Quadrans Muralis

Map of the obsolete constellation Quadrans Muralis

Quadrans Muralis (Latin for mural quadrant) was a constellation created by Jérôme Lalande in 1795. It was located between the constellations of Boötes and Draco, near the tail of Ursa Major. It is no longer in use, but the Quadrantid meteor shower is named after it.

Quadrans Muralis can be seen at the top left of this 1825 star chart from Urania's Mirror.
