[Ophiuchus (Serpentarius)] [Stars Heightened in Gold].

Augsburg: 1603. "Striking full color example of Bayer's celestial chart of Ophiucus (Serpentarius), with the stars heightened in gold.
Ophiuchus is one of the 48 constellations named by Claudius Ptolemy, named for the Greek word "Serpent Bearer." Pphiuchusis shown grasping the sonstellation Serpens. Bayer's Uranometria, is one of the most important celestial atlases of the 17th Century and the Forerunner of all star atlases which contained 51 star charts, of which 48 were Ptolomeic constellations.
Each plate has a carefully engraved grid, so that star positions can be read off to fractions of a degree. These positions were taken from the catalogue of Tycho Brahe. Brahe's catalogue had circulated in manuscript in the 1590s, but was not published until 1602.
Another important feature of the Bayer's atlas was the introduction of a new system of stellar nomenclature. Bayer assigned Greek letters to the brighter stars, generally in the order of magnitude, so that the bright star in the Bull's eye became Alpha Tauri (and the brightest star in the Centaur became our familiar Alpha Centauri). These letters were placed on the charts themselves, and also in a table that accompanied each chart. Bayer's charts are rarely offered seperately on the market." Very Good. Minor toning, else bright and clean. 15x11" Item #9521
