III. He who is quick to believe that he has thrown away his benefits, does really throw them away; but he who presses on and adds new benefits to his former ones, forces out gratitude even from a hard and forgetful breast. In the face of many kindnesses, your friend will not dare to raise his eyes; let him see you whithersoever he turns himself to escape from his remembrance of you; encircle him with your benefits. As for the power and property of these, I will explain it to you if first you will allow me to glance at a matter which does not belong to our subject, as to why the Graces are three in number, why they are sisters, why hand in hand, and why they are smiling and young, with a loose and transparent dress. Some writers think that there is one who bestows a benefit, one who receives it, and a third who returns it; others say that they represent the three sorts of benefactors, those who bestow, those who repay, and those who both receive and repay them. But take whichever you please to be true; what will this knowledge profit us? What is the meaning of this dance of sisters in a circle, hand in hand? It means that the course of a benefit is from hand to hand, back to the giver; that the beauty of the whole chain is lost if a single link fails, and that it is fairest when it proceeds in unbroken regular order. In the dance there is one, esteemed beyond the others, who represents the givers of benefits. Their faces are cheerful, as those of men who give or receive benefits are wont to be. They are young, because the memory of benefits ought not to grow old. They are virgins, because benefits are pure and untainted, and held holy by all; in benefits there should be no strict or binding conditions, therefore the Graces wear loose flowing tunics, which are transparent, because benefits love to be seen. People who are not under the influence of Greek literature may say that all this is a matter of course; but there can be no one who would think that the names which Hesiod has given them bear upon our subject. He named the eldest Aglaia, the middle one Euphrosyne, the third Thalia. Every one, according to his own ideas, twists the meaning of these names, trying to reconcile them with some system, though Hesiod merely gave his maidens their names from his own fancy. So Homer altered the name of one of them, naming her Pasithea, and betrothed her to a husband, in order that you may know that they are not vestal virgins. [Footnote: i.e. not vowed to chastity.]
