many citizens, giving them horses and all knightly accoutrements very nobly, and then he came into England, and set the heart of his said brother in a golden cup upon a pillar at the head of London Bridge over the river Thames, to keep the English in mind of the outrage sustained. For the which thing, Edward, after he became king, was never friendly towards King Charles, nor to his folk. After like manner, Philip, king of France, departed with his folk, and came and dwelt many days in Florence; and when he was come into France, he buried the body of the good King Louis, his father, with great honour, and had himself crowned with great solemnity at Rheims.

The aforesaid Pope, the year after his coronation, set forth with his court from Rome to go to Lyons-on-Rhone to the council which he had summoned, and he entered into Florence with his cardinals, and with King Charles, and with the Emperor Baldwin of Constantinople, which was of the lineage of the chief house of Flanders. This Baldwin was son of Henry, the brother of the first Baldwin, which conquered Constantinople with the Venetians, as we before made mention. And with the Pope, and with King Charles, there came to Florence many other lords and barons, on the 18th day of June, in the year of Christ 1273, and were received with honour by the Florentines. And the situation of Florence being pleasing to the Pope, by reason of the convenience of the water, and the pure air, and that the court found much comfort there, he purposed to abide there, and pass the summer in Florence. And finding that this good city of Florence was being destroyed by reason of the parties (the Ghibellines being now in exile), he determined that they should return to Florence, and should make peace
