Aries and Musca Borealis as depicted in Urania's Mirror, a set of constellation cards published in London c. 1825. Aries, one of the constellations of the zodiac, is located in the northern celestial hemisphere between Pisces and Taurus. Its name is Latin for ram, an animal it has represented since late Babylonian times. Aries is one of the 48 constellations described by the 2nd century astronomer Ptolemy; it remains one of the 88 modern constellations, while Musca Borealis does not.Illustration: Sidney Hall; restoration: Adam Cuerden
