Custos Messium, the Harvest Keeper, was a constellation invented in Early Modern Time by the French astronomer Joseph Jérôme de Lalande (1732–1807) who might have punned with the name of his compatriot Charles Messier. Some European astronomers copied and translated it, though. The constellation became obsolete in the depolitisation of the IAU-sky and WGSN only resembles the Keeper, Custos.
