Vintage illustration astronomy and antique celestial star chart image featuring the stars of three constellations, Monoceros (Greek for Unicorn), Canis Minor and Atelier Typographique. Monoceros (Greek for Unicorn) is a faint constellation on the celestial equator. Its creation is attributed to the 17th-century Dutch cartographer Petrus Plancius. It is bordered by Orion to the west, Gemini to the north, Canis Major to the south and Hydra to the east. Other bordering constellations include Canis Minor, Lepus and Puppis. Canis Minor is a small constellation. It was included in the 2nd century astronomer Ptolemy's 48 constellations, and is still included among the 88 modern constellations. Its name is Latin for "smaller dog" in contrast to Canis Major, the larger dog, and it is commonly represented as one of the dogs following the constellation of Orion the hunter. Atelier Typographique is depicted by the artist's workstation.
