Jakob Bartsch

He was taught how to use the astrolabe by Sarcephalus (Christopher Hauptfleisch), a librarian in Breslau (Wrocław).

[1] In 1624 Bartsch published a book titled Usus astronomicus planisphaerii stellati containing star charts that depicted six new constellations introduced around 1613 by Petrus Plancius on a celestial globe published by Pieter van den Keere.

These six new constellations were Camelopardalis, Gallus, Jordanis, Monoceros (which he called Unicornu), Tigris and Vespa.

He also mentioned but did not depict Rhombus, a separate invention by Isaac Habrecht II.

[1] Bartsch died in Lauban in 1633. if there is anything that can bind the heavenly mind of man to this dusty exile of our earthy home and can reconcile us with our fate so that we can enjoy living – then it is verily the enjoyment of ... the mathematical sciences and astronomy.
