Sec. 26.--_How the Florentines destroyed the castle of Frondigliano._ [Sidenote: 1199 A.D.] [Sidenote: Cf. Par. xvi. 62, 63.] In the year of Christ 1199, Count Henry della Tosa and his colleagues, being consuls of the city of Florence, the Florentines laid siege to the fortress of Frondigliano, which had rebelled and was making war upon the commonwealth of Florence, and they took it and destroyed it to the very foundations, and it was never built again. And in the same year the Florentines marched against Simifonte, which was a very strong place and did not obey the city.

Par. xvi. 62, 63.] In the year of Christ 1202, when Aldobrandino, of the Barucci of Santa Maria Maggiore (a very ancient family), and his colleagues were consuls in Florence, the Florentines took the stronghold of Simifonti, and destroyed it, and took the hill into possession of the commonwealth, forasmuch as it had been long time at war with the Florentines. And the Florentines gained it by the treachery of a certain man of Sandonato in Poci, which surrendered a tower, and claimed for this cause that he and his descendants should be free in Florence from all taxes; and this was granted, albeit the said traitor was first slain, in the said tower, by the inhabitants, as it was being attacked. And in the said year the Florentines went with their army against the fortress of Combiata, which was very strong, at the head of the river Marina, towards Mugello, which pertained to Cattani of the country which would not obey the commonwealth and made war against it. And when the said strongholds were destroyed, they made a decree that they should never be rebuilt.
