Nevertheless, taken for all in all, Overbeck and Cornelius must be accounted most fortunate in their intellectual companionship. The habit was, when gathered socially together at the Embassy in the Palazzo Caffarelli, to read books, talk of pictures, and to consort together generally for the furtherance of the great art revival in which Niebuhr and Bunsen believed fervently. The attachment became mutual, the intercourse was prized on both sides. Niebuhr writes of Cornelius and his wife: "They are, strictly speaking, intimate family friends;" and again he says: "The society of Cornelius and Overbeck gives an inspiring variety to the day's occupations, and one or other of these intellectual companions seldom fails to join our evening walks." In another letter we read: "Cornelius of Düsseldorf, Platner from Leipzig, Koch from the Tyrol, Overbeck from Lübeck, Mosler from Coblentz, and William Schadow from Berlin, were assembled at Bunsen's in the apartments of the painter Brandis: in different ways and degrees we are attached to them all, and we think them men of talent. Their society is the only pleasure we derive from human beings in Rome." The young artists are found to be wholly without worldly wisdom, a charge to which at least Overbeck might readily plead guilty. Niebuhr further declares: "I confidently believe we are on the eve of a new era of Art in Germany, similar to the sudden bloom of our literature in the eighteenth century." He discerned in the movement an unaccustomed spiritual phenomenon—one of those manifestations of the national mind from time to time found in the history of humanity. He felt once more an outburst of the intellectual life of Germany, a rising again of the force of genius which had impelled Lessing, Kant, and Goethe, which had given birth to profound philosophy and science, and had animated a whole people with patriotism and a spirit of self‑sacrifice to do battle amid national songs and hymns, even to the death, in the cause of the King and the Fatherland. Bunsen testifies how Niebuhr showed his affection and care for the Prussian and German disciples of art; he considered it an agreeable part of his duty and vocation to render them assistance, to encourage them in their studies, to give them the time of which he was so sparing to men of mere show and fashion, also to render them pecuniary assistance when necessary. To Niebuhr belongs the honour of having been the first to recognise the new school at the moment when it was "despised, derided, and vituperated." He befriended the men who had to fight their way against shallowness and wickedness, against the low and false taste of connoisseurs and patrons, till the day came when the martyrs of an exalted aspiration gained the attention and admiration of the world.

Nor in numbering friends must be forgotten Frederick Schlegel, the avowed champion of the new school. The critic was not without connecting links and antecedents; he had made himself son‑in‑law of the Jewish philosopher Moses Mendelssohn, and stepfather of the painter Philip Veit; and he further qualified himself for his critical duties by joining the Roman Catholic Church. Overbeck and this rhapsodist on Christian Art were naturally close allies; each was of use to the other, and gave and received in turns. The artist strove, it is said, to embody in pictorial form his friend's teachings; the two, in fact, moved in parallel lines. Schlegel urged that the new style must be emulative and aspiring, ever possessed of lofty ideas. Believe not, he writes, that the glory of art has passed away. The hope is not vain that there comes a rekindling of former fires; art uprising from the dark night breaks as the morning's dawn; "a new life can spring only from the depths of a new love." Let us hold that Art like Nature renews her youth. The soul alone can comprehend the truly beautiful; the eye gazes but on the material veil—the union of the inner soul with the outward form constitutes the noblest art. Nowhere are to be found more eloquent utterances on "the Bond between Art and the Church," but in all is overlooked the simple fact that "the Celestial light" cannot be made appreciable to mortal eye otherwise than through the medium of matter, and according to the laws of vision. And to such oversight is greatly to be ascribed the infirmities of Overbeck and his school. It is forgotten that the most holy of motives cannot save a picture which is not good as a picture. Schlegel discusses the question, What is needed by the Christian painter? The following phrenzy, though wordy, is worth reading:—

"The answer is that the beautiful truths of the Christian faith should not be received into the mind as merely lifeless forms, in passive acquiescence to the teaching of others: they must be embraced with an earnest conviction of their truth and reality, and bound up with each individual feeling of the painter's soul. Still even the influence of devotion is not alone sufficient; for however entirely religion may be felt to compensate for all that is wanting to our earthly happiness, much more is required to form a painter. I know not how better to designate that other element, without which mere technical skill, and even correct ideas, will be unavailing, than by calling it the inborn light of inspiration. It is something quite distinct from fertility of invention, or magic of colouring, rare and valuable as is the latter quality in painting. It is no less distinct from skill in the technicalities of design and from the natural feeling for beauty inherent in some susceptible minds. The poet and the musician should also be inspired, but their inspiration is more the offspring of human emotion; the painter's inspiration must be an emanation of celestial light: his very soul must, so to speak, become itself illumined, a glowing centre of holy radiance, in whose bright beams every material object should be reflected; and even his inmost conceptions and daily thoughts must be interpenetrated by its brightness and remodelled by its power. This indwelling light of the soul should be recognised in every creation of his pencil, expressive as a spoken word; and in this lies the peculiar vitality of Christian beauty, and the cause of the remarkable difference between Classic and Christian art." "Physical beauty is employed by the Christian painter but as a material veil, from beneath which the hidden divinity of the soul shines forth, illuminating all mortal life with the higher spirituality of love."

