Amor, ch'a nullo amato amar perdona, mi prese del costui piacer sì forte, che, come vedi, ancor non m'abbandona. - Dante Alighieri

There are souls beneath that water. Fixed in slime
they speak their piece, end it, and start again:

'Sullen were we in the air made sweet by the Sun;
in the glory of his shining our hearts poured
a bitter smoke. Sullen were we begun;
sullen we lie forever in this ditch.'
This litany they gargle in their throats
as if they sand, but lacked the words and pitch.

¡Oh vosotros, que gozáis de sano entendimiento; descubrid la doctrina que se oculta bajo el velo de tan extraños versos!

And I was told about this torture, that it was the Hell of carnal sins when reasons give way to desire.
