Note 704 — CANTO XXVII.
James Romanes Sibbald translation
But since, etc.: The shades, being enveloped in fire, are unable to see those with whom they speak; and so Guido does not detect in Dante the signs of a living man, but takes him to be like himself a denizen of Inferno. He would not have the truth regarding his fate to be known in the world, where he is supposed to have departed life in the odour of sanctity. Dante’s promise to refresh his fame he either regards as meaningless, or as one made without the power of fulfilling it. Dante leaves him in his error, for he is there to learn all he can, and not to bandy personal confessions with the shades.
