During an interval of banishment, following a more than usually cruel murder, he had visited Germany, and had met at young Henry's court with many people to whom Pope Gregory was obnoxious, from Gottfried the Hunchback, the husband of the Countess Matilda, to the young king himself. Whether what followed was the result of any conspiracy, however, or if it was an outburst of mad vengeance on the part of Cencius himself, or the mere calculating impulse of a freebooter to secure a good ransom, is not known. A conspiracy, with Godfrey at the head of it, not without support from Henry, and the knowledge at least of the Archbishop of Ravenna and Robert Guiscard, all deeply irritated by the Pope's recent proceedings, was of course the favourite idea at the time. But no clear explanation of motives has ever been attained, and only the facts are known. On Christmas-eve it was the habit of the Popes to celebrate a midnight mass in the great basilica of Sta. Maria Maggiore in what was then a lonely and dangerous neighbourhood, though not very far from the Lateran Church and palace. It was usually the occasion of a great concourse from all parts of the city, attracted by the always popular midnight celebration. But on Christmas-eve of the year 1076 (Muratori says 1075) a great storm burst over the city as the hour approached for the ceremony. Torrents of rain, almost tropical in violence, as rain so often is in Rome, poured down from the blackness of the skies, extinguishing even the torches by which the Pope and his diminished procession made their way to the great church, blazing out cheerfully with all its lighted windows into the night. Besides the priests only a very small number of the people followed, and there was no such murmur and rustle of sympathy and warmth of heart as such an assembly generally calls forth. But the great altar was decorated for Christmas, and the Pope attired in his robes, and everything shining with light and brightness within, though the storm raged without. The mass was almost over, Gregory and the priests had communicated, the faithful company assembled were receiving their humbler share of the sacred feast, and in a few minutes the office would have been completed, when suddenly the church was filled with noise and clamour and armed men. There was no one to defend the priests at the altar, even had it been possible in the suddenness of the assault to do so. Cencius's band was composed of ruffians from every region, united only in their lawlessness and crime; they seized the Pope at the altar, one of them wounding him slightly in the forehead. It is said that he neither asked for mercy nor uttered a complaint, nor even an expostulation, but permitted himself without a word to be dragged out of the church, stripped of his robes, placed on a horse behind one of the troopers, and carried off into the night not knowing where.
