Before he could render suitable thanks, the goddess had disappeared, and Jason continued his journey, full of courage and confident of success. Soon he came to his native city, where he found a great crowd of people assembled at the temple, for Pelias, the king, was offering on that day special sacrifices, and a public festival had been proclaimed throughout the city. Jason joined in the crowds that were hurrying to the temple, and stood quite near his uncle, while the king, unconscious of his presence, was performing the sacrifices. When the ceremony was over, Pelias glanced around at the assembled company, and started back pale with terror when he saw Jason; for although he did not recognize his nephew, he had been warned by an oracle to beware of a youth who would appear before him wearing only one sandal. Trembling, but striving to hide his fear, Pelias spoke to the stranger and asked him his name. Then Jason confronted his uncle boldly, declared his own parentage, and demanded that the usurper should at once resign his throne and restore old Æson to his rightful place in the kingdom.
Pelias did not dare openly to defy this fearless youth, but neither did he intend to give up his power and wealth; so being a crafty man he sought to beguile Jason with soft words, and promised to send at once for the absent king and queen. He urged his nephew to remain meanwhile at the court, and invited him to join the royal household that evening in a splendid banquet. Jason needed no persuasion to eat, drink, and be merry; and as the wily Pelias plied him with rich viands and the choicest wine, his heart warmed toward his uncle, and he felt less eager to carry out his long-cherished vengeance. During the feast the bards sang of brave deeds done by heroes, and one old musician told of the famous golden fleece that many had sought to take by stealth; but of those who went on the quest, no one ever came back to tell why he had failed.
Jason listened eagerly while the old singer told how the famous fleece once belonged to a ram that the friendly Neptune sent to Phryxus and Helle to enable them to escape from the persecutions of their stepmother Ino. This was the same Ino who cared so tenderly for the infant Bacchus; but to her stepchildren she was very cruel. Their own mother Nephele had been sent away by King Athamas because he had wearied of her, and wished to marry Ino; and when the banished mother learned how neglected and ill-treated her children were, she begged Neptune to help them. So the sea-god sent a golden-fleeced ram, which Phryxus and Helle mounted and thus escaped from their cruel stepmother. Only Phryxus reached the land of Colchis, however; for when the ram flew over the sea, Helle grew frightened at the sight of the waves tossing so far beneath her, and suddenly lost her hold on the golden fleece. Her brother reached out to clutch her as she slid from the ram's back, but it was too late, and the unfortunate maiden fell into that part of the sea that is since known as the Hellespont. Phryxus reached Colchis safely, and here he sacrificed the ram to Neptune, and hung its golden fleece on a tree under which he placed a dragon to guard it night and day.
