In contrast to the constellation figures in Hyginus and Abu Ma’shar, Piccolomini created a star atlas, measuring the positions of the stars according to an indicated scale (specific to each plate). He designated stars by Roman letters (a, b, c, etc.) in order of apparent brightness.

Copernicus argued that the Sun rather than the Earth lies in the center of the universe. The Earth moves as a planet around the Sun, carrying its Moon along as a satellite. In 1543 little proof was available that the Earth moves; there were many reasons not to accept it.

This is a replica of a microscope that is very much like one of the microscopes Galileo might have created. Indeed, it was once believed to have been made by Galileo, but is now attributed to Campani.

This landmark work by Albrecht Dürer presents several variations on the technique of “Alberti’s window.” Here the artist is creating a drawing of a lute with true perspective by means of a string drawn from the object, through the canvas window, to the vanishing point on the wall.

This beautiful work by Sirigatti, published in 1596, brings the tradition of perspective drawing up to Galileo’s time. Sirigatti was a member of the Academy of Drawing (Accademia del Disegno), a school for artists and engineers where Galileo studied as a young man.

This book is without doubt the most handsome anatomical work of the 16th century. Vesalius was fortunate to team up with Jan Stephan van Calcar, a world class artist. Even the human skeletons reveal an aesthetic appreciation of the human body.

From childhood, Galileo’s world was shaped by music. His father, Vincenzo Galilei, was a prominent music theorist who contributed to the development of Italian opera. This book, Vincenzo’s major work, was acquired in Fall 2014 with assistance from the Athletics Department.

When Galileo needed to purchase plates of brass to make his engineering compass or commissioned glass to make better lenses, metalsmith, assayers and craftsmen in Venice employed operations similar to those described in Birunguccio’s metallurgical manual.

Della Porta’s portrayal of a lynx on the title page of this and other works inspired Cesi with the name for his own Academy. Here, della Porta announced the existence of the Accademia Secretorum Naturae, an academy he founded in Naples cx. 1580 with the aim of discovering the secrets of nature...

What sports did they play in ancient Greece and Rome? This book by a leading physician of the Renaissance attempts to answer that question. Mercuriale once recommended Galileo for a university position.

Gallucci, a Venetian scholar, was interested in astronomical instruments, both physical and on paper. The “Theater of the World” features a parade of rotating wheels, or “volvelles,” descendants of the astrolabe.

In this introduction to astronomy and geography, the Moon lies embedded within a solid sphere carrying it around the Earth once a month. The solid sphere explains why the same side of the Moon always faces the Earth.

To provide entertainment at a dinner held by the Grand Duke of Tuscany, Galileo debated the Aristotelian physicist Lodovico delle Columbe on the topic of floating bodies. Galileo employed Archimedes’ mathematical analysis.

Planetary and stellar influences affect one’s physical temperament, so one must take steps not to catch the melancholic “influenza” of Saturn: “There’s some ill planet reigns: I must be patient till the heavens look With an aspect more favorable” (A Winter's Tale).

This is Kepler’s famous pretzel diagram, where he focused attention on the planet rather than the rotating solid sphere which carried the planet. In an Earth-centered system, the planet must follow some kind of similar pretzel path as it is carried along within a thick solid sphere.

Clip art with woodblocks: Estienne obtained a number of woodblocks from an obscure artist. To show anatomical detail, he cut little rectangles out of the art woodblocks and substituted his own diagrammatic drawings.

In Natural Magick, della Porta described an optical tube he designed to make far things appear as though they were near. The field of optics was often associated with magical tricks and illusions, and for that reason sometimes held suspect among non-mathematicians.

Della Porta explored various ideas for steam powered machines following the example of Hero of Alexandria. In antiquity, Hero fashioned marvelous automata using steam, air pressure, and hydraulics.

Not all versions of Euclid’s Elements were created equal. Clavius prepared this edition for his students at the Rome College (Collegio Romano). If these editions of Euclid were used in different courses, which course would you take?

This manuscript, a never-published treatise on sundials written in the author’s own hand, was lost in the 18th century and believed destroyed in a shipwreck. Baldi studied with one of Galileo’s teachers, Guidobaldo del Monte.

