Unifying Heaven and Earth. Essays in the History of Early Modern Cosmology
One of the most significant events in the history of Western civilization was the cosmological revolution of the 16th and 17th centuries. Among the most salient factors in this change, described by Alexandre Koyré as the ‘destruction of the cosmos’ inherited from ancient Greece, were Copernican heliocentrism and the substitution of a homogeneous universe for the hierarchical cosmos of the Platonic and Aristotelian tradition. Starting with a new approach to the issue of the presence of Islamic astronomical devices in Copernicus’ work and a thorough reappraisal of the cosmological views of Paracelsus, the book deals mainly with the abolition of cosmological dualism and the ways in which it affected the decline of astrology over the 17th century. Other related topics include planetary order and theories of world harmony, the cause of planetary motion in the Tychonic world system or the discussion on comets in Germany through the first presentation of a manuscript treatise by Michael Maestlin on the great comet of 1618.
On Sunspots
Galileo’s telescopic discoveries, and especially his observation of sunspots, caused great debate in an age when the heavens were thought to be perfect and unchanging. Christoph Scheiner, a Jesuit mathematician, argued that sunspots were planets or moons crossing in front of the Sun. Galileo, on the other hand, countered that the spots were on or near the surface of the Sun itself, and he supported his position with a series of meticulous observations and mathematical demonstrations that eventually convinced even his rival. On Sunspots collects the correspondence that constituted the public debate, including the first English translation of Scheiner’s two tracts as well as Galileo’s three letters, which have previously appeared only in abridged form. In addition, Albert Van Helden and Eileen Reeves have supplemented the correspondence with lengthy introductions, extensive notes, and a bibliography. The result will become the standard work on the subject, essential for students and historians of astronomy, the telescope, and early modern Catholicism.

The Duke and the Stars
This study is the first to examine the important political role played by astrology in Italian court culture. Reconstructing the powerful dynamics existing between astrologers and their prospective or existing patrons, The Duke and the Stars illustrates how the “predictive art” of astrology was a critical source of information for Italian Renaissance rulers, particularly in times of crisis. Astrological “intelligence” was often treated as sensitive, and astrologers and astrologer-physicians were often trusted with intimate secrets and delicate tasks that required profound knowledge not only of astrology but also of the political and personal situation of their clients. Two types of a...

Regiomontanus: His Life and Work
The 500th anniversary of Regiomontanus's birth has occasioned this depiction of his life and work. It is the first English translation of Ernst Zinner's monumental biography, plus a number of specially-written supplementary articles which help paint a more comprehensive picture of the current state of knowledge about Regiomontanus. The articles show the high regard in which the biography is still held by the community of scholars doing work on the mathematics of the Renaissance.Zinner's biography is a mine of information about early printing, astrolabes, tables of eclipses and the world of Henry of Langenstein, Johann of Gmunden, Georg Peuerbach, Cardinal Bessarion, Nicholas of Cusa and the extraordinary itinerant scholar, Johannes Müller of Königsberg — Regiomontanus. His contributions to mathematics are discussed (for example, he may have discovered the fifth and sixth perfect numbers) as well as the mysteries surrounding his life and death.
