Tycho Brahe prints: Portrait (6); Copenhagen (7); Hven (8); Gardens (9); Uraniborg (10); Architectural plan (11)

The island of Hven lies off the coast of Denmark. 

With income as feudal lord of Hven, Tycho Brahe built a castle of the stars, Uraniborg, in the center of the island. At Uraniborg, Tycho built an interdisciplinary research institute, welcoming scholars from across Europe to collaborate in the advancement of astronomy, alchemy and medicine. 

Medical research depended upon the tending of orchards and herb gardens. 

Alchemical work required furnaces, which at Uraniborg were tended night and day in round subterranean laboratories. 

Astronomy required precision instruments, housed on the nearby grounds and behind removable panels on the castle roof.

Aside from the portrait, these large framed prints are original leaves from one of the editions of Johann Blaeu, Le grand atlas; ou, Cosmographie blaviane (first published in Amsterdam, 1663).

Phases of Venus: Riccioli, New Almagest

Phases of Venus-Riccioli

The phases of Venus were an item of discussion in early modern Europe as scientists sought to determine whether it was evidence of the heliocentric system. Yet among the scientists it was anything but conclusive that this evidence proved the sun-centered universe. Learn more in this learning leaflet.

Six Cosmological Systems: Phases of Venus

Kircher-Cosmological Systems-Venus

It is often thought that Galileo's discovery of the phases of venus demonstrated the contested heliocentric model of the universe. However, such an understanding is overly simplistic of the early modern account of astronomy. Use this learning leaflet to learn more.

Elisabeth Hevelius: Observational Astronomer

Elisabeth Hevelius Learning Leaflet

How does the Sextant symbolize the person who worked on the famed Hevelius star catalog and star atlas throughout its production, from observation to publication? 

Elisabeth Hevelius, wife of Johann Hevelius, was an astronomer in her own right. They worked together in the observatory of their Gdansk home to measure angular widths and distances with a great sextant, which required two observers at a time. The Sextant was among the new constellations they proposed in Uranographia (1690), the most detailed and influential celestial atlas of the 17th century. The Uranographia contains 54 beautiful double page engraved plates of 73 constellations, and 2 oversized folding plates of planispheres.
