Sounds like I'll have to read Palma now. Curse you. :)
But yeah, the race is on for Purgatorio-- though I found an 1892 copy at the local library sale (!!) so I'm set for the moment.

I don't think any translation can be truly accurate if it turns a piece that flows in its original language into a stilted, prose-like beast in the translated language. Of course, the hard part is deciding how much text accuracy you're going to sacrifice to that end.
