So there was a social life at this time and place which was filled with refinement and courtesy, and it centred about the ladies of the courts. Each troubadour, and many of them were brave knights as well, sought to sing the praises of his lady, devote himself to her service, and do her bidding in all things great and small. There was a proverb in Provence, it is true, which declared that "A man's shadow is worth a hundred women," and another saying, "Water spoils wine, carts spoil roads, and women spoil men"; but, in spite of all this, devotion to women was developed to a most unusual degree, and there was even an attempt made to fix the nature of such soft bondage by rule and regulation. Southern natures were so impetuous that some checks upon the practice of this chivalric love seemed to be imperative, as thinking people felt that love should not go unbridled. Justin H. Smith, who has written so entertainingly of the _Troubadours at Home_, says that it was their expedient to make love a "science and an art. Rules were devised, and passion was to be bound with a rigid etiquette like that of chivalry or social intercourse. It was to be mainly an affair of sentiment and honor, not wholly Platonic to be sure, but thoroughly desensualized. Four stages were marked off in the lover's progress: first, he adored for a season without venturing to confess it; secondly, he adored as a mere suppliant; thirdly, he adored as one who knew that the lady was not indifferent; and finally, he became the accepted lover, that is to say, the chosen servitor and vassal of his lady, her special knight."
