189. Thirdly. The Greek Aphrodite is entirely calm, and looks straight forward. Not one feature of her face is disturbed, or seems ever to have been subject to emotion. The Italian Aphrodite looks up, her face all quivering and burning with passion and wasting anxiety. The Greek one is quiet, self-possessed, and self-satisfied: the Italian incapable of rest; she has had no thought nor care for herself; her hair has been bound by a fillet like the Greek's; but it is now all fallen loose, and clotted with the sea, or clinging to her body; only the front tress of it is caught by the breeze from her raised forehead, and lifted, in the place where the tongues of fire rest on the brows, in the early Christian pictures of Pentecost, and the waving fires abide upon the heads of Angelico's seraphim. 190. There are almost endless points of interest, great and small, to be noted in these differences of treatment. This binding of the hair by the single fillet marks the straight course of one great system of art method, from that Greek head which I showed you on the archaic coin of the seventh century before Christ, to this of the fifteenth of our own era;--nay, when you look close, you will see the entire action of the head depends on one lock of hair falling back from the ear, which it does in compliance with the old Greek observance of its being bent there by the pressure of the helmet. That rippling of it down her shoulders comes from the Athena of Corinth; the raising of it on her forehead, from the knot of the hair of Diana, changed into the vestal fire of the angels. But chiefly, the calmness of the features in the one face, and their anxiety in the other, indicate first, indeed, the characteristic difference in every conception of the schools, the Greek never representing expression, the Italian primarily seeking it; but far more, mark for us here the utter change in the conception of love; from the tranquil guide and queen of a happy terrestrial domestic life, accepting its immediate pleasures and natural duties, to the agonizing hope of an infinite good, and the ever mingled joy and terror of a love divine in jealousy, crying, "Set me as a seal upon thine heart, as a seal upon thine arm; for love is strong as death, jealousy is cruel as the grave." [Illustration: XIV. APOLLO AND THE PYTHON. HERACLES AND THE NEMEAN LION.] The vast issues dependent on this change in the conception of the ruling passion of the human soul, I will endeavor to show you on a future occasion: in my present Lecture, I shall limit myself to the definition of the temper of Greek sculpture, and of its distinctions from Florentine in the treatment of any subject whatever, be it love or hatred, hope or despair. These great differences are mainly the following. 191. First. A Greek never expresses momentary passion; a Florentine looks to momentary passion as the ultimate object of his skill.
