It is a harsh thing to say, but one which all sociology teaches us, that as there exists no sensual relation which cannot produce for its ennoblement a certain amount of passion, so also does there exist no passion (and Phaedrus is there to prove it) so vile and loathsome as to be unable to weave about itself a glamour of ideal sentiment. The poets of the Middle Ages strove after the criminal possession of another man's wife. This, however veiled with fine and delicate poetic expressions, is the thing for which they wait and sigh and implore; this is the reward, the supremely honouring and almost sanctifying reward which the lady cannot refuse to the knight who has faithfully and humbly served her. The whole bulk of the love lyrics of the early Middle Ages are there to prove it; and if the allusions in them are not sufficiently clear, those who would be enlightened may study the discussions of the allegorical persons even in the English (and later) version of Guillaume de Lorris' "Roman de la Rose;" and turn to what, were it in langue d'oc, we should call a tenso of Guillaume li Viniers among Mätzner's "Altfranzösische Lieder-dichter." The catastrophe of Ulrich von Liechtenstein's "Frowendienst," where the lady, the "virtuous," the "pure," as he is pleased to call her, after making him cut off his finger, dress in leper's clothes, chop off part of his upper lip, and go through the most marvellous Quixotic antics dressed in satin and pearls and false hair as Queen Venus, and jousting in this costume with every knight between Venice and Styria, all for her honour and glory; pulls the gallant in a basket up to her window, and then lets him drop down into the moat which is no better than a sewer; this grotesque and tragically resented end of Ulrich's first love service speaks volumes on the point. The stones in Nostradamus' "Lives of the Troubadours," the incidents in Gottfried's "Tristan und Isolde," nay, the adventures even in our expunged English "Morte d'Arthur," relating to the birth of Sir Galahad, are as explicit as anything in Brantôme or the Queen of Navarre; the most delicate love songs of Provence and Germany are cobwebs spun round Decameronian situations. And all this is permitted, admitted, sanctioned by feudal society even as the cecisbeos of the noble Italian ladies were sanctioned by the society of the seventeenth and eighteenth centuries. In the mediaeval castle, where, as we have seen, the lady, separated from her own sex, is surrounded by a swarm of young men without a chance of marriage, and bound to make themselves agreeable to the wife of a military superior; the woman soon ceases to be the exclusive property of her husband, and the husband speedily discovers that the majority, hence public ridicule, are against any attempt at monopolizing her. Thus adultery becomes, as we have seen, accepted as an institution under the name of service; and, like all other social institutions, developes a morality of its own—a morality within immorality, of faithfulness within infidelity. The lady must be true to her knight, and the knight must be true to his lady: the Courts of Love solemnly banish from society any woman who is known to have more than one lover. Faithfulness is the first and most essential virtue of mediaeval love; a virtue unknown to the erotic poets of Antiquity, and which modern times have inherited from the Middle Ages as a requisite, even (as the reproaches of poets of the Alfred de Musset school teach us) in the most completely illicit love. Tristram and Launcelot, the two paragons of knighthood, are inviolably constant to their mistress: the husband may and must be deceived, but not the wife who helps to deceive him. Yseult of Brittany and Elaine, the mother of Galahad, do not succeed in breaking the vows made to Yseult the Fair and to Queen Guenevere. The beautiful lady in the hawthorn alba "a son cor en amar lejalmens." But this loyal loving is for the knight who is warned to depart, certainly not for the husband, the gilos, in whose despite ("Bels dous amios, baizem nos eu e vos—Aval els pratzon chantols auzellos—Tot O fassam en despeit del gilos") they are meeting. The ladies of the minnesingers are "pure," "good," "faithful" (and each and all are pure, good, and faithful, as long as they do not resist) from the point of view of the lover, not of the husband, if indeed a husband be permitted to have any point of view at all. And as fidelity is the essential virtue in these adulterous connections, so infidelity is the greatest crime that a woman (and even a man) can commit, the greatest misfortune which fate can send to an unhappy knight. That he leaves a faithful mistress behind him is the one hope of the knight who, taking the cross, departs to meet the scimitars of Saladin's followers, the fevers, the plagues, the many miserable deaths of the unknown East. "If any lady be unfaithful," says Quienes de Béthune, "she will have to be unfaithful with some base wretch."

