Take again another head, still more full of sentiment, but of a different kind, a little drawing in red chalk which every one will remember who has examined at all carefully the drawings by old masters at the Louvre. It is a face of doubtful sex, set in the shadow of its own hair, the cheek-line in high light against it, with something voluptuous and full in the eye-lids and the lips. Another drawing might pass for the same face in childhood, with parched and feverish lips, but much sweetness in the loose, short- waisted childish dress, with necklace and bulla, and in the daintily bound hair. We might take the thread of suggestion which these two drawings offer, when thus set side by side, and, following it through the drawings at Florence, Venice, and Milan, construct a sort of series, illustrating better than anything else Leonardo's type of womanly beauty. Daughters of Herodias, with their fantastic head-dresses knotted and folded so strangely to leave the [116] dainty oval of the face disengaged, they are not of the Christian family, or of Raphael's. They are the clairvoyants, through whom, as through delicate instruments, one becomes aware of the subtler forces of nature, and the modes of their action, all that is magnetic in it, all those finer conditions wherein material things rise to that subtlety of operation which constitutes them spiritual, where only the final nerve and the keener touch can follow. It is as if in certain significant examples we actually saw those forces at their work on human flesh. Nervous, electric, faint always with some inexplicable faintness, these people seem to be subject to exceptional conditions, to feel powers at work in the common air unfelt by others, to become, as it were, the receptacle of them, and pass them on to us in a chain of secret influences.
