[Virgil]: "I only ask you this: refrain from talking.
Let me address them – I have understood
what you desire of them. Since they were Greek,
perhaps they’d be disdainful of your speech." (Inf. XXVI, 72-75)
I still was bent, attentive, over him [Guido da Montefeltro],
when my guide nudged me lightly at the side
and said: "You speak; he is Italian." (Inf. XXVII, 31-33)
Who, even with untrammeled words and many
attempts at telling, ever could recount
in full the blood and wounds that I now saw?
Each tongue that tried would certainly fall short
because the shallowness of both our speech
and intellect cannot contain so much. (Inf. XXVIII, 1-6)
