Jason. Jason, the son of Æson, king of Thessaly, by Alcimede, was an infant when his father died, and his uncle Pelias took upon himself the direction of the government. Pelias did not resign the crown when Jason, coming of age, laid his claims to it; but, with the hope of seeing him destroyed, advised him to go to Colchis, and gain the golden fleece. […] Jason chose for his companions about fifty of the most noble and famous in Greece. […] In a little time Jason abandoned her for Creusa, daughter to Creon, king of Corinth; but to revenge his perfidy, Medea not only murdered in his sight the two children which she had borne him, but also enclosed fire in a little box, and sent it to Creusa.
