Loeb translations are often problematic. The books themselves are handy for having a bi-lingual text side by side but the English is often turgid, out of date and can be quite inaccurate.
However the new Aristophanes are, IMO anyway, a fantastic departure from the norm. Jeffrey Henderson has written a very funny, vivid and fast paced translation without seeming overly-modern and anachronistic.
Proof that Aristophanes can still be hilarious! ( )
