Jason was the heroic leader of the Argonauts, a team of heroes who journeyed from Greece to distant Colchis in quest of the Golden Fleece.
Jason was the son of the lawful king of Iolcus, but his uncle Pelias had usurped the throne. Pelias lived in constant fear of losing what he had taken so unjustly. He kept Jason's father a prisoner and would certainly have murdered Jason at birth. But Jason's mother deceived Pelias by mourning as if Jason had died. Meanwhile the infant was bundled off to the wilderness cave of Chiron the Centaur. Chiron tutored Jason in the lore of plants, the hunt and the civilized arts.
When Jason came of age he set out like a proper hero to claim his rightful throne. Unbeknownst, he was to play his part in a plan hatched on lofty Mount Olympus, where Hera, wife of mighty Zeus himself, nursed a rage against King Pelias. For Jason's uncle, the usurper king, had honored all the gods but Hera. Rashly had he begrudged the Queen of Heaven her due.
Hera's plan was fraught with danger; it would require a true hero. To test Jason's mettle, she contrived it that he came to a raging torrent on his way to Iolcus. And on the bank was a withered old woman. Would Jason go about his business impatiently, or would he give way to her request to be ferried across the stream? Jason did not think twice. Taking the crone on his back, he set off into the current. And halfway across he began to stagger under her unexpected weight. For the old woman was none other than Hera in disguise. Some say that she revealed herself to Jason on the far shore and promised her aid in his quest. Others claim that Jason never learned of the divine service he had performed.
Jason lost a sandal in the swift-moving stream. This would prove significant in Hera's revenge. For an oracle had warned King Pelias, "Beware a stranger who wears but a single sandal."
When Jason arrived in Iolcus, he asserted his claim to the throne. His uncle Pelias had no intention of giving it up, particularly to a one-shoed stranger. Under the mask of hospitality, he invited Jason to a banquet. And during the course of the meal, he engaged him in conversation.
"You say you've got what it takes to rule a kingdom," said Pelias. "May I take it that you're fit to deal with the thorny problems that arise? For example, how would you go about getting rid of someone who was giving you difficulties?"
Jason considered for a moment, eager to show a kingly knack for problem solving. "Send him after the Golden Fleece?" he suggested.
"Not a bad idea," responded Pelias. "It's just the sort of quest that any hero worth his salt would leap at. Why, if he succeeded he'd be remembered down through the ages. Tell you what, why don't you go?"
And so it came to pass that word went out the length and breadth of Greece that Jason was looking for shipmates to embark upon a perilous but highly glamorous adventure. And despite that Pelias had been attracted to the idea precisely because of the miniscule chances of anyone surviving to lay eyes upon the Fleece let alone get past the guarding dragon and return with the prize, large numbers of heroes were ready to run the risk. Among them were Heracles and the heroine Atalanta. So Jason arranged to have a ship constructed by the worthy shipwright Argus, who in a fit of vanity named the vessel more or less after himself, calling her the "Argo".
Argus had divine sponsorship in his task. The goddess Hera, who had it in for Pelias, enlisted the aid of her fellow goddess Athena. This patroness of crafts secured a prow for the vessel from timber hewn at the sacred grove of almighty Zeus. This prow had the magical property of speaking - and prophesying - in a human voice.
And so one bright autumn morning the Argo set out to sea, her benches crewed by lusty ranks of heroic rowers. And true to Pelias's fondest aspirations, it wasn't long before big troubles assailed the company. After stopping for better than a fortnight on an island populated exclusively by women, they put in at Salmydessus.
The king welcomed them but was in no mood for festive entertainment. Because he'd offended the gods, he'd been set upon by woman-headed, bird-bodied, razor-clawed scourges known as Harpies. These Harpies were possessed of reprehensible table manners. Every evening at dinnertime, they dropped by to defecate upon the king's repast and hung around making such a racket that he wouldn't have been able to eat had he the stomach for it.
As a result, King Phineus grew thinner by the hour. Fortunately two of Jason's crew were direct descendants of the North Wind, which gave them the power to fly. And they kindly chased the Harpies so far away that the king was never bothered again. In thankfulness, he informed the Argonauts of a danger just ahead on the route to the Golden Fleece - namely two rocks called the Symplegades, which had the disconcerting habit of crashing together upon any ship that passed between them.
Phineus suggested that it might be best not to experience the effect of these Clashing Rocks firsthand. And he even suggested a mechanism by which this might be avoided. If someone or something could be induced to pass between the crags first, causing them to clash together, the Argo could follow quickly behind, passing through safely before the Symplegades were ready to snap shut again. By means of this device, Jason caused the rocks to spring together prematurely. The Argo was able to pass between them relatively unscathed. Only her very stern was nipped and splintered.
Once arrived in Colchis, Jason had to face a daunting series of challenges before he could even get to the grove where the Golden Fleece was hanging. And it was another irascible king who handed out the assignments. King Aeetes of Colchis was ruler of this barbarian kingdom on the far edge of the heroic world. He and his people were not kindly disposed toward strangers. On an earlier occasion, however, he had extended a gracious hand to a visitor from Jason's home town. This may have been due to the newcomer's unorthodox mode of transportation. For he arrived on the back of a golden-fleeced flying ram.
