Circinus, Latin for compass, is one of the small southern (declination −50 to −60 degrees) constellations. It represents a tool used in drawing maps and as such should not be confused with Pyxis, a constellation associated with a ship's compass.

History

This constellation was designated in the 18th century, and first introduced by Nicolas Louis de Lacaille, whose unique fascination with secular science led to different names for these modern constellations. Since it is a creation of the 18th century, and was not visible to the cultures of the Mediterranean, there is no pre-18th century mythology associated with it.
