context_page_description: The Atlas Coelestis is a star atlas published posthumously in 1729, based on observations made by the First Astronomer Royal, John Flamsteed.
  The Atlas – the largest that ever had been published and the first comprehensive telescopic star catalogue and companion celestial atlas – contains 26 maps of the major constellations visible from Greenwich, with drawings made in the Rococo style by James Thornhill. It also presents two planispheres designed by Abraham Sharp.
context_section_description: The first stellar atlas based in telescopic observations, the Atlas Coelestis was published only ten years after the death of Flamsteed, by his widow, assisted by Joseph Crosthwait and Abraham Sharp. It was preceded by the opus "Stellarum inerrantium Catalogus Britannicus" (or simply "British Catalogue", published in 1725, with 2919 stars).
  One of Flamsteed's main motivations to produce the Atlas, was to correct the representation of the figures of the constellations, as made by Bayer in his "Uranometria" (1603). Bayer represented the figures viewed from behind (not from the front, as was done since the time of Ptolemy), which reversed the placement of stars and created unnecessary confusion.
  The publication enjoyed immediate success, becoming the standard reference for professional astronomers for nearly a century. Even so, three objections have been raised regarding it: the high price, great size (making it difficult to handle) and low artistic quality (many criticisms were made to the drawings by James Thornhill, particularly regarding the representation of Aquarius).
  This led Dr. John Bevis to try to improve the Atlas. In 1745, he produced the "Uranographia Britannica", with smaller dimensions, updated with observations and more artistic pictures. However, this atlas was never officially published and at the present, there are only 16 known copies.