Et les dames ki castement vivront
Se loiauté font a ceus qui iront;
Et seles font par mal conseil folaje,
A lasques gens et mauvais le feront,
Car tout li bon iront en cest voiage.

"I have taken the cross on account of my sins," sings Albrecht von Johansdorf, one of the most earnest of the minnesingers; "now let God help, till my return, the woman who has great sorrow on my account, in order that I may find her possessed of her honour; let Him grant me this prayer. But if she change her life (i.e., take to bad courses), then may God forbid my ever returning." The lady is bound (the Courts of Love decide this point of honour) to reward her faithful lover. "A knight," says a lady, in an anonymous German song published by Bartsch, "has served me according to my will. Before too much time elapse, I must reward him; nay, if all the world were to object, he must have his way with me" ("und waerez al der Werlte leit, so muoz sîn wille an mir ergän"). But, on the other hand, the favoured knight is bound to protect his lady's good fame.

Se jai mamie en tel point mis,
Que tout motroit (m'octroit) sans esformer,
Tant doi je miex sonnor gaiter—

thus one of the interlocutors in a French jeu-parti, published by Mätzner; a rule which, if we may judge from the behaviour of Tristram and Launcelot, and from the last remnants of mediaeval love lore in modern French novels, means simply that the more completely a man has induced a woman to deceive her husband, the more stoutly is he bound to deny, with lies, rows, and blows, that she has ever done anything of the sort. Here, then, we find established, as a very fundamental necessity of this socially recognized adultery, a reciprocity of fidelity between lover and mistress which Antiquity never dreamed of even between husband and wife (Agamemnon has a perfect right to Briseis or Chryseis, but Clytaemnestra has no right to Aegisthus); and which indeed could scarcely arise as a moral obligation except where the woman was not bound to love the man (which the wife is) and where her behaviour towards him depended wholly upon her pleasure, that is to say, upon her satisfaction with his behaviour towards her. This, which seems to us so obvious, and of which every day furnishes us an example in the relations of the modern suitor and his hoped-for wife, could not, at a time when women were married by family arrangement, arise except as a result of illegitimate love. Horrible as it seems, the more we examine into this subject of mediaeval love, the more shall we see that our whole code of Grandisonian chivalry between lovers who intend marriage is derived from the practice of the Launcelots and Gueneveres, not from that of the married people (we may remember the manner in which Gunther woos his wife Brunhilt in the Nibelungenlied) of former ages; nay, the more we shall have to recognize that the very feeling which constitutes the virtuous love of modern poets is derived from the illegitimate loves of the Middle Ages.

Let us examine what are the habits of feeling and thinking which grow out of this reciprocal fidelity due to the absence of all one-sided legal pressure in this illegitimate, but socially legitimated, love of the early Middle Ages; which are added on to it by the very necessities of illicit connection. The lover, having no right to the favours of his mistress, is obliged, in order to win and to keep them, to please her by humility, fidelity, and such knightly qualities as are the ideal plumage of a man: he must bring home to her, by showing the world her colours victorious in serious warfare, in the scarcely less dangerous play of tournaments, and by making her beauty and virtues more illustrious in his song than are those of other women in the songs of their lovers—he must bring home to her that she has a more worthy servant than her rivals; he must determine her to select him and to adhere to her selection. Now mediaeval husbands select their wives, instead of being selected; and once the woman and the dowry are in their hands, trouble themselves but little whether they are approved of or not. On the other hand, the mistress appears to her lover invested with imaginative, ideal advantages such as cannot surround her in the eyes of her husband: she is, in nearly every case, his superior in station and the desired of many beholders; she is bound to him by no tie which may grow prosaic and wearisome; she appears to him in no domestic capacity, can never descend to be the female drudge; her possession is prevented from growing stale, her personality from becoming commonplace, by the difficulty, rareness, mystery, adventure, danger, which even in the days of Courts of Love attach to illicit amours; above all, being for this man neither the housewife nor the mother, she remains essentially and continually the mistress, the beloved. Similarly the relations between the knight and the lady, untroubled by domestic worries, pecuniary difficulties, and squabbles about children, remain, exist merely as love relations, relations of people whose highest and sole desire is to please one another. Moreover, and this is an important consideration, the lady, who is a mere inexperienced, immature girl when she first meets her husband, is a mature woman, with character and passions developed by the independence of conjugal and social life. When she meets her lover, whatever power or dignity of character she may possess is ripe; whatever intensity of aspiration and passion may be latent is ready to come forth; for the first time there is equality in love. Equality? Ah, no. This woman who is the wife of his feudal superior, this woman surrounded by all the state of feudal sovereignty, this woman who, however young, has already known so much of life, this woman whose love is a free, gift of grace to the obscure, trembling vassal who has a right not even to be noticed; this lady of mediaeval love must always remain immeasurably above her lover. And, in the long day-dreams while watching her, as he thinks unseen, while singing of her, as he thinks unheard, there cluster round her figure, mistily seen in his fancy, those vague and-mystic splendours which surround the new sovereign of the Middle Ages, the Queen of Heaven; there mingles in the half-terrified raptures of the first kind glance, the first encouraging word, the ineffable passion stored up in the Christian's heart for the immortal beings who, in the days of Bernard and Francis, descend cloud-like on earth and fill the cells of the saints with unendurable glory.

