Leaving matters in this train, the Cardinal returned to Rome; while, according to Florentine court authorities, Bianca's pregnancy continued to proceed towards its conclusion in the most satisfactory manner. The Grand Duke's conduct during this time makes it very difficult to judge whether he sincerely believed that the Grand Duchess was about to give him an heir at last, or whether he was all the time contemplating a second performance of the farce which took place at the birth of Don Antonio, of which he had been at first the dupe, but in which he had become afterwards the accomplice;—or, finally, whether both these suppositions were true, so that, if his sincere hopes of a child by Bianca should be disappointed, he was ready to supply the desideratum by a fraud. He lived in a perpetual agitation of mind, and showed a degree of irritation and annoyance at the notice which the Cardinal's manœuvres had drawn upon the doings at the Pitti, that, joined to his former conduct, is suspicious. On the other hand, he acted in many respects as if he were sincere in the matter. It is also to be observed that, possibly enough, Bianca may have been sincere on this occasion; especially as we know she never abandoned her hopes, and was always trying new means to bring about her desire. She seems to have professed to be very doubtful on the subject to the last. But some writers insinuate, that while she expressed doubts to the Cardinal, she spoke in an entirely different manner to her husband. Meantime, the daily reports in Florence were the amusement of the citizens, and the bulletins made Francesco and his hopes the laughing–stock of all Italy. Francesco had ordered that all the chiefs of the different magistracies, the Archbishop of Florence, and the Bishop Abbioso, should be present at the birth. And this, it must be owned, looks very much as if he were sincere in his expectations, either duped by Bianca, as in the former case, or partaking in her error. He also wrote to the Cardinal, though in very ungracious terms, to invite his presence at Florence on the occasion. "Since the promotion (of Cardinals) is over," he wrote, "and there is nothing further to detain your Eminence in Rome, I will not neglect to tell you that the Grand Duchess advances in her pregnancy visibly from day to day, and with greater hope of a fortunate issue than ever. You can therefore come, if it so please you, and observe all that takes place. You have still the time to do so, and cannot now say afterwards, that you were left in ignorance upon the subject."[214] But in answer to this hostilely worded invitation, and to a second letter written in the same tone, the Cardinal replied by an angry letter, absolutely refusing to come or to send any one to Florence on his behalf, "as he had no wish to see or hear more in the matter than the Grand Duke did himself, seeing that his Highness was the person chiefly interested."
