"Things being thus arranged [writes the Pope] in order to secure, by the help of God, the peace of the Church and the union of the Kingdom, which we have so long desired, we are anxious to pursue our journey into your countries on the first occasion possible; for we desire you to know, as you may perceive from the written engagements, that everything is still in suspense, so that our arrival among you and the unanimity of your council is absolutely necessary to settle matters. Therefore be very attentive to continue as you have begun in faith and the love of justice, and understand that we have done nothing for the king, except to tell him that he might trust to us to help him in such things as may touch his salvation and his honour, with justice and with mercy, without putting our soul and his in peril." In the meantime Henry had enough to do in winning back again to his side the rebellious Lombards, who considered his submission to the Pope, however artificial, a desertion of their cause, and shut upon him the gates of their cities, which before his visit to Canossa had been thrown wide open. He had apparently, though only for a moment, lost them, while he had not regained the sympathies of Germany. There was nothing for it but a new apostasy, throwing over of his promises, and reassumption of the leadership of the schismatic party, which made the position of Gregory, surrounded by that angry sea of Lombard rebellion which beat against the base of his rocky stronghold, a very dangerous one. Through the whole spring of 1077 the Pope was more or less confined to the Castle of Canossa or other similar fortresses, under the vigilant care of Matilda; and it was from these strong places that he wrote a succession of remarkable letters to the nobles of Germany, who, strongly set upon the Diet in which the affairs of the kingdom were to be placed on a permanent footing, were proceeding to carry out their intention without waiting either for the presence of Gregory which they had invited, or Henry whose interests were at stake. Gregory did everything that was possible to delay the Diet until he could be present at it. He was anxious also to delay whatever great step might be in contemplation until the mind of the country was a little less anxious and disturbed: and he desired to be present, not only in the position of Arbitrator, but also to moderate with his counsels the excited spirits, and prevent if possible any great catastrophe.
