To run o’er better waters hoists its sail
The little vessel of my genius now,
That leaves behind itself a sea so cruel;

And of that second kingdom will I sing
Wherein the human spirit doth purge itself,
And to ascend to heaven becometh worthy.

But let dead Poesy here rise again,
O holy Muses, since that I am yours,
And here Calliope somewhat ascend,
Divine Comedy, Purgatorio, Canto I.
