The Art-work of the Middle Ages manifests this mastery of mere material by mind, and it is very often its only mission. The epic poems of this period may be easily classed according to the degree of this subjection or influence. There can be no discussion here of lyrical and dramatic poems, for the latter did not exist, and the former are as like in every age as are the songs of nightingales in spring.
Although the epic poetry of the Middle Ages was divided into sacred and profane, both were altogether Christian according to their kind; for if sacred poesy sang of the Jewish race and its history, the only race which was regarded as holy, or of the heroes and legends of the Old and New Testaments, and, in brief, the Church—still all the life of the time was reflected in profane poetry with its Christian views and action. The flower of the religious poetic art in the German Middle Ages is perhaps Barlaam and Josaphat, in which the doctrine of abnegation, of abstinence, and the denial and contempt of all worldly glory, is set forth most consistently. Next to this I would class the The Eulogium of St. Hanno (Lobgesang auf den heiligen Anno) as the best of the religious kind; but this is of a far more secular character, differing from the first as the portrait of a Byzantine saint differs from an old German one. As in those Byzantine pictures, so we see in Barlaam and Josaphat the utmost simplicity; there is no perspective side-work, and the long, lean, statue-like forms and the idealistic serious faces come out strongly drawn, as if from a mellow gold ground. On the other hand, in the song of praise of St. Hanno, the side-work or accessories are almost the subject, and, notwithstanding the grandeur of the plan, the details are treated in the minutest manner, so that we know not whether to admire in it the conception of a giant or the patience of a dwarf. But the evangel-poem of Ottfried, which is generally praised as the masterpiece of sacred poetry, is far less admirable than the two which I have mentioned.
In profane poetry we find, as I have already signified, first the cycle of sagas of the Nibelungen and the Heldenbuch, or Book of Heroes. In them prevails all the pre-Christian manner of thought and of feeling; in them rude strength has not as yet been softened by chivalry. There the stern Kempe-warriors of the North stand like stone images, and the gentle gleam and the more refined breath of Christianity have not as yet penetrated their iron armor. But little by little a light dawns in the old Teutonic forest; the ancient idolatrous oak-trees are felled, and we see a brighter field of battle where Christ wars with the heathen. This appears in the saga-cycle of Charlemagne, in which what we really see is the Crusades reflecting themselves with their religious influences. And now from the spiritualizing power of Christianity, chivalry, the most characteristic feature of the Middle Ages, unfolds itself, and is at last sublimed into a spiritual knighthood. This secular knighthood appears most attractively glorified in the sagacycle of King Arthur, in which the sweetest gallantry, the most refined courtesy, and the most adventurous passion for combat prevail. Among the charmingly eccentric arabesques and fantastic flower-pictures of this poem we are greeted by the admirable Iwain, the all-surpassing Lancelot du Lac, and the bold, gallant, and true, but somewhat tiresome, Wigalois. Nearly allied and interwoven with this cyclus of sagas is that of the Holy Grail, in which the spiritual knighthood is glorified; and in this epoch we meet three of the grandest poems of the Middle Ages, the Titurel, the Parsifal, and the Lohengrin. Here indeed we find ourselves face to face with Romantic Poetry. We look deeply into her great sorrowing eyes; she twines around us, unsuspectingly, her fine scholastic nets, and draws us down into the bewildering, deluding depths of medieval mysticism.
At last, however, we come to poems of that age which are not unconditionally devoted to Christian spiritualism; nay, it is often indirectly reflected on, where the poet disentangles himself from the bonds of abstract Christian virtues and plunges delighted into the world of pleasure and of glorified sensuousness; and it is not the worst poet, by any means, who has left us the principal work thus inspired. This is Tristan and Isolde; and I must declare that Gottfried von Strassburg, the composer of this most beautiful poem of the Middle Ages, is perhaps also its greatest poet, towering far above all the splendor of Wolfram von Eschenbach, whom we so admire in Parsifal and the fragments of Titurel. We are at last permitted to praise Gottfried unconditionally, though in his own time his book was certainly regarded as godless, and similar works, among them the Lancelot, were considered as dangerous. And some very serious results did indeed ensue. The fair Francesca da Polenta and her handsome friend had to pay dearly for the pleasure of reading on a summer day in such a book; but the trouble came not from the reading, but from their suddenly ceasing to read.
