Argus was the builder and most likely the designer of the Argonauts ship "The Argo." He named the ship after himself. By building the ship he automatically became part of the crew itself. Later during the quest for the Golden Fleece Jason would run into four or five brothers one of whom was also Argus. Argus was one of the Argonauts that did make it through the entire voyage.
Polybus and Argia
"Argus, son of Polybus and Argia; some say son of Danaus. He was an Argive, waring a black-haired bull’s hide. He was the builder of the ship Argo."
- Hyginus, Fabulae, 14