And thus, out of the baseness of habitual adultery, arises incense-like, in the early mediaeval poetry, a new kind of love—subtler, more imaginative, more passionate, a love of the fancy and the heart, a love stimulating to the perfection of the individual as is any religion; nay, a religion, and one appealing more completely to the complete man, flesh and soul, than even the mystical beliefs of the Middle Ages. And as, in the fantastic song of Ritter Tannhäuser, whose liege lady, so legend tells, was Dame Venus herself, the lady bids the knight go forth and fetch her green water which has washed the setting sun, salamanders snatched from the flame, the stars out of heaven; so would it seem as if this new power in the world, this poetically worshipped woman, had sent forth mankind to seek wonderful new virtues, never before seen on earth. Nay, rather, as the snowflakes became green leaves, the frost blossoms red and blue flowers, the winter wind a spring-scented breeze, when Bernard de Ventadorn was greeted by his mistress; so also does it seem as if, at the first greeting of the world by this new love, the mediaeval winter had turned to summer, and there had budded forth and flowered a new ideal of manly virtue, a new ideal of womanly grace.

But evil is evil, and evil is its fruit. Out of circumstances hitherto unknown, circumstances come about for the first time owing to the necessities of illegitimate passion, have arisen certain new and nobler characters of sexual love, certain new and beautiful conceptions of manly and womanly nature. The circumstances to which these are owed are pure in themselves, they are circumstances which in more modern times have characterized the perfectly legitimate passion of lovers held asunder by no social law, but by mere accidental barriers—from Romeo and Juliet to the Master of Ravenswood and Lucy Ashton; and pure so far have been the spiritual results. But these circumstances were due, In the early Middle Ages, to the fact of adultery; and to the new ideal of love has clung, even in its purity, in its superior nobility, an element of corruption as unknown to gross and corrupt Antiquity as was the delicacy and nobility of mediaeval love. The most poetical and pathetic of all mediaeval love stories, the very incarnation of all that is most lyric at once and most tragic in the new kind of passion, is the story, told and retold by a score of poets and prose writers, of the loves of Yseult of Ireland and of Sir Tristram who, as the knight was bringing the princess to his uncle and her affianced, King Mark of Cornwall drank together by a fatal mistake a philter which made all such as partook of it in common inseparable lovers even unto death. Every one knows the result r: how Yseult came to her husband already the paramour of Tristram; how Brangwaine, her damsel, feeling that this unhallowed passion was due to her having left-within reach the potion intended for the King and Queen of Cornwall, devoted herself, at the price of her maidenhood, to connive in the amours of the lovers whom she had made; how King Mark was deceived, and doubted, and was deceived again; how Tristram fled to Brittany, but how, despite his seeming marriage with another and equally lovely Yseult, he remained faithful to the Queen of Cornwall. One version tells that Mark slew his nephew while he sat harping to Queen Yseult; another that Tristram died of grief because his scorned though wedded wife told him that the white-sailed ship, bearing his mistress to meet him, bore the black sail which meant that she was not on board; but all versions, I think, agree in ending with the fact, that the briar-rose growing on the tomb of the one, slowly trailed its flowers and thorns along till it had reached also the grave of the other, and knit together, as love had knit together with its sweet blossoms and sharp spines, the two fated lovers. The Middle Ages were enthralled by this tale; but they were also, occasionally, a little shocked by it. Poets and prose writers tampered every now and then with incidents and characters, seeking to make it appear that, owing to the substitution of the waiting-maid, and the neglect of the wedded princess of Brittany, Yseult had never belonged to any man save Tristram, nor Tristram to any woman save Yseult; or that King Mark had sent his nephew to woo the Irish queen's daughter merely in hopes of his perishing in the attempt, and that his whole subsequent conduct was due to a mere unnatural hatred of a better knight than himself; touching up here and there with a view to justifying and excusing to some degree the long series of deceits which constituted the whole story. Thus the more timid and less gifted. But when, in the very first years (1210) of the thirteenth century, the greatest mediaeval poet that preceded Dante, the greatest German poet that preceded Goethe, Meister Gottfried von Strassburg, took in hand the old threadbare story of "Tristan und Isolde," he despised all alterations of this sort, and accepted the original tale in its complete crudeness.

