Sec. 33.--_How the Florentines defeated the Sienese at Montalto._ Sec. 34.--_How the Sienese sued for peace to the Florentines and obtained it._ Sec. 35.--_How Otho IV. was crowned Emperor; and how he became the enemy and persecutor of Holy Church._ Sec. 36.--_How during Otho's lifetime Frederick II. of Suabia was elected Emperor by the desire of the Church of Rome._ The said Otho being the enemy of the Church, and being deposed by the general council of the Empire, the Church arranged with the electors of Germany that they should elect to be king of the Romans, Frederick, the young king of Sicily, who was in Germany, and he won a great victory against the said Otho; and afterwards the said Otho, returning to his duty, went on crusade to Damietta over seas, and there died, and the election was left to Frederick; and afterwards, in the time of Pope Honorius III., who succeeded to the aforesaid Innocent, the said Frederick of Germany came to Venice, and then by sea into his kingdom of Apulia, and then to Rome; and by the said Pope Honorius and by the Romans he was received with great honour, and crowned Emperor, as hereafter in treating of him we will make mention. We will leave speaking of the Emperor for a time, and will tell of the doings of the Florentines up to the time of his coronation.
