No work of literature is so closely tied in with painting than Marcel Proust’s In Search of Lost Time. In the first volume, Swann’s Way, Charles Swann finds himself in an obsessive relationship with Odette de Crécy. At one point, he compares his inamorata with Zipporah, Jethro’s daughter, in Sandro Botticelli’s “Life of Moses.”

On his way to the house, as always when he knew that they were to meet, he formed a picture of her in his mind; and the necessity, if he was to find any beauty in her face, of fixing his eyes on the fresh and rosy protuberance of her cheekbones, and of shutting out all the rest of those cheeks which were so often languorous and sallow, except when they were punctuated with little fiery spots, plunged him in acute depression, as proving that one’s ideal is always unattainable, and one’s actual happiness mediocre. He was taking her an engraving which she had asked to see. She was not very well; she received him, wearing a wrapper of mauve crêpe de Chine, which draped her bosom, like a mantle, with a richly embroidered web. As she stood there beside him, brushing his cheek with the loosened tresses of her hair, bending one knee in what was almost a dancer’s pose, so that she could lean without tiring herself over the picture, at which she was gazing, with bended head, out of those great eyes, which seemed so weary and so sullen when there was nothing to animate her, Swann was struck by her resemblance to the figure of Zipporah, Jethro’s Daughter, which is to be seen in one of the Sistine frescoes. He had always found a peculiar fascination in tracing in the paintings of the Old Masters, not merely the general characteristics of the people whom he encountered in his daily life, but rather what seems least susceptible of generalisation, the individual features of men and women whom he knew, as, for instance, in a bust of the Doge Loredan by Antonio Rizzo, the prominent cheekbones, the slanting eyebrows, in short, a speaking likeness to his own coachman Rémi; in the colouring of a Ghirlandaio, the nose of M. de Palancy; in a portrait by Tintoretto, the invasion of the plumpness of the cheek by an outcrop of whisker, the broken nose, the penetrating stare, the swollen eyelids of Dr. du Boulbon. Perhaps because he had always regretted, in his heart, that he had confined his attention to the social side of life, had talked, always, rather than acted, he felt that he might find a sort of indulgence bestowed upon him by those great artists, in his perception of the fact that they also had regarded with pleasure and had admitted into the canon of their works such types of physiognomy as give those works the strongest possible certificate of reality and trueness to life; a modern, almost a topical savour; perhaps, also, he had so far succumbed to the prevailing frivolity of the world of fashion that he felt the necessity of finding in an old masterpiece some such obvious and refreshing allusion to a person about whom jokes could be made and repeated and enjoyed to-day. Perhaps, on the other hand, he had retained enough of the artistic temperament to be able to find a genuine satisfaction in watching these individual features take on a more general significance when he saw them, uprooted and disembodied, in the abstract idea of similarity between an historic portrait and a modern original, whom it was not intended to represent. However that might be, and perhaps because the abundance of impressions which he, for some time past, had been receiving—though, indeed, they had come to him rather through the channel of his appreciation of music—had enriched his appetite for painting as well, it was with an unusual intensity of pleasure, a pleasure destined to have a lasting effect upon his character and conduct, that Swann remarked Odette’s resemblance to the Zipporah of that Alessandro de Mariano, to whom one shrinks from giving his more popular surname, now that ‘Botticelli’ suggests not so much the actual work of the Master as that false and banal conception of it which has of late obtained common currency. He no longer based his estimate of the merit of Odette’s face on the more or less good quality of her cheeks, and the softness and sweetness—as of carnation-petals—which, he supposed, would greet his lips there, should he ever hazard an embrace, but regarded it rather as a skein of subtle and lovely silken threads, which his gazing eyes collected and wound together, following the curving line from the skein to the ball, where he mingled the cadence of her neck with the spring of her hair and the droop of her eyelids, as though from a portrait of herself, in which her type was made clearly intelligible.

He stood gazing at her; traces of the old fresco were apparent in her face and limbs, and these he tried incessantly, afterwards, to recapture, both when he was with Odette, and when he was only thinking of her in her absence; and, albeit his admiration for the Florentine masterpiece was probably based upon his discovery that it had been reproduced in her, the similarity enhanced her beauty also, and rendered her more precious in his sight. Swann reproached himself with his failure, hitherto, to estimate at her true worth a creature whom the great Sandro would have adored, and counted himself fortunate that his pleasure in the contemplation of Odette found a justification in his own system of aesthetic. He told himself that, in choosing the thought of Odette as the inspiration of his dreams of ideal happiness, he was not, as he had until then supposed, falling back, merely, upon an expedient of doubtful and certainly inadequate value, since she contained in herself what satisfied the utmost refinement of his taste in art. He failed to observe that this quality would not naturally avail to bring Odette into the category of women whom he found desirable, simply because his desires had always run counter to his aesthetic taste. The words ‘Florentine painting’ were invaluable to Swann. They enabled him (gave him, as it were, a legal title) to introduce the image of Odette into a world of dreams and fancies which, until then, she had been debarred from entering, and where she assumed a new and nobler form. And whereas the mere sight of her in the flesh, by perpetually reviving his misgivings as to the quality of her face, her figure, the whole of her beauty, used to cool the ardour of his love, those misgivings were swept away and that love confirmed now that he could re-erect his estimate of her on the sure foundations of his aesthetic principles; while the kiss, the bodily surrender which would have seemed natural and but moderately attractive, had they been granted him by a creature of somewhat withered flesh and sluggish blood, coming, as now they came, to crown his adoration of a masterpiece in a gallery, must, it seemed, prove as exquisite as they would be supernatural.
