As the blind man behind his leader walks,
Lest he should err, or stumble unawares
On what might harm him, or perhaps destroy,
I journey'd through that bitter air and foul,
Still list'ning to my escort's warning voice,
"Look that from me thou part not." Straight I heard
Voices, and each one seem'd to pray for peace,
And for compassion, to the Lamb of God
That taketh sins away. Their prelude still
Was "Agnus Dei," and through all the choir,
One voice, one measure ran, that perfect seem'd
The concord of their song. "Are these I hear
Spirits, O master?" I exclaim'd; and he:
"Thou aim'st aright: these loose the bonds of wrath."

"Now who art thou, that through our smoke dost cleave?
And speak'st of us, as thou thyself e'en yet
Dividest time by calends?" So one voice
Bespake me; whence my master said: "Reply;
And ask, if upward hence the passage lead."

"O being! who dost make thee pure, to stand
Beautiful once more in thy Maker's sight!
Along with me: and thou shalt hear and wonder."
Thus I, whereto the spirit answering spake:

"Long as 't is lawful for me, shall my steps
Follow on thine; and since the cloudy smoke
Forbids the seeing, hearing in its stead
Shall keep us join'd." I then forthwith began
