Note 425 — CANTO XIII.
James Romanes Sibbald translation
Of what thou thinkest, etc.: Virgil never asks a question for his own satisfaction. He knows who the spirits are, what brought them there, and which of them will speak honestly out on the promise of having his fame refreshed in the world. It should be noted how, by a hint, he has made Peter aware of who he is (line 48); a delicate attention yielded to no other shade in the Inferno, except Ulysses (Inf. xxvi. 79), and, perhaps, Brunetto Latini (Inf. xv. 99).
