Argo
Argo Navis (short: Argo) is one of the constellations of the Almagest star catalogue (137 CE) that became standardized by common usage of several cultures in the subsequent centuries. In the Early Modern Era, the constellation was changed and finally included in the set of constellations, globally defined by the IAU over the course of the 1920s.
History of Argo
There is no Babylonian predecessor at the place of this Greek constellation. In the place of the Greek Argo, the Babylonian uranology recognizes the constellations of the Harrow and the Asterism of Eridu.
Yet, the Babylonian uranology does contain a constellation of a ship or rather a boat but this is at the opposite site of the sky, frequently identified with the stars in the modern constellations Sgr, CrA and Cap (or only CrA). Some scholars think that The Ship (now called Argo) in the Greek culture is halved and sails backwards through the sky because of hypothetical roots in the Epic of Gilgamesh. However, this scholarly suggestions lacks evidence.
Aratus
Close to the great Dog’s tail is Argo towed stern first. Its course is not that of a ship proceeding on its normal business, but its movement is backward-turned, like that of real [345] ships when the sailors have already turned the stern about on entering harbour: all the crew quickly back water, and the ship surging astern makes fast to the land. So this Argo of Jason is towed stern first. Dark and starless from the prow as far as the actual mast she goes, but the rest is all bright. [351] The steering-oar is detached and set fast under the Dog’s hind legs as it runs ahead. (Kidd 1997)

Some have said this ship was called Argo in Greek on account of her speed, others because Argus was her inventor. Many have said she was the first ship on the sea, and for this reason especially was pictured in the stars. Pindar says she was built in the town of Magnesia called Demetrias — Callimachus in that district near the temple of Actian Apollo which the Argonauts are thought to have founded on their departure. The place is called Pagasae, in Greek pagasai, because the Argo was first fitted together there. Homer says that this same place was in the district of Thessaly. Aeschylus and some others say that in the same place a speaking beam was added by Minerva. The entire form of the ship does not appear in the stars; it is divided from stern to mast, signifying that men should not be in despair when their ships are wrecked. (Mary Ward 1960)

Splitting Argo up into three constellations
In 1755, Nicolas Louis de Lacaille divided Argo into the three modern constellations that occupy much of the same area: Carina (the keel), Puppis (the poop deck or stern), and Vela (the sails).
In his 1768 Coelum Australe Stelliferum, Lacaille divided the more than 160 stars in the constellation into the regions Argûs in carina (Carina, the keel), Argûs in puppi (Puppis, the stern), and Argûs in velis (Vela, the sails).
