“ It is light, vaporous, veiled, discreet; it lends its charm to hidden things, invites curiosity, adds an attraction to moral beauties, and gives a grace to the speculations of conscience. In short, it partakes of sentiment, emotion, uncertainty, indefiniteness, and infinity; of dreams and of the ideal. And this is why it is, as it ought to be, the poetic and natural atmosphere in which Rembrandt's genius never ceased to dwell.
In very ordinary language and in its action common to all schools, chiaroscuro is the art of rendering the atmosphere visible, and painting an object enveloped with air. ”

“ The face, in the exquisite sweetness of a surrender to piety, reflects the bliss of Faith, of mystical voluptuousness, and divine ecstasy. The expression is religious, but the Virgin is human, and full of life in the firmness of her lines and the warmth of her flesh-tints. Beneath the suppleness of the drawing and the soft touches we recognize in Mary the Immaculate, the woman and even the Andalusian.
The whole work is a most harmonious and well-balanced composition, of the greatest opulence of colour, solidly laid in, and here and there lightly glazed over in the Venetian manner ”

“ Opposite the dying high-priest is the living though fainting victim, nearly dead at the belief that she is about to die. With her head resting on her shoulder, she has glided before the smoking altar. Her body has lost all rigidity on her bending legs, her arms hang down at her side; her glance is distracted; she has lost all volition in the use of her limbs; and she is there, sinking motionless, her throat scarcely distending with a breath, turning white under her crown of roses, which the painter's brush has made to pale in sympathy. ”

“ The fame of Leonardo had gone before him, and he was to model a colossal statue of Francesco, the first duke. As for Leonardo himself he came not as an artist at all, or careful of the fame of one; but as a player on the harp, a strange harp of silver of his own construction, shaped in some curious likeness to a horse's skull. The capricious spirit of Ludovico was susceptible to the charm of music, and Leonardo's nature had a kind of spell in it. Fascination is always the word descriptive of him. No portrait of his youth remains ”

“ The best, the only ones in which the hand of the master and the feeling of a master are to be recognized, are those which, from the depths of the canvas, shoot their vague eyes and the fine spark of their mobile glances at you; do not severely examine their construction, nor their plan, nor their bony structure; accustom yourself to the greyish pallor of their complexion, question them from afar as they also look at you from a distance, and if you want to know how they live, look at them as Rembrandt wants us to look at his human effigies, attentively and long, at their lips and eyes. ”

“ Sandro the poet knew it perfectly well and taught it to the no small comfort of Mr. Ruskin and his men. Giuditta, dainty, blue-eyed, a girl still and three years a widow, flits homeward through a spring landscape of grey and green and the smile of a milky sky, being herself the dominant of the chord, with her bough of slipt olive and her jagged scimitar, with her pretty blue fal-lals smocked and puffed, and her yellow curls floating over her shoulders. On her slim feet are the sandals that ravished his eyes; all her maiden bravery is dancing and fluttering like harebells in the wind. ”

“ Men go forth to their labours until the evening; but she is awake before them, and you might think that the sorrow in her face was at the thought of the whole long day of love yet to come. An emblematical figure of the wind blows hard across the grey water, moving forward the dainty-lipped shell on which she sails, the sea "showing his teeth" as it moves in thin lines of foam, and sucking in one by one the falling roses, each severe in outline, plucked off short at the stalk, but embrowned a little, as Botticelli's flowers always are. ”

“ What is his execution in the picture before us? Does he treat a stuff well? No. Does he express it ingeniously, or with liveliness, with its seams, folds, breaks, and tissue. Assuredly not. When he places a feather at the brim of a hat, does he give it the lightness and floating grace that we see in Van Dyck, or Hals, or Velasquez? Does he indicate by a little gloss on a dead ground, in their form, or feeling of the body, the human physiognomy of a well adjusted coat, rubbed by a movement or worn with use? ”

“ We do not think so. We consider that the authorities of the Museum are right a thousand times, when they possess such a chef-d'œuvre, not to neglect any precaution, however insignificant it may appear, to assure it a longer duration.
A fine engraving of this incomparable jewel gives a very exact idea of the arrangement and dominating qualities of the picture; but how can we translate in black and white the shimmering of material, the delicacy of tone, the colouring of those robes, rose, blue, and white, of exquisite harmony and incomparable finesse. ”

“ Their drawing, even without colour, is capable by itself of expressing all the solidity and all the vitality of the human structure. Look in this same hall at the four grisailles by Veronese—five or six women veiled or half-nude, all so strong and of such a frame that their thighs and arms would stifle a warrior in their embrace, and, nevertheless, their physiognomy is so simple or so proud that, despite their smile, they are virgins like Raphael's Venuses and Psyches.
The more we consider the ideal figures of Venetian art, the more we feel the breath of an heroic age behind us. ”

