Bonifazio, or Fazio, degli Uberti was a member of a Ghibelline family expelled from Florence in 1267. He was born in Pisa and never lived in Florence, the city of his ancestors, from which he considered himself an exile. Fazio was a court intellectual and a poet; his most important work is an encyclopedic poem called Il dittamondo. In 1336, he was in the service of Mastino II della Scala of Verona; in 1346, he was at the court of Luchino Visconti; and in 1358, he was in Bologna at the court of Giovanni Visconti d’Oleggio. Fazio’s adopted city was Verona, a bastion of Ghibelline and imperial ideals, where he probably died.
