This is like the medieval version of our superhero stories. And how it is ever so interesting to ponder the differences: the superpowers are created from a pact with the Devil (there are often allusions to the sinister powers or ways in which our modern superheros are created, but never the Devil himself), and the reward of these powers is a selfless penance and debasement to an anchorite life. The Empire and damsel are dangled before him as a reward, and he chooses a hermit-like oblivion and sainthood. This is something the modern superhero movies would never consider apart from the Luke figure in the last Star Wars.
A very enjoyable read. The translation breezes along, possesses some humor and keeps some rhymes (there's some couplets with just near-rhymes). I think the verse could be richer, but I have no idea if the original was richer. I'd like to give it 5 stars, but it does remind me of a modern superhero movie--entertaining, but without depth (albeit with much more depth than our modern tales).
