His plan, doubtless, was to let the divorce question drag on as long as possible, in the hope that Henry would tire of his new flame. First he persuaded the King to send fresh instructions to Knight, on the ground that the Pope would certainly not give him a dispensation to commit bigamy in order that he might marry Anne, and that it would be easier to obtain from the Pontiff a decree leaving the validity of the marriage with Katharine to the decision of the Legates in England, Wolsey and another Cardinal. Henry having once loosened the bridle, did not entirely return to his submission to Wolsey. Like most weak men, he found it easier to rebel against the absent than against those who faced him; but he was not, if he and Anne could prevent it, again going to put his neck under the Cardinal's yoke completely, and in a secret letter to Knight he ordered him to ask Clement for a dispensation couched in the curious terms already referred to, allowing him to marry again, even within the degrees of affinity, as soon as the union with Katharine was dissolved. Knight had found it impossible to get near the Pope in Rome, for the imperialists had been fully forewarned by this time; but at length Clement was partially released and went to Orvieto in December, whither Knight followed him before the new instructions came from England. Knight was no match for the subtle churchmen. Clement dared not, moreover, mortally offend the Emperor, whose men-at-arms still held Rome; and the dispensation that Knight sent so triumphantly to England giving the Legate's Court in London power to decide the validity of the King's marriage, had a clause slipped into it which destroyed its efficacy, because it left the final decision to the Pontiff after all.
