosmology? Although Copernicus’s work has been subject to a number of excellent studies, there has been little attention paid to the sources and diverse cultures that might have inspired him. Foregrounding the importance of interactions between Islamic and European astronomers and philosophers, Before Copernicus explores the multi-cultural, multi-religious, and multi-lingual context of learning on the eve of the Copernican revolution, determining the relationship between Copernicus and his predecessors. Essays by Christopher Celenza and Nancy Bisaha delve into the European cultural and intellectual contexts of the fifteenth century, revealing both the profound differences between “them” and “us,” and the nascent attitudes that would mark the turn to modernity. Michael Shank, F. Jamil Ragep, Sally Ragep, and Robert Morrison depict the vibrant and creative work of astronomers in the Christian, Islamic, and Jewish worlds. In other essays, Rivka Feldhay, Raz Chen-Morris, and Edith Sylla demonstrate the importance of shifting outlooks that were critical for the emergence of a new worldview. Highlighting the often-neglected intercultural exchange between Islam and early modern Europe, Before Copernicus reimagines the scientific revolution in a global context.

Controversial at the time, Copernicus's discoveries led to the scientific revolution, and a greater understanding of our place in the universe. 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.

In May, 1539, a young, German mathematician named Georg Joachim Rheticus traveled hundreds of miles across Europe in the hopes of meeting and spending a few days with the legendary astronomer, Nicolas Copernicus, in Frombork, Poland. Two and a half years later, Rheticus was still there, fascinated by what he was discovering, but largely engaged in trying to convince Copernicus to publish his masterwork-De revolutionibus (On the Revolutions of the Heavens), the first book to posit that the sun was the center of the universe. That he was finally able to do so just as Copernicus was dying became a turning point for science and civilization. That he then went on to a legendary career of his own-he founded the field of trigonometry, for example-will be one of the many surprises in this eye-opening book, which will restore Rheticus to his rightful place in the history of science.
