Purgatory

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.”
