“What is it,” asks Bernhard Berenson, “that makes us return to this sheet with ever-renewed, ever-increased pleasure? Surely it is not the hideous faces of most of the figures and their scarcely less hideous bodies. Nor is it the pattern as decorative design, which is of great beauty indeed, but not at all in proportion to the spell exerted upon us. Least of all is it--for most of us--an interest in the technique or history of engraving. No, the pleasure we take in these savagely battling forms arises from their power to directly communicate life, to immensely heighten our sense of vitality. Look at the combatant prostrate on the ground and his assailant, bending over, each intent on stabbing the other. See how the prostrate man plants his foot on the thigh of his enemy and note the tremendous energy he exerts to keep off the foe, who, turning as upon a pivot, with his grip on the other’s head, exerts no less force to keep the advantage gained. The significance of all these muscular strains and pressures is so rendered that we cannot help realizing them; we imagine ourselves imitating all the movements and exerting the force required for them--and all without the least effort on our side. If all this without moving a muscle, what should we feel if we too had exerted ourselves? And thus while under the spell of this illusion--this hyperæsthesia not bought with drugs and not paid for with cheques drawn on our vitality--we feel as if the elixir of life, not our own sluggish blood, were coursing through our veins.”[6] [6] Florentine Painters of the Renaissance.
