A vast majority of manuscripts and printed editions read in this line, Re Giovanni , King John, instead of Re Giovane , the Young King. Even Boccaccio’s copy, which he wrote out with his own hand for Petrarca, has Re Giovanni . Out of seventy-nine Codici examined by Barlow, he says, Study of the Divina Commedia , p. 153, “Only five were found with the correct reading⁠— re giovane .⁠ ⁠… The reading re giovane is not found in any of the early editions, nor is it noticed by any of the early commentators.” See also Ginguené, Histoire littéraire de l’Italie , II
