This celebrated hero was the son of Alcemede, by Æson; the education of the youthful Jason, whose right of succession to the throne of Iolchos had been wrested from him by Pelias, was entrusted to the care of the centaur Chiron, and he was removed from the presence of the usurper of the kingdom of Iolchos, because the latter had been informed by an oracle that one of the descendants of Æolus, (from whom Jason had come) would dethrone him. After he had distinguished himself by the most rapid success in every branch of science, Jason left the country, and by the advice of his preceptor, went to consult the oracle. He was ordered to
go to Iolchos, his native country, covered with the spoils of a leopard, and dressed in the garments of a Magnesian. In his journey he was stopped by the inundation of a river, over which, however, he was carried by Juno, in the character of an old woman. In crossing the stream, he lost one of his sandals, and on his arrival at Iolchos, the singularity of his dress, and the fairness of his complexion, attracted the notice of the people, and drew a crowd round him in the market place. Pelias came to see him with the others, and, as he had been warned by the oracle, to beware of a man who should appear at Iolchos with one foot bare, and the other shod, the appearance of Jason, who as we have seen, had lost one of his sandals, alarmed him, and his terrors were soon after augmented, as Jason, accompanied by his friends repaired to the palace of Pelias, and demanded the kingdom of which he had been unjustly deprived. The boldness of Jason intimidated Pelias; he was unwilling to abdicate the crown, yet he feared the resentment of his adversary.
As Jason was young and desirous of glory, Pelias reminded him that their common relation, Phryxus, had been inhumanly murdered by Æetes, king of Colchis, in order to obtain possession of the golden fleece which belonged to the murdered man; observing, that, the deed merited punishment, and was one which would produce a crown of glory to him who should inflict it; adding, that if Jason, were to undertake it, he would resign his own crown and kingdom to him, immediately on his return. Burning with the desire of
military fame, Jason readily undertook an expedition which seemed to promise so much glory. The expedition was bruited about all Greece, and the young and ardent of the nation were called upon to join him in the glory and the danger.
They set sail in a ship called Argo and after a series of adventures arrived at Colchis. Alarmed at an invasion which appeared so formidable, Æetes promised to restore the golden fleece for the possession of which he had slain Phryxus, provided the invaders consented to the conditions he should propose, and which were as follows: Jason was to tame bulls whose breath were fierce flames, with feet and horns of brass, and to plough with them, when subdued, a field sacred to Mars. He was then to sow in the ground the teeth of a serpent, from which armed men would spring up, whose rage would be directed against him who should be daring enough to plough the field; and as a conclusion to his arduous tasks, he was to kill a frightful dragon which remained ever on the watch at the tree where the golden fleece was suspended. All were in fear for the fate of the Argonauts, but Juno watched over their safety, and extricated them from their difficulties. Medea, the king's daughter, fell in love with Jason, and in an interview with her lover in the temple of Hecate, in which they swore a mutual fidelity, and bound themselves by the most solemn oaths, she pledged herself to deliver her lover from all his dangers. Her knowledge of herbs, enchantments and incantations, was uncommon, and he received from her whatever instruments and herbs could protect him against the coming dangers.
"She then retires to Hecate's shrine, that stood
Far in the covert of a shady wood:
She finds the fury of her flames assauged,
But, seeing Jason there, again they raged.
