The martyrdom of Thomas Becket served his cause better than his continuance in life could have done. Even if his murderers foolishly thought to serve the king by their deed, Henry himself was under no delusion as to its effect. He was thunderstruck at the news, and, in a frenzy of horror which was no doubt genuine, as well as to mark his repudiation of all share in the deed, he fasted and shut himself from communication with the court for days. But the public opinion of Europe would not acquit Henry of the guilt. Letters poured in upon the pope denouncing him and demanding his punishment. The interdict of his Norman dominions which had been threatened was proclaimed by the Archbishop of Sens, but suspended again by an appeal to the pope. Events moved slowly in the twelfth century, and before the pope could take any active steps in the case, an embassy which left Normandy almost immediately had time to reach him and to promise on the part of the king his complete submission to whatever the pope should decree after examination of the facts. Immediate punishment of any severity was thus avoided, and the embassy of two cardinals to Normandy which the pope announced could act only after some delay. In the meanwhile in England Thomas the archbishop was being rapidly transformed into Thomas the saint. Miracles were reported almost at once, and the legend of his saintship took its rise and began to throw a new light over the events of his earlier life. The preparation of his body for the grave had revealed his secret asceticism,--the hair garments next his skin and long unchanged. The people believed him to be a true martyr, and his popular canonization preceded by some time the official, though this followed with unusual quickness even for the middle ages. It was pronounced by the pope in whose reign he had died on February 21, 1173. For generations he remained the favourite saint of England, and his popularity in foreign lands is surprising, though it must be remembered that he was a great and most conspicuous martyr of the official Church, of the new Hildebrandine Church, of the spirit and ideas which were by that date everywhere in command.
