Although the most profound devotion was paid to woman in the abstract by the order, the Church sought to encourage perpetual celibacy, the seclusion of women, and the separation of the sexes. The clergy were forbidden to marry, and the idea seemed to prevail that it was impossible for men and women to mingle without being under the influence of lascivious ideas, and ready to carry them into practice as soon as opportunity offered. The attempt to organize society on such a basis had an inevitable tendency to produce demoralization. Its obvious result, instead of promoting chastity was to increase secret licentiousness and encourage prostitution. Even the voluntary vows of knights and troubadours were, in the end, as little observed as these ecclesiastical precepts. The profligacy of the Troubadours became open and undisguised, and the virtue of their mistresses naturally kept pace with their example. The knights who enlisted in the Crusades, with a large amount of zeal and but a small share of wealth, supported their retainers by robberies on the way, and the females who accompanied them acted as camp followers usually do. No institution which deals merely in external observances can restrain immorality in circumstances favorable to its development, and hence chivalry was forced to yield before more powerful influences. That it served its purpose in elevating the condition of woman, and in giving a better tone to society at large, it would be unjust to deny. Even when chivalry declined and ceased to inspire feats of knight-errantry, we find women, instead of falling back into the degrading position they had formerly occupied, employing themselves in intellectual pursuits, publishing books, mixing in public controversies, distinguishing themselves in the acquisition of languages, and even taking a leading part in the political affairs of the times. Among the women who acquired a historical notoriety by their position as royal mistresses, during the epoch comprised between the Norman conquest and the reign of Henry VIII., were the Fair Rosamond, concubine of Henry II., and Jane Shore, the mistress of Edward IV. The misfortunes, as well as the generous qualities of these fair sinners have thrown a sort of halo around them.
