NO POEM HAS ever drawn the attention of so many exegetes as has Dante's Divina Commedia. It is probably fair to say that any young student of poetry who was aware of what is required of a dantista would happily choose to remain an amateur in respect to the poem, would choose to own it privately, only as it speaks to one's own eyes and ears. Dante himself is so much richer and deeper than we who write about him are, and allow him to seem, that the defender of the uses of the commentary tradition may be expected to display a certain hesitation. That tradition is so vast that those who decide to devote themselves to the study of it tend, understandably enough, to lose sight of the poem upon which this huge and unwieldly corpus sits. Nonetheless, we should probably observe that the originary fault lies with Dante himself. For no other poet has more evidently hoped to have a commentator at his margins. (Boccaccio, rightly, was so worried that no one would ever contribute a commentary to his Teseida that he supplied his own; and it was probably the existence of his own marginalia which encouraged at least two later and now mainly forgotten studiosi to supply their own.)
