Numerous translations available. I prefer the Dorothy L. Sayers translation. Charles Williams recommended the book to her, and she first read it while sitting in a bomb shelter during a WW II London air raid. This was the major writing project that occupied most of the rest of her life, and the translation is well worth it.

Frequently referred to as "Dante's Inferno", this work is actually only the first part of his Divine Comedy, which tells an allegorical story about how God grants Dante a foretaste of hell, purgatory, and heaven, to free him from the error in which he was trapped. In this volume, Dante is led through the various circles of hell, seeing how the sins which people commit in this life work out in the next. In each case, the punishment suffered is simply the natural outworking of the sin committed.

Sayers' notes reveal the care with which she approached the translation, even duplicating Dante's metre and rhyme structure. If you don't really "get" poetry, don't let those notes scare you off. For the most part, the text reads quite clearly, and Sayers includes notes on the imagery and the characters, and a complete glossary of every person and place mentioned or alluded to in the text. – Greg Slade