A kindly and timely commission came to the masters of the German Brotherhood—Overbeck, Cornelius, Veit, and Schadow—from the Prussian Consul, Bartholdi. Personal relations, with the desire of giving the untried painters an opportunity of proving what good was in them, prompted the charge to decorate with frescoes a room in the Casa Bartholdi, situated on the brow of the Pincian Hill.[6] The Prussian Consul was in a roundabout way connected with Philip Veit and Frederick Schlegel, whose mutual relationship has been already recounted; his wife was sister of the philosopher Moses Mendelssohn, and aunt of the illustrious musician, and sundry intermarriages had made, as it were, a compact in literature and art between the families of Bartholdi, Mendelssohn, Veit, and Schlegel.[7] The chosen sphere of operations was comparatively narrow; the small room in an upper story, now of historic interest, is not more than twenty‑four feet square. The situation is inviting; the beauties of nature are usually found proximate with the beauties of art, and here the windows command a panorama sweeping from the Pincian to the Tiber, and embracing St. Peter's, the Vatican, St. Angelo, and the Capitol. The topic chosen for these wall pictures was the Story of Joseph and his Brethren—a theme conveniently accommodating to any existing diversities in creeds or styles. The technical process adopted was fresco, a monumental art, the revival of which formed part of the mission of the German fraternity. The arduous undertaking was commenced and carried out in strict accordance with historic precedents. Preliminary studies were made, and well‑matured cartoons on the scale of the ultimate pictures were perfected. To the lot of Overbeck fell Joseph sold by his Brethren,[8] and The Seven Years of Famine.

It has been my pleasure to visit and revisit these wall‑paintings over a period of a quarter of a century, and growing experience does but enhance my admiration. They fulfil the first requirements of wall decoration: the story is told lucidly and concisely; the style is simple, noble; accidents are held subordinate to essentials; the compositions are distributed symmetrically; the colour, though a little crude, is brought into somewhat agreeable unity; the light and shade are not focussed at one point, but carried evenly over the whole surface; and the treatment inclines sufficiently to the flat to keep the compositions down on the wall. The finished pictures of the four masters vary in dimensions. The lengths range from eight to seventeen feet, the height is mostly about eight feet; the figures do not exceed five feet. The lines bounding the figures and draperies are firm and incisive. Accordant with the practice of the old fresco‑painters, each day's work is marked and discernible by the joinings in the plaster, and the junctions between the dry plaster of one day and the wet plaster of the next are appropriately fixed at the points where the subject breaks off readily and can be resumed most easily. The technique is thoroughly mastered, and, barring some surface cracks, the paintings are in as perfect condition as when they came from the artists' hands. The chief defect is a somewhat crude opacity of pigments, a characteristic belonging to the debased period of wall‑painting rather than to the "fresco buono et puro" of Giotto, Luini, and Pinturicchio.

Another point to be remarked is that the frescoes in the Casa Bartholdi show that the four painters—Overbeck, Cornelius, Veit, and Schadow—worked here at the outset of their career in remarkable unison. In the course of years they diverged widely, but as yet the school collectively dominates over the artist individually. The Brethren had formed themselves equally on the same originals, and had scarcely found time to take their several departures from nature. Indeed, the actual presence of nature comes almost as a surprise in these compositions. Overbeck's figures are manifestly more or less studied from the life, only, according to his habitual practice, he has taken pains to eliminate from his models any individual accidents which marred the generic form, softening down angularity and ruggedness into pervading grace and beauty. Here and there are traces of affectation, together with a feebleness incident to the painter's weak physique which stands in utmost contrast with the force of Cornelius. Overbeck mostly shunned action and dramatic intensity, and here the figures in their movements depart but slightly from the equilibrium of repose. As a religious artist, the New Testament was more within his sphere than the Old. Thus the outrage committed against Joseph by his brethren is toned down into a calm, orderly transaction; placidity reigns throughout; all is brought into keeping with the painter's spirit of gentleness.

