It seems a strange descent from the dignity of this address, that the Pope should have gone on to comment upon a marvellous egg which it was said had been found near the church of St. Peter, with a strange design raised upon its surface--a buckler with the figure of a serpent underneath, struggling with bent head and wriggling body to get free. This had seemed, however, a wonderful portent to all Rome, and though his modern historians censure Gregory for having no doubt prepared the prodigy and taken a despicable advantage of it, there does not seem the slightest reason to suppose either that Gregory was guilty of this, or that he was so little a man of his time as not to be himself as much impressed by it as any one else there. Appearances of the kind, which an age on the lookout for portents can define, and make others see, are not wanting in any period. The crowd responded with cries that it was he, the father of the Church, who was supreme, and that the blasphemer should be cut off from the Church and from his throne. The sensation was not lessened when the full text[4] of Henry's letters, parts of which we have already quoted, was read out to the reassembled council next day. The words which named their Pope--their head who had been the providence and the guide of Rome for so many years--with contemptuous abuse as "the monk Hildebrand," must have stirred that assembly to its depths. The council with one voice demanded from Gregory the excommunication of the Emperor, and of the impious bishops, false to every vow, who had ventured to launch an anathema against the lawful head of the Church. The solemn sentence of excommunication was accordingly pronounced against Henry: his subjects were freed from their oath of allegiance, and his soul cut off from the Church which he had attempted to rend in twain. Excommunications had become so common in these days that the awe of the extraordinary ceremonial was much lessened: but it was no mere spiritual deprivation, as all were aware, but the most tremendous sentence which could be launched against a man not yet assured in his victories over his own rebellious tributaries, and whose throne depended upon the fidelity of powerful vassals, many of whom were much more impressed by the attitude of the Pope than by that of the king. Thus after so many preliminaries, treaties of peace and declarations of war, the great conflict between Pope and Emperor, between the Church and the State, began. The long feud which ran into every local channel, and rent every mediæval town asunder with the struggles of Guelfs and Ghibellines, thus originated amid events that shook the world. The Synod of Worms and the Council of Rome, with their sudden and extraordinary climax in the conference of Canossa, formed the first act in a drama played upon a larger stage and with more remarkable accompaniments than almost any other in the world.
