Commentary Inf XXXIV 20-21

Virgil uses the classical name for the king of hell, as he has once before ([Inf XI 65]), and as he did in his own poem (e.g., Aen. VI.269). This is the last time that we will hear that name, as we are shortly to leave his 'kingdom.' The phrase 'Ecco Dite' here surely echoes the phrase used of Jesus, before he is sentenced to death, 'Ecce homo.' See C.Inf.XVII.1-3.
