In winter he abode at Foggia, and in summer in the mountains, for the delights of the chase. And many other noteworthy things he caused to be made, as the castle of Prato, and the fortress of Samminiato, and many other things, as we shall make mention hereafter. And he had two sons by his first wife, Henry and Conrad, whom he caused each one during his lifetime to be elected king of the Romans; and by the daughter of King John of Jerusalem he had King Giordano, and by others he had King Frederick (from whom are descended the lineage of those who are called of Antioch), King Enzo and King Manfred, who were great enemies to Holy Church; and during his life he and his sons lived and ruled with much earthly splendour; but in the end he and his sons because of their sins came to an ill end, and their line was extinguished, as we shall make mention hereafter.

Inf. xxv. 1-3.] In the year of Christ 1228, when M. Andrea of Perugia was Podesta of Florence, the Florentines led an army against Pistoia with the Carroccio, and this was because the Pistoians were making war against Montemurlo, and ill-treating it; and the said host laid waste the country round about the city up to the suburbs, and destroyed the towers of Montefiore which were very strong; and the fortress of Carmignano surrendered to the commonwealth of Florence. And note that upon the rock of Carmignano there was a tower seventy cubits high, and thereupon two arms in marble, whereof the hands were 'making the figs' at Florence; wherefore the artificers of Florence, to express contempt for money or ought else offered to them, were wont to say: "I can't see it, for the fortress of Carmignano is in the way." And the Pistoians hereupon agreed to whatever terms the Florentines might devise, and caused the said fortress of Carmignano to be destroyed.
