This edition of Apuleius's fragmentary works includes 62 items which, based on the most up-to-date scholarship, can be attributed with reasonable certainty to the 'lost Apuleius'. Passages known from oriental languages are presented here in a Latin back-translation, specially prepared for this edition. This edition is further enriched by 161 purported 'new fragments' of Apuleius embedded in Niccolņ Perotti's Cornu Copiae, a hitherto scarcely accessible set of dubious items which merit greater scholarly attention. An extensive praefatio (in Latin) surveys all the works either lost or falsely attributed to Apuleius, while also detailing the principles and methods underlying this edition.
