Argo Navis is the only one of the 48 constellations listed by the 2nd century astronomer Ptolemy that is no longer officially recognised as a constellation. In 1752, the French astronomer Nicolas Louis de Lacaille subdivided it into Carina (the keel, or the hull, of the ship), Puppis (the poop deck), and Vela (the sails).
