annotation | historical constellation not recognized today |
The constellation ship Argo , lat. Argo Navis , is no longer in use today. It was made up of today's constellations, the aft deck of the ship , the keel of the ship and the ship's sails . The ship Argo was introduced by Ptolemy , but was later split into the three upper ones by Nicolas Louis de Lacaille .
If this constellation were recognized, it would be larger than Hydra .
The ship's compass (pyxis) is located in an area that was previously considered the mast of the ship (malus) . Usually this constellation is not part of Argo Navis. The Bayer names for Pyxis also indicate this. Because the stars of Argo Navis were divided up one after the other. Carina received z. B. α, β and ε, Vela γ and δ, Puppis ζ, and so on, the stars Pyxis' do not fit in this order.
mythology
The Argo was the ship of Jason who was supposed to get the Golden Fleece . The constellation itself is not visible as a whole in Greece and could not be observed there in ancient times either. The stars Miaplacidus and Canopus form the ship's bottom . In ancient times the constellation was just south of the 32nd northern latitude to observe in its entire size. In the closest neighborhood these were: the African Mediterranean coast, old Palestine , Iraq (ancient Mesopotamia ), Iran (ancient Persia , above the Persian Gulf up to a maximum of 200 km).
In the Coelum Stellatum Christianum by Julius Schiller it was reinterpreted as Noah's Ark .
