Striking celestial map from an early edition of Andreas Cellarius' Harmonia Macrocosmica.
The map illustrates the various magnitude of various celestial bodies and stars.
The Harmonia Macrocosmica of Andreas Celarius, is widely regarded as the most beautiful and finely executed celestial atlas ever published. The atlas appeared in two early editions of 1660 and 1661, and was also intended as part of Jansson's, Atlas Maior. Schenk & Valk re-issued the atlas in 1708, using the original Cellarius plates, without alteration, except for the addition of their names in the title cartouche.
Andreas Cellarius was born in 1596 in Neuhausen and educated in Heidelberg. He emigrated to Holland in the early 17th century, and in 1637 moved to Hoorn, where he became the rector of the Latin School. Cellarius' best-known work is his Harmonia Macrocosmica, first issued in 1660 by Jan Jansson, as a supplement to Jansson's Atlas Novus. The work consists of a series of Celestial Charts begun by Cellarius in 1647 and intended as part of a two-volume treatise on cosmography, which was never issued.
