Uranometria





Uranometria
The first star atlas to cover the entire sky, published by Johann Bayer in 1603 and based on positions taken from Tycho Brahe's catalogue. It contained 51 charts, one for each of Ptolemy 48 constellations, one for the southernmost skies which were unknown to Ptolemy (introducing 12 new southern constellations defined by the Dutch navigators Keyser and de Houtmann), and two planispheres. Uranometria also introduced the Bayer designations, which are still used today.
