Commentary Purg VII 112-114

Large-limbed (membruto) like Cassius ([Inf XXXIV 67]), Pedro III, king of Aragon (1276-85), sings along with large-nosed Charles I of Anjou and Provence, king of Naples and Sicily (1266-85).  Pedro had married Constance, daughter of Manfred (see [Purg III 115-116]), in 1262, a relationship that gave him a claim to the crown of Sicily, which he assumed after the Sicilian Vespers (1282) and held until his death, despite the efforts of Charles, whom he had deposed and who died before Pedro, and thus without regaining his crown, in 1285.  Once again we see enemies united in friendship.
