Argo, according to Greek mythology, was the ship on which the Argonauts embarked in order to go to Colchis and take the golden fleece. It took its name from the manufacturer Argos, son of Frixos and Chalkiopi. The construction of Argos was, according to the legend, at the request of the leader of the Jason campaign, by Argos and his brothers, Kitsiouro, Melana and Phrodis. The site of construction is reported by Pagasis, a secession port that was twenty steps away from Iolkos. The king of Iolkos, Pelias, commanded Argos not to steady the ship so that in the first storm he would sink. Argos, however, ignored the command of Pelias, building a ship in impeccable construction, while participating himself in the campaign. Beyond the most widespread version, according to which Argo was built by Frix’s son, its construction is also attributed to Argos, the hero of Argos or Argos from Thespies. A myth is still preserved, which is the name of Heracles, who chose the name to honor his favored person, Argos. Argo is described as the fastest and most solid boat of its time. In addition, it was extremely lightweight to allow it to be transported to the land by its crew. Some, more detailed, sources determine the length of the ship at 50 to 60 meters (long sailing). Governor of the ship was Tiftis. It is also reported that the goddess Athena (or Hera) placed on her bow a branch of the daisy Oak. This had divine qualities, he spoke with people and warned the Argonauts of the expected dangers. The capacity of the boat is an issue where there are significant differences between the various narratives. Some sources report places for sixty rowers, others for fifty (fifty) and others for less. At the end of the campaign, the Argonauts dedicated their ship to the Temple of Poseidon in the Isthmus. Based on myth, Argo is also associated with the end of Iason. In old age, Jason, after Medea’s suggestion, sat at the stern of Argos to rest. In this place he found tragic death because of the drop of a ship’s sail (catwalk), which was now marked by signs of time. Argo was later transferred to the sky and transformed into the homonym constellation. There was a tradition that part of the ship was transported to Rome and exhibited until 100 AD.
