Celestial cartography

The word "uranography" derived from the Greek "ουρανογραφια" (Koine Greek ουρανος "sky, heaven" + γραφειν "to write") through the Latin "uranographia". In Renaissance times, Uranographia was used as the book title of various celestial atlases. During the 19th century, "uranography" was defined as the "description of the heavens". Elijah H. Burritt re-defined it as the "geography of the heavens". The German word for uranography is "Uranographie", the French is "uranographie" and the Italian is "uranografia". ==Astrometry==

Astrometry, the science of spherical astronomy, is concerned with precise measurements of the location of celestial bodies in the celestial sphere and their kinematics relative to a reference frame on the celestial sphere. In principle, astrometry can involve such measurements of planets, stars, black holes and galaxies to any celestial body. Throughout human history, astrometry played a significant role in shaping our understanding of the structure of the visible sky, which accompanies the location of bodies in it, hence making it a fundamental tool to celestial cartography. ==Star catalogues==

A determining fact source for drawing star charts is naturally a star table. This is apparent when comparing the imaginative "star maps" of Poeticon Astronomicon – illustrations beside a narrative text from the antiquity – to the star maps of Johann Bayer, based on precise star-position measurements from the Rudolphine Tables by Tycho Brahe. Important historical star tables • c:AD 150, Almagest – contains the last known star table from antiquity, prepared by Ptolemy, 1,028 stars. • c.964, Book of the Fixed Stars, Arabic version of the Almagest by al-Sufi. • 1627, Rudolphine Tables – contains the first West Enlightenment star table, based on measurements of Tycho Brahe, 1,005 stars. • 1690, Prodromus Astronomiae – by Johannes Hevelius for his Firmamentum Sobiescanum, 1,564 stars. • 1729, Britannic Catalogue – by John Flamsteed for his Atlas Coelestis, position of more than 3,000 stars by accuracy of 10". • 1903, Bonner Durchmusterung – by Friedrich Wilhelm Argelander and collaborators, circa 460,000 stars. ==Star atlases==

Naked-eye • 15th century BC – The ceiling of the tomb TT71 for the Egyptian architect and minister Senenmut, who served Queen Hatshepsut, is adorned with a large and extensive star chart. • 1 CE ? Poeticon astronomicon, allegedly by Gaius Julius Hyginus • 1092 – Xin Yi Xiang Fa Yao (新儀 象法要), by Su Song, a horological treatise which had the earliest existent star maps in printed form. Su Song's star maps also featured the corrected position of the pole star which had been deciphered due to the efforts of astronomical observations by Su's peer, the polymath scientist Shen Kuo. • 1515 – First European printed star charts published in Nuremberg, Germany, engraved by Albrecht Dürer. • 1603 – Uranometria, by Johann Bayer, the first western modern star map based on Tycho Brahe's and Johannes Kepler's Tabulae Rudolphinae • 1627 – Julius Schiller published the star atlas Coelum Stellatum Christianum, which replaced pagan constellations with biblical and early Christian figures. • 1660 – Jan Janssonius' 11th volume of Atlas Major (not to be confused with the similarly named and scoped Atlas Maior) featured the Harmonia Macrocosmica by Andreas Cellarius • 1693 – Firmamentum Sobiescanum sive Uranometria, by Johannes Hevelius, a star map updated with many new star positions based on Hevelius's Prodromus Astronomiae (1690) – 1564 stars.
