the pope and his bishops looked down upon kings and emperors and counted them their vassals, when the barbaric peoples which made up the population of Europe had been sufficiently schooled and educated in the new direction, a longing for something new, a yearning for art, for poetry, for beauty, began to stir the hearts of men and women. It found expression in the ideal of chivalry, the Holy Sepulchre and the Holy Grail, and suddenly love, bursting out in a brilliant flame, shed its radiance on the sordid relationship which had hitherto existed between the sexes, and transfigured it. Woman, the despised, to whom at the Council of Macon a soul had been denied, all at once became a queen, a goddess. The drudge, the patiently suffering wife, were things of the past. A new ideal had been set up and men worshipped it with bended knees.

sang Guinicelli.

It was in a small country in the South of France, in Provence, that the new spirit was born. The troubadours, wandering from castle to castle, sang the praise of love, genuine love, the earlier ones without admixture either of speculation or metaphysic. The dogma that pure love was its own reward inasmuch as it made men perfect, was framed later on.

wrote Guirot Riquier, and Dante, in the "Vita Nuova," calls his beloved mistress "the destroyer of all evil and the queen of all virtues." The monk Matfre Ermengau, who wrote a text-book on love, says:

The later troubadours drew a much sharper distinction between spiritual and sensual love. The latter was regarded as degrading and base (at least in principle) and woe to the man who held, or rather, avowed, another opinion. His reward was the contempt of every man and woman of culture. "I ask no more of my mistress than that she should suffer me to serve her," protested Bernart de Ventadour.

It goes without saying that, in spite of this high ideal, sensuality flourished undiminished, and a troubadour who loudly sang the praise of chastity and blatantly professed his entire disinterestedness in the service of his mistress, did not see the least inconsequence in carrying on a dozen intrigues at the same time with other women. Sordello, one of the best known poets of this period, was charged by a contemporary with having changed his mistress over a hundred times, and he himself, impudently bragging, proclaims that

Another poet, Count Rambaut III., of Orange, recommended to his fellow-men as the surest way of winning a woman's favour, "to break her nose with a blow of the fist." "I myself," he continued, "treat all women with tenderness and courtesy, but then—I am considered a fool."

As may be expected, sublimated, metaphysical love was not without its caricatures and eccentricities. One of the most grotesque figures of the period of the troubadours was Ulrich von Lichtenstein, a German knight. As a page, we are told, he drank the water in which his mistress had washed her hands. Later on he had his upper lip amputated because it displeased his lady-love, and on another occasion he cut off one of his fingers, had it set in gold and used as a clasp on a volume of his poems which he sent as a present to his inamorata.

At the famous Courts of Love, the most extraordinary questions were seriously discussed and decided. A favourite subject for debate was the relationship between love and marriage, and some of the decisions which have been preserved for us prove without a doubt that those two great factors in the emotional life were considered irreconcilable. At the Court of the Viscountess Ermengarde of Narbonne, the question whether the love between lovers was greater than the love between husband and wife was settled as follows: "Nature and custom have erected an insuperable barrier between conjugal affection and the love which unites two lovers. It would be absurd to draw comparisons between two things which have neither resemblance nor connection."

The contrast between the new, spiritualised love and the older, sexual, instinct created that dualism so characteristic of the whole mediaeval period. Sexuality and love were felt as two inimical forces, the fusion of which was beyond the range of possibility. While on the one hand woman was worshipped as a divine being, before whom all desire must be silenced, she was on the other hand stigmatised as the devil's tool, a power which turned men away from his higher mission and jeopardised the salvation of his soul. Wagner portrayed this dualism perfectly in Tannhauser. "A man of the Middle Ages," says Lucka, "would have recognised in this magnificent work the tragedy of his soul."

It was but a small step from the worship of a beloved mistress to the cult of the Virgin Mary. The Church, hostile at first, finally acquiesced, and "through her official acknowledgment of a female deity, open enmity between the religion of the Church and the religion of woman was avoided." A woman, that is to say, the Virgin Mary, had stepped between God and humanity as mediator, intercessor and saviour.

Both Dante, the inspired woman-worshipper of the Middle Ages, and the more modern Goethe, saw in metaphysical love the triumph over all things earthly. And far above either of these intellectual heroes looms the awe-inspiring figure of Michelangelo, the scoffer, to whom love came late in life; in his ecstatic adoration of Vittoria Colonna, the enthusiasm of Plato and the passion of Dante are blended in a more transcendent flame.

Sexual Mystics and the Brides of Christ present the darker aspect of metaphysical love. All the latter, including even Catherine of Siena (a clever politician who kept up a correspondence with the leading statesmen of her time), Marie of Oignies, and St. Teresa, are stigmatised as victims of hysteria and consigned to the domain of pathology.

While the first stage was characterised by the reign of unbridled sexual instinct, the second by the conflict between spiritual and sensual love, the third stage represents our modern conception, the blending of spiritual and sensual love, which is "not the differentiated sexual instinct, but a force embracing the psycho-physical entity of the beloved being without any consciousness of sexual desire." It shares with the purely metaphysical love the lover's longing to raise his mistress above him and glorify her without any ulterior object and desire. "In this stage there is no tyranny of man over woman, as in the sexual stage; no subjection of man to woman, as in the woman-worship of the Middle Ages; but complete equality of the sexes, a mutual give and take. If sexuality is infinite as matter, spiritual love eternal as the metaphysical ideal, then the synthesis is human and personal." The apotheosis of this perfect love Lucka finds in the Liebestod (the death of the lovers in the ecstasy of love), in Wagner's Tristan und Isolde.

An interesting chapter on erotic aberrations, the demoniacal and the obscene, completes the third part of the book.

There may be much in Lucka's theories which will rouse the scepticism of the monists; some of his deductions may appear to his readers a little strained, but no thinking man or woman can read his brilliant Conclusion without denying him the tribute of sincere admiration. In this last chapter he applies Haeckel's biogenetic law to
