Note 825 — CANTO XXXII.

Tribaldello: A noble of Faenza, who, as one account says, to revenge himself for the loss of a pig, sent a cast of the key of the city gate to John of Apia, then prowling about Romagna in the interest of the French Pope, Martin IV. He was slain at the battle of Forlì in 1282 (Inf. xxvii. 43).
