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.

Babylonian Constellation

In the place of the Greek Argo, the Babylonian uranology recognizes the constellations of the Harrow and the Asterism of Eridu.

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).
