Although anonymous works—those truly so and those deemed spurious—generally receive noticeably less scholarly attention than those whose authorship is uncontested, the work entitled Περὶ Κόσμου is too odd and too interesting to slip into the cracks of obscurity. Wilamowitz even included selections in his Griechisches Lesebuch (1902), and before him Stobaeus did the same, selecting all of chapters 2-5 and passages from chapters 6 and 7. Moreover, as Andrew Smith shows in this volume, it was also cited by name by such philosophers as Proclus and Philoponus, of the fifth and sixth centuries respectively, even though many of its ideas about nature were in no way original. Even more strikingly, Apuleius translated it loosely into Latin. So arguments from the silence of other sources about it do not carry any weight at all in judging its authenticity; certainly not a very fragmentary source like Philodemus, pace Thom on p. 7, although he is right to cite Philodemus’ statement that Aristotle did not try to convert Alexander to philosophy. More recently, it was reedited and commented on by Giovanni Reale and Abraham Bos.
