Here is a slick-covered paperback--it actually looks like a Penguin paperback--offering Phaedrus' five books and Perotti's Appendix with matching Italian prose translations. Of the several bilingual translations of Aesop and Phaedrus that I found on this trip to Italy, those from Mondadori are the sturdiest and best-made books. Among the Phaedrus editions, this also has by far the most extensive introduction, bibliography, and notes. The T of C at the back lists only books, not fables, and there is no AI. One can locate fables faster in other volumes, but then I think this edition will have more to offer once the fable is located.
