Cancer Constellation, Zodiac, 1729

Cancer is one of the constellations of the zodiac. It is one of the 48 constellations described by the 2nd century astronomer Ptolemy, and remains one of the 88 modern constellations defined by the International Astronomical Union. Constellations directly bordering Cancer are Lynx, Gemini, Canis Minor, Hydra, Leo and Leo Minor. Cancer is the fourth astrological sign in the Zodiac, which is associated with the constellation Cancer. It spans the 90-120th degree of the zodiac, between 90 and 125.25 degree of celestial longitude, which the Sun transits this area on average between June 22 to July 22 each year. 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. One of his main motivations to produce the Atlas, was to correct the representation of the figures of the constellations, as made by Bayer's, 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.
