Guido Novello da Polenta
Guido Novello da Polenta (c. 1275–1333) was lord of Ravenna from 1316 to 1322 and a poet. Son of Ostasio da Polenta, he succeeded his uncle Lamberto I, sought peace and encouraged a literary circle in Ravenna.
He is remembered as Dante's patron: the exiled Florentine lived in Ravenna from 1318, and when Dante died in 1321 Guido gave him a solemn funeral.
In 1322 he was elected captain of the people at Bologna and left Ravenna to his brother Archbishop Rinaldo, whom their cousin Ostasio I murdered while seizing the city. Guido died in 1333, having failed to reconquer Ravenna.
