Can I have 11 years? Cause I'd like to slip Fagles' translations of
The Iliad and
Odyssey in there. This is so much more powerful than the Fitzgerald or Pope translations I can't express it.
The
Landmark Thucydides and
The Landmark Herodotus. These works can be extremely difficult to read out of context. These editions provide the context with voluminous notes and copious maps.
Martin's translation of
Ovid's Metamorphoses. This translation renders Ovid into a dignified but modern english. Ovid himself is a wild ride, and we tend to get our mythology from secondhand sources like Bullfinch and Hamilton who are pulling stuff from Ovid and Homer, better to get it from the source with the sustained grandeur intact.
So I guess, the best books of the last 10 years are 2000-3000 years old.
