2 unusual facts about Johann Bayer


Chinese constellations

Ancient Chinese astronomers designated names to the visible stars systematically, roughly more than one thousand years before Johann Bayer did it in a similar way.

Pieter Dirkszoon Keyser

Johann Bayer copied the southern constellations from a Plancius/Hondius globe in his 1603 Uranometria star atlas, crediting charting to a "Petrus Theodori", but not acknowledging their earlier publication, and is therefore often mistakenly credited for introducing them.


Julius Schiller

Julius Schiller (c. 1580 – 1627) was a lawyer from Augsburg, Germany, who like his fellow citizen and colleague Johann Bayer published a star atlas in celestial cartography.
