Euripides’s Iolaus of a feeble, superannuated old man, by means of a certain prayer, became on a sudden youthful and strong for battle; but the Stoics’ wise man was yesterday most detestable and the worst of villains, but today is changed on a sudden into a state of virtue, and is become of a wrinkled, pale fellow, and, as Aeschylus speaks, Of an old sickly wretch with stitch in’s back, Distent with rending pains as on a rack, a gallant, god-like, and beauteous person.
