The helpful and joy-bestowing power of good works, which the Protestants denied, had thus become very evident to her; for since she had clasped the sufferer's hand an indescribable sense of happiness had taken possession of her, while the knight began to improve. The news had reached her just before this, the Emperor's, arrival, had made her happy, and, in spite of her evil conscience, had put her in a very cheerful mood. But now this beautiful evening had become the saddest one of her whole life. Fresh tears, and the other means of conciliation inspired by her loving heart, then induced the angry lover to forgive her. Barbara felt this as a great piece of good fortune, and made every effort to curb the refractory temper which, hitherto, had found nothing less welcome than humble submission. Day after day since that evening the confessor had been informed that nothing interrupted the concord of the lovers, and that Barbara often prayed very fervently in the private chapel. This pleased the almoner, and when Cassian told him that, on the evening after the quarrel, the Emperor had again come to the castle to remain a long time, he rejoiced. To Barbara this visit had been a true heavenly blessing, but though Charles showed himself sufficiently loving, she felt, even during the succeeding visits, that since that fateful episode something difficult to describe or explain had rested like a gloomy shadow on the Emperor's joyous confidence. This change in her lover could scarcely be due to her, for she had honestly endeavoured to avoid everything which could anger him. How should she have suspected that the great student of human nature to whom she had given her heart perceived the restraint which she imposed upon herself in every interview with him, and that the moderation to which she submitted from love robbed her of a portion of the charm her gay unconcern had exerted upon him? Charles suspiciously attributed this change in the disposition of the woman he loved sometimes to one cause, sometimes to another; and when he showed her that he missed something in her which had been dear to him, she thought it a new token of his dissatisfaction, and increased the restraint which she placed upon herself. If the gout again attacked him or the pressure of business, which at that time constantly made more and more imperious demands upon the Emperor Charles, detained him from her on one or another evening, torturing anxiety assailed her, and she had no sleep all night. Besides, the marquise did not cease to press her with entreaties and expostulations, and Frau Lerch constantly urged Barbara to profit by the favour of such a lover. She ought to think of the future, and indemnify herself with estates and titles for the sad fate awaiting her if his Majesty wearied of her love.
