Title: William Whiston - title page to A New Theory of the Earth, 5th edition (London, 1737)
Format: photograph: negative
Date: 1737
Description: Whiston succeeded Isaac Newton as third Lucasian Professor of Mathematics at Cambridge University in 1701. An early apostle of Newtonian philosophy, he entered the debate on Biblical chronology with his book, “A New Theory of the Earth” (1696), which sought to refute the widely read work of Thomas Burnet, “The Sacred Theory of the Earth.” Although both Whiston and Burnet were to some degree skeptical of Biblical (or Mosaic) accounts of creation, Whiston proposed a theory that the flood was caused by the impact of a comet.

Title: Canis Minor
Format: print: engraving
Date: 1603
Description: From Johann Bayer’s “Uranometria” (1603), the first ‘true’ star-atlas. This and other copper-engraved images from the book demonstrate a notable feature of this atlas: the sheer beauty of the plates. Alexander Mair, the artist, clearly found some inspiration in the De Gheyn engravings in the Aratea published by Hugo Grotius in 1600, but most of Bayer’s constellation figures have no known prototype. Significantly, each plate has a carefully engraved grid, so that star positions can be read off to fractions of a degree. These positions were taken, not from Ptolemy’s catalog, but from the catalog of Tycho Brahe, which had circulated in manuscript in the 1590s, yet not printed until 1602. Another important feature of the atlas was the introduction of a new system of stellar nomenclature, Bayer assigning Greek letters to the brighter stars, generally in the order of magnitude.

Title: Oculus Enoch et Eliae, sive Radius Sideromysticus pars Prima
Format: photograph: negative
Date: 1645
Description: Anton Maria Schyrleus (1597-1660) was a Capuchin priest and professor, who worked in Bohemia, Trier and Ravenna. His astronomical work was completed in the low countries in the 1640s, and resulted in this rather unusual work -- a richly illustrated example of baroque natural philosophy. The Oculus might be considered a mystical work, reflecting the harmonies of an earth-centered, Tychonic cosmos in scriptural terms. The illustrations give a vivid impression of its combination of technical astronomy and mechanics with rich symbolism.
