My daughter says...
I got this for my daughter (16). She says it was good and translated in a way that was easier to enjoy than the books that other students in her class used.

An excellent translation of Aristophanes' finest works
This book, the fourth in Dr. Henderson's fine series of parallel translations, is perhaps the best of the series, containing as it does the comic masterpiece "Frogs," in my opinion the finest of Aristophanes' works. Henderson's translations are crisp, clear, and hilarious, and his extensive use of vulgarity is always textually and philologically sound (as a few comparisons of Liddell-Scott and the OED will surely reveal). In short, it is the definitive edition of Aristophanes' works, and the only translation accurate enough to be worth having on your bookshelf (and believe me, I've read quite a few).

THE modern Aristophanes translation
Professor Henderson's new translations of Aristophanes are uncensored, readable, fresh, and ultimately extremely enjoyable. He captures how Aristophanes probably would write if he lived today, with frank yet poetic language that brings these comedic gems to light. I have heard Professor Henderson's translation of Women at the Thesmophoria read aloud; the only thing funnier--and raunchier--I have heard since then has been a reading of his translation of Assemblywomen. Somehow Aristophanes manages to entertain his audience with the lowest of humor while invoking serious intellectual themes. (Imagine if people like Adam Sandler had brains. . .)
N.B. This is not your grandmother's Greek theater! Aristophanes, particularly as rendered by Professor Henderson, will make you rethink your notion of the Classics as dull, snooty, Stoic dust-gatherers in the far corner of the libary.
Enjoy!
