- Argo Navis
Argo Navis (or simply Argo) was a large southern
constellationrepresenting the " Argo", the ship used by Jasonand the Argonautsin Greek mythology. The abbreviation was "Arg" and the genitive was "Argūs Navis".
It is the only one of
Ptolemy's list of 48 constellations that is no longer officially recognised as a constellation. French astronomer Nicolas Louis de Lacaillein 1752subdivided Argo Navis into Carina (the keel of the ship), Puppis(the Poop deck), and Vela (the sails). Were this still considered to be a single constellation, it would be the largest of all, being larger than Hydra.
When Argo Navis was split, its
Bayer designations were also split. Carina has the α, β and ε, Vela has γ and δ, Puppis has ζ, and so on.
Pyxisoccupies an area which in antiquity was considered part of Argo's mast. However, Pyxis is not now (usually) considered part of Argo Navis, and in particular its Bayer designations are separate from those of Carina, Puppis and Vela.
