Dante

If I had rhymes both rough and stridulous,
As were appropriate to the dismal hole
Down upon which thrust all the other rocks,
I would press out the juice of my conception
More fully; but because I have them not,
Not without fear I bring myself to speak;
For 'tis no enterprise to take in jest,
To sketch the bottom of all the universe,
Not for a tongue that cries Mamma and Babbbo.
