Argo Navis

Argo Navis was a large southern constellation representing the ship used by Jason and the Argonauts. It is the only one of Ptolemy's list of 48 constellations which is no longer officially recognised as a constellation, having been broken up into Carina (the keel of the ship), Puppis (the poop), Vela (the sails), and Pyxis (the compass).
