More than five centuries later (1320) Dante became the guest of Guido Novello di Polenta, lord of Ravenna, and here he died on the 14th September of the following year.
Count Giordano entered Florence, appointed Count Guido Novello podestd, and began a series of persecutions the city broke out between the consoli and the greater against the Guelphs.
After some disturbances Guido Novello and the Ghibellines were expelled, but it was not the popolo who triumphed; the pope and Charles were the real masters of the situation, and the Florentines found they had exchanged a foreign and Ghibelline protector for one who was foreign and Guelph.
There was considerable hostility between the newly entered family and the Salinguerra, but after considerable struggles Azzo Novello was nominated perpetual podesta in 12 4 2; in 1259 he took Ezzelino of Verona prisoner in battle.
Francesco Novello, his son, resisted bravely, but was compelled to surrender owing to dissensions in Padua itself.
Novello himself, besieged in his capital, although repeatedly offered favourable terms, held out for some months hoping for help from Florence and also from certain Venetian nobles with whom he was intriguing.
