As to what became of the ship Argo there are two stories. One is that Jason consecrated his vessel to Neptune on the isthmus of Corinth. Another is that Minerva translated it to the stars, where it became a constellation.
So ends the story of this earliest of recorded voyages, whose possible substratum of fact is overlaid deeply with fiction, and whose geography is similarly a strange mixture of fact and fancy. Yet though the voyage is at an end, our story is not. We have said that it was a tragedy, and the denouement of the tragedy remains to be given.
Pelias, who had sent Jason on this long voyage to escape the fate decreed for him by the oracle, took courage from his protracted absence, and put to death his father and mother and his infant brother. On learning of this murderous act Jason determined on revenge. But Pelias was too strong to be attacked openly, so the hero employed a strange stratagem, suggested by the cunning magician Medea. He and his companions halted at some distance from Iolcus, while Medea entered the town alone, pretending that she was a fugitive from the ill-treatment of Jason.
Here she was entertained by the daughters of Pelias, over whom she gained great influence by showing them certain magical wonders. In the end she selected an old ram from the king's flocks, cut him up and boiled him in a caldron with herbs of magic power. In the end the animal emerged from the caldron as a young and vigorous lamb. The enchantress now told her dupes that their old father could in the same way be made young again. Fully believing her, the daughters cut the old man to pieces in the same manner, and threw his limbs into the caldron, trusting to Medea to restore him to life as she had the ram.
Leaving them for the assumed purpose of invoking the moon, as a part of the ceremony, Medea ascended to the roof of the palace. Here she lighted a fire-signal to the waiting Argonauts, who instantly burst into and took possession of the town.
Having thus revenged himself, Jason yielded the crown of Iolcus to the son of Pelias, and withdrew with Medea to Corinth, where they resided together for ten years. And here the final act in the tragedy was played.
After these ten years of happy married life, during which several children were born, Jason ceased to love his wife, and fixed his affections on Glauce, the daughter of King Creon of Corinth. The king showed himself willing to give Jason his daughter in marriage, upon which the faithless hero divorced Medea, who was ordered to leave Corinth. He should have known better with whom he had to deal. The enchantress, indignant at such treatment, determined on revenge. Pretending to be reconciled to the coming marriage, she prepared a poisoned robe, which she sent as a wedding-present to the hapless Glauce. No sooner had the luckless bride put on this perilous gift than the robe burst into flames, and she was consumed; while her father, who sought to tear from her the fatal garment, met with the same fate.
Medea escaped by means of a chariot drawn by winged serpents, sent her by her grandfather Helios (the sun). As the story is told by Euripides, she killed her children before taking to flight, leaving their dead bodies to blast the sight of their horror-stricken father. The legend, however, tells a different tale. It says that she left them for safety before the altar in the temple of Juno; and that the Corinthians, furious at the death of their king, dragged the children from the altar and put them to death. As for the unhappy Jason, the story goes that he fell asleep under the ship Argo, which had been hauled ashore according to the custom of the ancients, and that a fragment of this ship fell upon and killed him.
The flight of Medea took her to Athens, where she found a protector and second husband in Ægeus, the ruler of that city, and father of Theseus, the great legendary hero of Athens.
