Argo was constructed by the shipwrightArgus, and its crew were specially protected by the goddess Hera. The best source for the myth is the Argonautica by Apollonius Rhodius. According to a variety of sources of the legend, Argo was said to have been planned or constructed with the help of Athena. According to other legends she contained in her prow a magical piece of timber from the sacred forest of Dodona, which could speak and render prophecies. After the successful journey, Argo was consecrated to Poseidon in the Isthmus of Corinth. She was then translated into the sky and turned into the constellation of Argo Navis.
Several authors of antiquity (Apollonius Rhodius, Pliny,Philostephanus) discussed the hypothetical shape of the ship. Generally she was imagined like a Greek warship, a galley, and authors hypothesized that she was the first ship of this type that had gone out on a high-sea voyage.
