Constellation Argo Navis

concept
Ἀργὼ Ναῦς
astronomy, voyage

The great southern constellation representing the ship Argo, in which Jason and the Argonauts sailed to Colchis to retrieve the Golden Fleece.

The Myth

The constellation Argo Navis commemorated the ship Argo, built by Argus with the guidance of Athena for Jason's quest to retrieve the Golden Fleece from Colchis. The ship was constructed from timber cut on Mount Pelion, and Athena fitted a sacred beam from the oak of Dodona into the prow, giving the vessel the power of prophecy. Jason gathered the greatest heroes of the age — Heracles, Orpheus, the Dioscuri Castor and Polydeuces, Atalanta, and dozens more. After securing the Fleece with Medea's help, the Argo was dedicated to Poseidon at the Isthmus of Corinth. Athena later placed the ship among the stars. The constellation was so vast that 18th-century astronomer Nicolas-Louis de Lacaille divided it into three smaller constellations: Carina (keel), Puppis (stern), and Vela (sails).

Fun Fact

Argo Navis was the largest constellation in Ptolemy's original 48 until it was broken into three pieces in 1763. The name lives on in the word "argonaut," which NASA used for its Argo program and which gives us the argonaut octopus — a creature named because its papery shell reminded naturalists of a tiny sailing ship navigating the open ocean.
