not or
would not deal with him, nor be content that he should have the
Imperial rights, wherefore he subdued and smote Holy Church; or
because that God permitted it as a Divine judgment, because the rulers
of the Church had been the means through whom he became the child of
the holy nun, Constance, they not remembering the persecutions which
Henry, his father, and Frederick, his grandfather, had caused Holy
Church to endure. This Frederick did many noteworthy things in his
time, and raised in all the chief cities of Sicily and of Apulia,
strong and rich fortresses which are still standing, and built the
fortress of Capovana, in Naples, and the towers and gate upon the
bridge over the river of Volturno at Capua, the which are very
marvellous; and he made the park for sport on the marsh of Foggia in
Apulia, and made the hunting park near Gravina and Amalfi in the
mountains. 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.

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 w