For, consciously or unconsciously, Gottfried had conceived this story as a thing wholly unknown in his time, and no longer subject to any of those necessities of constant re-arrangement which tormented mediaeval poets: he had conceived it not as a tale, but as a novel. Gottfried himself was probably but little aware of what he was doing; the poem that he was writing probably fell for him into the very same category as the poems of other men; but to us, with our experience of so many different forms of narrative, it must be evident that "Tristan und Isolde" is a new departure, inasmuch as it is not the story of deeds and the people who did them, like the true epic from Homer to the Nibelungen; nor the story of people and the adventures which happened to them, like all romance poetry from "Palemon and Arcite," to the "Orlando Furioso;" but, on the contrary, the story of the psychological relations, the gradual metamorphosis of soul by soul, between two persons. The long introductory story of Tristram's youth must not mislead us, nor all the minute narrations of the killing of dragons and the drinking of love philters: Gottfried, we must remember, was certainly no deliberate innovator, and these thing's are the mere inevitable externalities of mediaeval poetry, preserved with dull slavish care by the re-writer of a well-known tale, but enclosing in reality something essentially and startlingly modern: the history of a passion and of the spiritual changes which it brings about in those who are its victims.

To meet again this purely psychological interest we must skip the whole rest of the Middle Ages, nay, skip even the great period of dramatic literature, not stopping till we come to the end of the seventeenth and beginning of the eighteenth century, to the "Princesse de Clèves," to "Clarissa Harlowe," nay, really, to "The Nouvelle Heloise." For even in Shakespeare there is always interest and importance in the action and reaction of subsidiary characters, in the event, in the accidental; there is intrigue, chance, misunderstanding, fate—active agencies of which Othello and Hamlet, King Lear and Romeo, are helpless victims; there is, even in this psychological English drama of the Elizabethans, fate in the shape of Iago, in the shape of the Ghost, in the shape of the brothers of Webster's duchess; fate in the shape of a ring, a letter, a drug, but fate always. And in this "Tristan und Isolde" of Gottfried von Strassburg is there not fate also in the love potion intended for King Mark, and given by the mistake of Brangwaine to Mark's bride and his nephew? To this objection, which will naturally occur to any reader who is not acquainted with the poem of Gottfried, I simply answer, there is not. The love potion there is, but it does not play the same part as do, for instance, the drugs of Friar Laurence and his intercepted letter. Suppose the friar's narcotic to have been less enduring in its action, or his message to have reached in safety, why then Juliet would have been awake instead of asleep, or Romeo would not have supposed her to be dead, and instead of the suicide of the two lovers, we should have had the successful carying off of Juliet by Romeo. Not so with Gottfried. The philter is there, and a great deal is talked about it; but it is merely one of the old, threadbare trappings of the original story, which he has been too lazy to suppress; it is merely, for the reader, the allegorical signal for an outburst of passion which all our subsequent knowledge of Tristram and Yseult shows us to be absolutely inevitable. In Gottfried's poem, the drinking of the potion signifies merely that all the rambling, mediaeval prelude, not to be distinguished from the stories of "Morte d'Arthur," and of half the romances of the Middle Ages, has come to a close and may be forgotten; and that the real work of the great poet, the real, matchless tragedy of the four actors—Tristram, Yseult, Mark, and Brangwaine—has begun.