There is in all these poems of the Middle Ages a marked character which distinguishes them from those of Greece and Rome. We characterize this difference by calling the first Romantic and the other Classic. Yet these appellations are only uncertain rubrics, and have led hitherto to the most discouraging, wearisome entanglements, which become worse since we give to antique poetry the designation of "Plastic," instead of "Classic." From this arose much misunderstanding; for, justly, all poets should work their material plastically, be it Christian or heathen; they should set it forth in clear outlines; in short, plastic form should be the main desideratum in modern Romantic art, quite as much as in the ancient. And are not the figures in the Divina Commedia of Dante or in the pictures of Raphael as plastic as those in Virgil? The difference lies in this, that the plastic forms in ancient art are absolutely identical with the subject or the idea which the artist would set forth, as, for example, that the wanderings of Ulysses mean nothing else than the journeyings of a man named Odysseus, who was son of Laërtes and husband of Penelope; and further, that the Bacchus which we see in the Louvre is nothing else than the graceful, winsome son of Semele, with audacious melancholy in his eyes and sacred voluptuousness on his soft and arching lips. It is quite otherwise in Romantic art, in which the wild wanderings of a knight have ever an esoteric meaning, symbolizing perhaps the erring course of life. The dragon whom he overcomes is sin; the almond which from afar casts comforting perfume to the traveler is the Trinity, God the Father, God the Son, and God the Holy Ghost, which are three in one, as shell, fibre, and kernel make one nut. When Homer describes the armor of a hero, it is a good piece of work, worth such and such a number of oxen; but when a monk of the Middle Ages describes in his poems the garments of the Mother of God, one may be sure that by this garb he means as many virtues, and a peculiar significance lies hidden under this holy covering of the immaculate virginity of Maria, who, as her son is the almond-kernel, is naturally sung as the almond-flower. That is the character of the medieval poetry which we call Romantic.
Classic art had only to represent the finite or determined, and its forms could be one and the same with the idea of the artist. Romantic art had to set forth, or rather signify, the infinite and purely spiritual, and it took refuge in a system of traditional, or rather of parabolistic symbols, as Christ himself had sought to render clear his spiritualistic ideas by all kinds of beautiful parables. Hence the mystical, problematic, marvelous, and transcendental in the artwork of the Middle Ages, in which fantasy makes her most desperate efforts to depict the purely spiritual by means of sensible images, and invents colossal follies, piling Pelion on Ossa and Parsifal on Titurel to attain to heaven.
Among other races where poetry attempted to display the infinite, and where monstrous fancies appeared, as, for instance, among the Scandinavians and Indians, we find poems which, being romantic, are given that classification.
We cannot say much as to the music of the Middle Ages, for original documents, which might have served for our guidance, are wanting. It was not till late in the sixteenth century that the masterpieces of Catholic church music, which cannot be too highly praised, appeared. These express in the most exquisite manner pure Christian spirituality. The recitative arts, which are spiritual from their very nature, could indeed flourish fairly in Christianity, yet it was less favorable to those of design, for as these had to represent the victory of mind over matter, and yet must use matter as the means wherewith to work, they had to solve a problem against Nature. Hence we find in sculpture and painting those revolting subjects—martyrdoms, crucifixions, dying saints, and the flesh crushed in every form. Such themes were martyrdom for sculpture; and when I contemplate those distorted images in which Christian asceticism and renunciation of the senses are expressed by distorted, pious heads, long thin arms, starveling legs, and awkwardly fitting garments, I feel an indescribable compassion for the artists of that time. The painters were indeed more favored, for the material for their work, because of its susceptivity to varied play of color, did not antagonize spirituality so obstinately as the material of the sculptors, and yet they were obliged to load the sighing canvas with the most repulsive forms of suffering. In truth, when we regard many galleries which contain nothing but scenes of bloodshed, scourging, and beheading, one might suppose that the old masters had painted for the collection of an executioner.
But human genius can transform and glorify even the unnatural; many painters solved this problem of making what was revolting beautiful and elevating—the Italians, especially, succeeding in paying tribute to beauty at the expense of spirituality, and in rising to that ideality which attained perfection in so many pictures of the Madonna. As regards this subject the Catholic clergy always made some concession to the physical. This image of immaculate beauty which is glorified by maternal love and suffering had the privilege of being made famous by poets and painters, and adorned with all charms of the sense, for it was a magnet which could attract the multitude to the lap of Christianity. Madonna Maria was the beautiful dame du comptoir of the Catholic Church, who, with her beautiful eyes, attracted and held fast its customers, especially the barbarians of the North.
Architecture had in the Middle Ages the same character as the other arts, as indeed all the manifestations of life then harmonized so marvelously with one another. The tendency to parable shows itself here, as in poetry. When we now enter a Gothic cathedral, we hardly suspect the esoteric sense of its stone symbolism; only a general impression pierces our soul; we realize an elevation of feeling and mortification of the flesh. The interior is a hollow cross, and we wander among the instruments of martyrdom itself; the variegated windows cast on us red and green light, like blood and corruption; funeral songs wail about us; under our feet are mortuary tablets and decay; and the soul soars with the colossal columns to a giddy height, tearing itself with pain from the body, which falls like a weary, worn-out garment to the ground. But when we behold the exteriors of these Gothic cathedrals, these enormous buildings which are wrought so aërially, so finely, delicately, transparently, cut as it were into such open work that one might take them for Brabant lace in marble, then we feel truly the power of that age which could so master stone itself that it seems spectrally transfused with spiritual life, and thus even the hardest material declares Christian spirituality.