The ancient philosopher Hero described mechanics as the science of five simple machines: the lever, pulley, wheel, wedge and screw. These simple machines are combined in the complex inventions of Ramelli.

Kepler’s contributions reached far beyond the realm of astronomy, to meteorology, mathematics, geology, mineralogy and crystallography. Kepler published this 24-page pamphlet, a study of the snowflake, as a New Year’s greeting for a friend.

Nieremberg saw an unpublished manuscript of Hernandez. Many of his descriptions of plants and animals relied upon Hernandez and other sources from Mexico and Peru. In classification, Nieremberg retained Hernandez’ use of native Nahuatl names.

Robert Bellarmine was a prominent Jesuit theologian at the time of Galileo. Before several remarkable novas appeared, and 40 years before Galileo’s evidence of sunspots, Bellarmine had already come to believe on the basis of biblical authority that the heavens are not eternal but corruptible.

This work on astrology was written by the leader of a Paris circle of astronomers. That group extensively annotated the OU copy of Copernicus within a decade after it was printed.

Munster’s Cosmography was one of the most popular books of the 16th century. In addition to the map of the world, it includes separate maps for America, Africa, Asia and Europe. First published in 1540, at least 24 editions were published in the following century.

For two decades, Tycho and his assistants at Uraniborg produced thousands of astronomical observations of unprecedented quality. Tycho’s large-scale observing instruments, together with sophisticated new error correction techniques, increased observational precision by a factor of twenty.

Della Porta applied the “doctrine of signatures” to humans and animals, exploring how the shape of someone’s head, ears, nose or some other external feature might reveal that person’s true, inner nature by how closely it resembles a particular animal.

First book devoted to diseases of the eyes: In addition to professors in universities who published in Latin, health-care practitioners outside the universities, such as barber-surgeons and apothecaries, printed medical texts in the vernacular.

By far the best known 16th-century defender of Copernicus was Johann Kepler. In this work he demonstrated that vast empty regions lying between the planetary spheres, which were required by Copernicus, were not wasted space.

This work contains a survey of the constellations and a cosmological dialogue, Lo Spaccio de la Bestia Trionfante (The Expulsion of the Triumphant Beast, 1584). Bruno, a Dominican astrologer and philosopher, affirmed that the universe is infinite, having no center.

Lost plates for treatises on teeth, hearing and the kidneys, rediscovered: In the 1560’s, Eustachi, a professor of medicine in the Collegia della Sapienza in Rome, wrote several treatises devoted to particular organs of the body, including a pioneering work on the teeth.

Why physicians studied astronomy: Zodiac Man diagrams like this one reveal the hidden correspondences between the organs of the body (the microcosm) and the influences of the stars and planets that affect them (the microcosm).

Kepler’s major correspondence is gathered here in two rare volumes bound together. Bernegger, one of Kepler’s closest friends, also published Latin translations of Galileo’s Compass, Letter to the Grand Duchess Christina, and Dialogue on the Two Chief Systems of the World.

In De mundi aetherei (1588), Tycho reported that the comet of 1577 displayed no detectable parallax and thus moved, contrary to Aristotle, in the regions of the heavens beyond the Moon, passing through multiple celestial spheres. The ancient solid spheres melted.

Della Porta dedicated several books to Cesi. Cesi underwrote publication of this book on meteorology, which includes wide-ranging discussions of water, earthquakes and meteorites. The title page displays Cesi’s coat of arms.

In De revolutionibus, Copernicus placed the Sun in the center of the universe and set the Earth in annual motion around the Sun. This is the 3d edition, printed in 1617, the year after the Inquisition stimulated fresh interest in the work by placing it on the Index of Prohibited Books.

Scientific results were often reported in theological works, as in this first defense of Copernicanism in Spain. In his commentary on Job 9:6 (misnumbered 9:5), Zuniga summarized evidence for Copernicanism from the precession of the equinoxes.

This sun-centered cosmic section representes the first published defense of Copernicus in England, printed in a work of meteorology.

The illustrations in this cosmography show its indebtedness to the Sacrobosco tradition. Barozzi, a humanist scholar who lectured at the University of Padua, provided an updated introduction to observational astronomy, intended as a replacement for Sacrobosco and Peurbach.