The Casa Bartholdi frescoes,[9] when finished, produced a most favourable impression in Rome; the cause of the Germans was greatly strengthened, and the opposite party felt the defeat. The Italians, too, were taken by surprise to find themselves beaten by foreigners on their own ground. A natural consequence of the success was further commissions, and the fortune no less than the fame of the revivalists was made. Singularly enough the modern Romans came forward as the next patrons. Niebuhr, writing from Rome in 1817, says: "It is a significant fact that some foreigners, even Italians, are beginning to pay attention to the works of our friends." It is well known that the Romans had been addicted for centuries to mural painting in palaces, villas and garden‑houses: Raphael was employed to decorate the Farnesina; Guido and Annibale Carracci painted the ceilings of the Farnese and of the Rospigliosi Palaces. Emulating these illustrious examples, Prince Massimo commissioned Overbeck, Cornelius, Veit, and Schnorr to cover the walls and ceilings of his Garden Pavilion near St. John Lateran with frescoes illustrative of Tasso, Dante, and Ariosto. Not only the themes, but the local surroundings were inspiring. The Villa Massimo is a site only possible in Rome. When the artists in the morning came to work, before their view opened a panorama embracing the Claudian Aqueduct, St. John Lateran, the Church of Sta. Croce in Gerusalemme, the old Walls of Rome, with cypresses and stone pines around, and the Alban Hills beyond. The Pavilion assigned to the painters stands in the Villa garden, with the accustomed growth and fragrance of orange‑trees, magnolias, azaleas, roses, and violets. Overbeck entered on the work with poetic ardour.

The Massimo Pavilion is little more than three rooms standing on the ground; the first, indeed, is an Entrance Hall, and therein Schnorr painted copiously from Ariosto. On the left a door leads to the room assigned to Cornelius for the illustration of Dante: the ceiling fell to the lot of Veit. On the right another door opens to a corresponding room of like dimensions, set apart to Overbeck and Tasso's Jerusalem Delivered.[10] This small interior is not more than fifteen feet square, and the wall‑spaces are much broken up by doors and windows, so that only one of the four sides remained disencumbered. The compositions are eleven in number, and are unequal alike in size and merit. The largest and most noteworthy is fifteen feet long by ten feet high, representing the Meeting of Godfrey de Bouillon and Peter the Hermit. The narrative is lucidly told, the picture well put together, and the successive planes of distance are duly marked. Altogether the fundamental principles of wall‑decoration are clearly understood in this the most complex composition yet attempted by the painter. Another thoroughly studied design is Sophronio and Olindo on the Funeral Pyre delivered by Clorinda.[11] The action has more than usual force and movement, and the undraped figures are drawn with severe exactitude. Presiding over the whole series, in the middle of the ceiling, is an allegorical figure of Jerusalem Delivered.[12] An angel on either side unlooses the fetters of an innocent placid maiden crowned with thorns. These frescoes, notwithstanding their situation in a cold, damp garden‑house, remained, when I saw them last, in January, 1878, in sound condition: thus once more we find Overbeck, equally with Cornelius, to have been solidly grounded in the method of wall‑painting.

I must confess that I have always been disappointed with this Tasso Room.[13] One reason is that the carrying out of the original designs was delegated to an inferior brush. Overbeck was not in strong health; he worked slowly, and when other commissions came in, some more to his liking, such as that for the church picture at Assisi, he felt overburdened, and wished to be released from a task that had grown wearisome. The work, began about 1817, had dragged on for ten years, till at last Overbeck made a deliberate call on good and friendly Joseph Führich, and requested that he would complete the unfinished frescoes. The proposal, naturally felt as an honour, was gratefully acceded to. After this distance of time it becomes difficult to determine how far this worthy substitute must be held responsible for much that is to be regretted on these walls. For some of the compositions the master had made nothing more than sketches or indications, and at least three must be laid to the charge of the scholar. Führich was for Overbeck what Giulio Romano had been for Raphael, and the Tasso Room suffered the same degradation as the latest stanza in the Vatican.

The Tasso Room may be taken as a measure of Overbeck's capacity. This "cyclus," or series, shows the painter's power of sustained thought and faculty of invention. Much, doubtless, is compilation, yet something remains of originality. The best passages are those not borrowed from old pictures, but taken from life, which makes the regret all the greater that here and in the sequel nature was not trusted more implicitly. On the whole, these compositions leave the impression that Overbeck had not mental force or physical stamina sufficient for the task. It is true that the presence of a lyrical spirit is felt; but scenes of Romance need more fire and passion; the deeds of Chivalry were not enacted in a cloister. Perhaps self‑knowledge wisely counselled Overbeck to quit the regions of creative imagination. With greater peace of mind he trod in the future, the safer paths of Christian Art, wherein precedent and authority served as his guide and support.
