Ben Edwin Perry's Aesopica remains the definitive edition of all fables reputed to be by Aesop. The volume begins traditionally with a life of Aesop, but in two different and previously unedited Greek versions, with collations that record variations in the major recensions. It includes 179 proverbs attributed to Aesop and 725 carefully organized fables, for which Perry also provides their eldest known sources. To better evaluate the place of Aesop in literary history, Perry includes testimonies about Aesop made by Greek and Latin authors, from Herodotus to Maximus Planudes.