“ The future already mingles with the present; the real with the ideal. As soon as the image appears it has this double form. Not only is it exquisite, but not a feature is wanting. Does it not seem as if in thus fixing it from the first day, Rubens intended that neither he nor anyone else should forget it?
As for the rest, this is the sole mundane grace with which he has embellished this austere picture, slightly monkish, and absolutely evangelical in character, if by that is meant the gravity of sentiment and style, and if we remember the rigours that such a spirit must impose upon itself. ”

“ In this world of feminine fascination Botticelli loved everything. He knows the attraction of the toilet and of jewels, but he knows above all that no gem and no invention of man can rival the beauty of the female form. He was the first to understand the exquisite charm of silhouettes, the first to linger in expressing the joining of the arm and body, the flexibility of the hips, the roundness of the shoulders, the elegance of the leg, the little shadow that marks the springing of the neck, and, above all, the exquisite carving of the hand. ”

“ This time the genius of Michael Angelo simply attacked the infinite. The subject of this vast composition, the manner in which it is conceived and executed, the admirable variety and the learned disposition of the groups, the inconceivable boldness and firmness of the outlines, the contrast of light and shade, the difficulties, I might almost say the impossibilities vanquished, as if it were all mere play, and with a happiness that savours of prodigy, the unity of the whole and the perfection of the details, make The Last Judgment the most complete and the greatest picture in existence. ”

“ It is quite peculiar to Leonardo, and does not in the least recall the virgins of Perugino nor those of Raphael: the upper part of the head is spherical, the forehead well developed; the oval of the cheeks sweeps down to a delicately curved chin; the eyes with lowered lids are circled with shadow; the nose, although fine, is not in a straight line with the forehead, like those of the Greek statues; the nostrils seem to quiver as if palpitating with respiration. The mouth, rather large, has that vague, enigmatical and delicious smile which da Vinci gives to all the faces of his women ”

“ It is a remarkable picture, and leads us deep into the secrets of the human heart—a picture which in all times must be ranked amongst the master-works of art, and which to be intelligible needs no previous inquiry into the relative period and circumstances of the artists who created it. The landscape background, the rocky defile, the wooded declivity, and the trees laden with fruit, are all eminently beautiful. The eye would almost lose itself in this rich sense of still life if it were not constantly led back to the interest of the foreground. ”

“ But everything in this picture is food for admiration, even the atmosphere that envelops it and those innumerable and endless legions of cherubin that gravitate around the Virgin and the Word of God. The aureole that encircles the divine group shows nothing at first but dazzling and golden light; then, as it recedes from the centre, this light gradually pales and insensibly merges from the most intense gold into the purest blue, and is filled with those heads, chaste, innocent, and fervent, that spring beneath the brush of Raphael like the flowers at the breath of Spring. ”

“ Not the greatest picture in the world—not a work of the highest genius—but a performance so great, various, and admirable, so shrewd of humour, so wise of observation, so honest and complete of expression, that to have seen it has been a delight, and to remember it will be a pleasure for days to come. Well done, Bartholomeus Van der Helst! Brave, meritorious, victorious, happy Bartholomew, to whom it has been given to produce a masterpiece! ”

“ But what a magnificent illusion this picture presents! It must be seen in the Louvre so that the eyes may feast upon the clear and warm splendour of the canvas, the milky radiance of all those white priestly robes, the virginal light inundating the centre of the scene, palpitating and dying away on Callirhoé, enveloping her fainting body like the fading of day, and caressing that failing throat. The rays of light and the smoke all melt into one another; the temple smokes and the mists of incense ascend everywhere. Night is rolling above the day. ”

“ In fact, these angels seem to be painted as an afterthought, for, laid in with a light brush, they scarcely cover the clouds, but allow the underlying pigment to show through.
Little wings of vivid tint complete these aërial creatures, always living around Raphael and always ready to come from his brush. Although held to nature by the most intimate ties, although perhaps too familiar in attitude and manner, they are yet supernatural by the clearness of their intelligence and by the power of their admiration. We are enchanted with their candour and beauty. They are full of zeal and enthusiasm ”

“ But this was not enough for him; he is a visionary painter, and in his visionariness he resembles Dante. Giotto, the tried companion of Dante, Masaccio, Ghirlandaio even, do but transcribe with more or less refining the outward image; they are dramatic, not visionary painters; they are almost impassive spectators of the action before them. But the genius of which Botticelli is the type usurps the data before it as the exponents of ideas, moods, visions of its own; with this interest it plays fast and loose with those data, rejecting some and isolating others, and always combining them anew. ”

“ In my opinion, it is that principal figure that is the key to the picture; it is for this figure that everything has been done, and this it is, above all, that we must interrogate if we wish to know Botticelli's meaning. Evidently it is neither Venus, nor Spring; and the precision of the features, and the fidelity of the smallest details of the costume make us believe that we are in the presence of a veritable portrait.... Around her, Nature adorns herself with flowers; Spring and the Graces surround her like a train of Fays. ”

