Title: Hand-painted illustration from the autograph album of Johann Jakob Frisch
Format: photograph: negative

Description: Frisch was a nephew of Johannes Kepler. The album was kept by Frisch while a law student at the University of Tubingen (from 1624 to 1631), where Kepler himself also had studied. Autograph entries are typicaly in Latin, and range from a few lines of verse or prose to elaborate miniature illustrations, comic and serious. Kepler’s autograph is included in the book within a Latin inscription dated 1625.

Title: Kepler - preliminary diagram relating to the orbits of Saturn and Jupiter, from Mysterium cosmographicum
Format: photograph: negative
Date: 1596
Description: With this first diagram, Kepler thought that he had discovered the key to unlocking a geometrical secret about the creation of the universe. His education at the university of Tubingen with Michael Maestlin had already convinced him of the truth of the Copernican system, and starting in 1595, he was trying to explain the relationship among the distances of the planets from the sun and the length of their revolutionaround the sun. The diagram came to Kepler as a revelation. As he was explaining some astrological matters to his students, he drew triangles inscribed in the same circle - or nearly triangles since the end of one made up the beginning of the next one. The crossing points of these triangles formed another circle, half the size of the first one. That proportion, he realized, was the same as the proportion between the orbits of Saturn and Jupiter. The importance of the Mysterium Cosmographicum doesn’t lie in its scientific value, but more in Kepler’s processes since he didn’t just present the result of his researches (such as the world system inscribed in the five regular bodies, which he considered at that time as an real achievement in favor of the Copernican system), but he also shows to the reader all his beginnings and errors, as it is the case with that diagram.

Title: William Whiston - fig.4 for A New Theory of the Earth (London, 5th edn., 1737)
Format: photograph: negative
Date: 1737
Description: The path of the Earth through the Atmosphere and Tail of a Comet. Newton and Edmond Halley had worked hard to demonstrate that comets were predictable, periodic bodies which therefore could not be used to prognosticate divine interventions in the natural order. Yet they also suggested that comets deposited aethers to revitalize a spiritually depleted Earth. Whiston liked this mixture of close geometrical analysis with divine mechanism, and extended the discussion. He argued that comets had been responsible for key moments in the Earth’s natural and biblical history - for instance, it was a great comet that had caused the Deluge. He even equated comets with Hell: as they moved in their highly eccentric orbits, they alternated between the “Darkness of Torment” and the “ungodly Smoak of Fire.” For Whiston, comets thus became “the place of Punishment for wicked Men after the general Resurrection.”
