Commentary Inf XXV 139-141

Francesco, not identified until the last verse of the canto, turns momentarily away from Buoso, having regained his power of speech, only to use it to express his desire to punish him, addressing Puccio (see v. 148). As for Buoso, his identity is much debated. Michele Barbi (Barb.1934.1), pp. 305-22, suggests that he is probably Buoso di Forese Donati (died ca. 1285).
