Bk VII:159-178 Jason asks Medea to lengthen Aeson's life.
The elderly Haemonian mothers and fathers bring offerings to mark their sons' return, and melt incense heaped in the flames. The sacrifice, with gilded horns, that they have dedicated, is led in and killed. But Aeson is absent from the rejoicing, now near death, and weary with the long years. Then Jason, his son, said, "O my wife, to whom I confess I owe my life, though you have already given me everything, and the total of all your kindnesses is beyond any promises we made, let your incantations, if they can (what indeed can they not do?) reduce my own years and add them to my father's!" He could not restrain his tears. Medea was moved by the loving request, and the contrast with Aeetes, abandoned by her, came to mind. Yet, not allowing herself to be affected by such thoughts, she answered, "Husband, what dreadful words have escaped your lips? Do you think I can transfer any part of your life to another? Hecate would not allow it: nor is yours a just request. But I will try to grant a greater gift than the one you ask for, Jason. If only the Triple Goddess will aid me, and give her assent in person to this great act of daring, I will attempt to renew your father’s length of years, without need for yours."
