When the Master and the people of Lisbon saw that the King of Castile had departed with his people and had raised the siege at the moment of the city's greatest tribulation, which was the dearth of provisions, as there were none to be had, their joy at his departure was such that it is not possible to express it in writing. They gave many thanks to the Lord God, Who had taken mercy on them in that way.

Then they went out of the city to see the area of the siege camp that had already been burned, and found many sick people in the Convent of Santos that we have mentioned. They treated them with charitable compassion, even though they were their enemies.

The following day, they organised a great and devout procession, in which everyone went barefoot to the Monastery of the Trindade which is within the city wall. The Most Honourable João Escudeiro, who was then bishop of the city, set out barefoot from the cathedral church of his see, in pontificals, with the Host in his hands, as decently and honourably as could be, accompanied by a great number of regular and secular clergy, and also by the Master with all the other people.

When they had all arrived at the monastery, and devoutly said their prayers, a great and notable preacher, Master Rodrigo de Sintra of the Order of St Francis, who was well versed in theology, began to preach. He gave a long and solemn sermon, fully illustrated with texts from the Holy Scriptures, which he brought to bear to his purpose in a very learned manner. We cannot give more than the broad lines which it followed, according to what some have written very briefly, which was as follows.

At the beginning of his sermon, he took as his theme ‘Misericordiam fecit nobiscum’, repeating it in the vernacular, ‘The Lord has been most merciful to us’. Next, he expounded what mercy and pity were, and how mercy proceeded from the laws of nature, and lay in man's duty to relieve his neighbour from the misery he suffers, and how all the perfection of the Christian religion lay in mercy and pity.
