Note 288 — CANTO VI.

But when, etc.: In the Inferno many such prayers are addressed to Dante. The shades in Purgatory ask to have their friends on earth stirred to offer up petitions for their speedy purification and deliverance; but the only alleviation possible for the doomed spirits is to know that they are not yet forgotten up in the ‘sweet world.’ A double artistic purpose is served by representing them as feeling thus. It relieves the mind to think that in such misery there is any source of comfort at all. And by making them be still interested on their own account in the thoughts of men, the eager colloquies in which they engage with Dante on such unequal terms gain in verisimilitude.
