The Divine Comedy Volume II: Purgatory

O'er better waves to speed her rapid course
The light bark of my genius lifts the sail,
Well pleas'd to leave so cruel sea behind;
And of that second region will I sing,
In which the human spirit from sinful blot
Is purg'd, and for ascent to Heaven prepares.

Here, O ye hallow'd Nine! for in your train
I follow, here the deadened strain revive;
Nor let Calliope refuse to sound
A somewhat higher song, of that loud tone,
Which when the wretched birds of chattering note
Had heard, they of forgiveness lost all hope.

Sweet hue of eastern sapphire, that was spread
O'er the serene aspect of the pure air,
High up as the first circle, to mine eyes
Unwonted joy renew'd, soon as I 'scap'd
Forth from the atmosphere of deadly gloom,
That had mine eyes and bosom fill'd with grief.
The radiant planet, that to love invites,
Made all the orient laugh, and veil'd beneath
The Pisces' light, that in his escort came.
