On the threshold of the second stage of the erotic life stands Christianity, which, in sharp contrast to antiquity and to the classical period, sought the centre and climax of life in the soul. The founder of the "religion of love" _discovered_ the individual, and by so doing laid the foundation for that metaphysical love which found its most striking expression in the deification of woman and the cult of the Virgin Mary. How this change of mental attitude was brought about is worked out in a brilliant chapter, entitled "The Birth of Europe." The revivifying influence of Christ's preaching and personality was stifled after the first centuries by the rigid dogma and formalism which had altered his doctrine almost past recognition. The Church was building up its political structure and tolerated no rival. Art, literature, music, all the enthusiasm and profound thought of which the human mind is capable, were pressed into her service. Independent thought was heresy, and the death of every heretic became a new fetter which bound the intellect of man. But about the year 1100, when the mighty edifice was complete, and 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. "She shines on us as God shines on his angels," 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. "I cannot sin when I am in her mind," 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: Love makes good men better, And the worst man good.
