Commentary Inf XII 116-120

This slightly less bloodied crew contains 'mere' murderers, only one of whom is indicated (by periphrasis): Guy de Montfort (1243-1298), of royal English blood, in order to avenge his father Simon's murder killed his cousin, Henry of Cornwall in a church at Viterbo in 1271, supposedly while Henry was praying during the elevation of the Host. Henry's heart, returned to England, 'still drips with blood' because his murder was not avenged.
