ROGER2. Ruggieri degli Ubaldini was archbishop of Pisa and a member of the Ghibelline party in the years 1278-1295. Count Ugolino della Gherardesca betrayed the Guelphs to him, and he betrayed Ugolino, who was imprisoned with his sons in the Tower of Famine, where they starved to death. Dante places Ruggieri and Ugolino in Antenora among traitors, in the second division of the Ninth Circle of Hell, where Ugolino gnaws on Ruggieri's head (Inf XXXIII.1-90).
The Monk tells the story, MkT 2407-2462. Chaucer omits the cannibalism of Dante's version. [Hugelyn]
