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.
But among the more youthful heads there is one at Florence which Love chooses for its own--the head of a young man, which may well be the likeness of Andrea Salaino, beloved of Leonardo for his curled and waving hair--belli capelli ricci e inanellati-- and afterwards his favourite pupil and servant. Of all the interests in living men and women which may have filled his life at Milan, this attachment alone is recorded. And in return Salaino identified himself so entirely with Leonardo, that the picture of Saint Anne, in the Louvre, has been attributed to him. It illustrates Leonardo's usual choice of pupils, men [117] of some natural charm of person or intercourse like Salaino, or men of birth and princely habits of life like Francesco Melzi--men with just enough genius to be capable of initiation into his secret, for the sake of which they were ready to efface their own individuality. Among them, retiring often to the villa of the Melzi at Canonica al Vaprio, he worked at his fugitive manuscripts and sketches, working for the present hour, and for a few only, perhaps chiefly for himself. Other artists have been as careless of present or future applause, in self-forgetfulness, or because they set moral or political ends above the ends of art; but in him this solitary culture of beauty seems to have hung upon a kind of self-love, and a carelessness in the work of art of all but art itself. Out of the secret places of a unique temperament he brought strange blossoms and fruits hitherto unknown; and for him, the novel impression conveyed, the exquisite effect woven, counted as an end in itself--a perfect end.
