history
The dove is not one of the 48 classic constellations of antiquity .
It is one of three newer constellations introduced by the Dutch astronomer and theologian Petrus Plancius in the 17th century .
It is related to the neighboring constellations aft deck of the ship (Puppis), keel of the ship (Carina) and sails (Vela), which at that time formed the extensive constellation of the ship Argo (Argo Navis).