The stranger's name was Phrixus, and he and his sister had been on the point of being sacrificed when the ram carried them off. The sister, whose name was Helle, had fallen from the ram's back into the narrow passage of water that came to be called the Hellespont in her memory. But Phrixus arrived safely in Colchis, where he sacrificed the ram to the gods and hung its fleece in a grove. Aeetes gave him the hand of one of his daughters in marriage.
King Aeetes had taken a disliking to Jason on sight. He had no particular fondness for handsome young strangers who came traipsing into his kingdom on glorious quests featuring the trampling of his sacred grove and the carrying off of his personal property. For King Aeetes considered the Golden Fleece to be his own, and he was in the midst of telling Jason just what he could do with his precious quest when he was suddenly reminded of the obligations of hospitality by another of his daughters named Medea.
Medea was motivated by more than good manners. For the goddess Hera had been looking out for Jason's interests, and she had succeeded in persuading her fellow goddess Aphrodite to intervene on Jason's behalf. It was no problem at all for the Goddess of Love to arrange that Medea be stricken with passion for Jason the moment she first saw him. And it was a good thing for Jason that this was so. For not only was he spared a kingly tongue-lashing and a quick trip to the frontier, but Medea quietly offered to help him in his latest predicament. For once her father had calmed down, he had waxed suspiciously reasonable.
Of course Jason could have the Fleece and anything else he required in furtherance of his quest - Aeetes couldn't imagine what had possessed him to be so uncooperative. All he required of Jason as a simple token of good faith was the merest of farmyard chores. There were two bulls standing in the adjacent pasture. If Jason would be so kind as to harness them, plow the field, sow it and reap the harvest in a single day, King Aeëtes would be much obliged - and only too happy to turn over the Golden Fleece.
Oh, and there was one trifling detail of which Jason should be aware. These bulls were a bit unusual in that their feet were made of brass sharp enough to rip open a man from gullet to gizzard. And then of course there was the matter of their bad breath. In point of fact, they breathed flames.
Along about this juncture Jason thought he heard his mommy, Queen Polymede, calling. But then, as noted, Medea took him gently aside and suggested that she might be of aid. Quite conveniently for Jason, Medea was a famous sorceress, magic potions being her stock in trade. She slipped Jason a salve which, when smeared on his body, made him proof against fire and brazen hooves.
And so it was that Jason boldly approached the bulls and brooked no bullish insolence. Disregarding the flames that played merrily about his shoulders and steering clear of the hooves, he forced the creatures into harness and set about plowing the field. Nor was the subsequent sowing any great chore for the now-heartened hero. Gaily strewing seed about like a nymph flinging flowers in springtime, he did not stop to note the unusual nature of the seed.
Aeetes, it turns out, had got his hands on some dragon's teeth with unique agricultural properties. As soon as these were lodged in the soil they began to sprout, which was all to the good from the point of view of Jason accomplishing his task by nightfall, but bad from that of the harvest. For each seed germinated into a fully-armed warrior, who popped up from the ground and joined the throng now menacing poor Jason. Here indeed was a prickly harvest.
Aeetes, meanwhile, was standing off to the side of the field chuckling quietly to himself at Jason's discomfiture and pending dismemberment in sorely mismatched combat. It irked the king somewhat to see his daughter slink across the furrows to Jason's side. But then Aeetes didn't think too much of it at the time. Having proven herself polite to a fault, maybe Medea was just saying a brief and proper farewell.
In actuality, she was once more engaged in saving the young hero's posterior. This time there was no traffic in magic embrocations. Medea merely gave Jason a tip in basic psychology. Jason, who it was quite clear by now lacked the heroic wherewithal to make the grade on his own, at least had the sense to recognize good advice. Employing the simple device suggested by Medea, he brought the harvest in on deadline with a minimum of personal effort. He simply threw something at one of the men. The man, in turn, thought his neighbor had done it. And in short order all the seed men had turned on one another with their swords until not one was left standing.
Aeetes had no choice but to make as though he'd give the Fleece to Jason, but he still had no intention of doing so. He now committed the tactical error of divulging this fact to his daughter. And Medea, still entranced by the Goddess of Love, confided in turn in Jason. Furthermore, she offered to lead him under cover of darkness to the temple grove where the Fleece was displayed, nailed to a tree and guarded by a dragon.
And so at midnight they crept into the sacred precinct of Ares, god of war. Jason, ever the hothead, whipped out his sword, but Medea wisely restrained his impetuosity. Instead, she used more subtle means to subvert the monster's vigilance. Together they made off with the Fleece and escaped to the Argo. Setting sail at once, they eluded pursuit.
Thus Jason succeeded in his heroic challenge. And once returned to Greece, he abandoned Medea for another princess. For though Jason had sworn to love and honor Medea for the service she had done him, he proved as fickle in this regard as he'd been unfit for single-handed questing.