“ Distinction,—that is the gift par excellence, the dominating quality of this artist, that which constitutes his individuality, that which marks with an indelible imprint all his glorious works, from the first gropings of the pupil of Rubens to those immortal images of Charles I., his family, and his court.
Whether he belongs to the highest spheres of society or whether he comes from the simple bourgeoisie of Antwerp, the model receives from Van Dyck's brush the most aristocratic mien. One would insist that the painter spent his life only in a world of gentlemen and patricians. ”

“ The fancy of a perpetual life, sweeping together ten thousand experiences, is an old one; and modern thought has conceived the idea of humanity as wrought upon by, and summing up in itself, all modes of thought and life. Certainly Lady Lisa might stand as the embodiment of the old fancy, the symbol of the modern idea.
During these years at Florence Leonardo's history is the history of his art; he himself is lost in the bright cloud of it. The outward history begins again in 1502, with a wild journey through central Italy, which he makes as the chief engineer of Cæsar Borgia. ”

“ This Jehovah, like a divine bird appearing head-foremost and with body horizontally foreshortened beneath a wave of drapery flying open like wings, astonishes us by its sublime boldness; if it is possible for the brush of a human being to give a countenance to divinity, certainly Titian has succeeded. Unlimited power and imperishable youth radiate from that white-bearded face that need only nod for the snows of eternity to fall: not since the Olympian Jove of Phidias has the lord of heaven and earth been represented more worthily. ”

“ Here are two points miraculously co-uniting; fierce society, with the feeling of solitude still absolute; noon-day revelations, with the accidents of the dull grey dawn unquenched and lingering; the present Bacchus with the past Ariadne; two stories, with double Time; separate, and harmonizing. Had the artist made the woman one shade less indifferent to the God; still more, had she expressed a rapture at his advent, where would have been the story of the mighty desolation of the heart previous? ”

“ The arrangement of the draperies is of that exquisite and precious taste that characterizes da Vinci. An agrafe in the form of a medallion fastens on the breast the ends of a mantle lifted up by the arms which thus produce folds full of nobility and elegance.
The angel who is pointing out the Infant Jesus to the little Saint John has the sweetest, the finest, and the proudest head that brush ever fixed upon canvas. He belongs, if we may so express it, to the highest celestial aristocracy. One might say he was a page of high birth accustomed to place his foot on the steps of a throne. ”

“ And yet, admire the omnipotence of genius! With nothing but a single episode in a restricted space, and solely by the expression of the human body, the artist has succeeded in striking you with astonishment and terror, and in making you really a spectator of the supreme catastrophe.
At the base of the picture, very nearly in the centre, you perceive the boat of the Inferno, a fantastic reminiscence borrowed from Pagan tradition, in accordance with which first the poet and then the painter were pleased to clothe an accursed being with the form and occupation of Charon. ”

“ All this is imposing, and our imagination becomes excited rather more than usual when, in the centre of the Place Vert, we see the statue of Rubens and, farther on, the old basilica where are preserved the triptychs which, humanly speaking, have consecrated it.
The statue is not a masterpiece; but it is he, in his own home. Under the form of a man, who was nothing but a painter, with the sole attributes of a painter, in perfect truth it personifies the sole Flemish sovereignty which has neither been contested nor menaced, and which certainly never will be. ”

“ The Madonna of Albrecht Dürer in her sad and somewhat constrained gracefulness, with her tired features, interesting rather than beautiful, her air of a matron rather than a Virgin, her German and bourgeoise frankness, her tight garments and her symmetrically broken folds, almost always accompanied by a rabbit, an owl, or an ape, through some vague memory of Germanic pantheism, may she not be the woman whom he would have loved and preferred to all others, and does she not also exceedingly well represent the very genius of the artist? ”

“ It is hard not to connect with these designs of the elder by-past master, as with its germinal principle, the unfathomable smile, always with a touch of something sinister in it, which plays over all Leonardo's work. Besides, the picture is a portrait. From childhood we see this image defining itself on the fabric of his dreams; and but for express historical testimony, we might fancy that this was but his ideal lady, embodied and beheld at last. What was the relationship of a living Florentine to this creature of his thought? ”

“ Between two green curtains drawn to either side of the picture, amid an aureole of innumerable cherubin, the Virgin is seen standing upon the clouds, with her son in her arms, showing him to the world as its Redeemer and Sovereign Judge. Lower down, St. Sixtus and St. Barbara are kneeling on the clouds on either side. Nothing is visible of the earth, but it is divined by the gestures and glances of the two saints, who are pointing to the multitude for whom they are imploring the divine mercy. ”
