The mythical single-horned beast, the unicorn, is represented by this constellation which was unknown to the ancient Greeks. Monoceros was first depicted in 1612 under the name Monoceros Unicornis on a globe by the Dutch theologian and cartographer Petrus Plancius (this was the same globe on which Camelopardalis, another of his inventions, first appeared). In 1624 the German astronomer Jacob Bartsch depicted it under the name Unicornu (sic) on a star chart in his book Usus Astronomicus Planispha
