Sosicrates in the first book of his Successions, and Satyrus in the fourth book of his Lives, allege that Diogenes left nothing in writing, and Satyrus adds that the sorry tragedies are by his friend Philiscus, the Aeginetan. Sotion in his seventh book declares that only the following are genuine works of Diogenes: On Virtue, On Good, On Love, A Mendicant, Tolmaeus, Pordalus, Casandrus, Cephalion, Philiscus, Aristarchus, Sisyphus, Ganymedes, Anecdotes, Letters.

There have been five men who were named Diogenes. The first, of Apollonia, a natural philosopher.

The beginning of his treatise runs thus: At the outset of every discourse, methinks, one should see to it that the basis laid down is unquestionable. The second—of Sicyon—who wrote an Account of Peloponnesus. The third, our present subject. The fourth, a Stoic born at Seleucia, who is also called the Babylonian, because Seleucia is near Babylon. The fifth, of Tarsus, author of a work on poetical problems, which he attempts to solve.

Now the philosopher is said by Athenodorus in the eighth book of his Walks to have always had a sleek appearance owing to his use of unguents.[*](Cf. Epictet. iii. 22. 88 ὡς Διογένης ἐποίει· στίλβων γὰρ περιήρχετο καὶ αὐτὸ τὸ σῶμα ἐπέστρε φε τοὺς πολλούς.)
