But Sosicrates, in the first book of his Successions, and Satyrus, in the fourth book of his Lives, both assert that none of all these are the genuine composition of Diogenes. And Satyrus affirms that the tragedies are the work of Philiscus, the Æginetan, a friend of Diogenes. But Sotion, in his seventh book, says that these are the only genuine works of Diogenes: a dialogue on Virtue; another on the Good; another on Love; the Beggar; the Tolmæus; the Leopard; the Cassander; the Cephalion; and that the Aristarchus, the Sisyphus, the Ganymede, a volume of Apophthegms, and another of Letters, are all the work of Philiscus. XIII. There were five persons of the name of Diogenes. The first a native of Apollonia, a natural philosopher; and the beginning of his treatise on Natural Philosophy is as follows: “It appears to me to be well for every one who commences any kind of philosophical treatise, to lay down some undeniable principle to start with.” The second was a Sicyonian, who wrote an account of Peloponnesus. The third was the man of whom we have been speaking. The fourth was a Stoic, a native of Seleucia, but usually called a Babylonian, from the proximity of Seleucia to Babylon. The fifth was a native of Tarsus, who wrote on the subject of some questions concerning poetry which he endeavours to solve. XIV. Athenodorus, in the eighth book of his Conversations, says, that the philosopher always had a shining appearance, from his habit of anointing himself. LIFE OF MONIMUS. I. Monimus was a Syracusan, and a pupil of Diogenes, but also a slave of some Corinthian money-changer, as Sosicrates tells us. Xeniades, who bought Diogenes, used often to come to him, extolling the excellency of Diogenes both in actions and words, till he excited a great affection for the man in the mind of Monimus. For he immediately feigned madness, and threw about all the money and all the coins that were on the table, until his master discarded him, and then he straightway went to Diogenes and became his pupil. He also followed Crates the Cynic a good deal, and devoted himself to the same studies as he did; and the sight of this conduct of his made his master all the more think him mad. II. And he was a very eminent man, so that even Menander, the comic poet, speaks of him; accordingly, in one of his plays, namely in the Hippocomus, he mentions him thus:— There is a man, O Philo, named Monimus, A wise man, though but little known, and one Who bears a wallet at his back, and is not Content with one but three. He never spoke A single sentence, by great Jove I swear, Like this one, “Know thyself,” or any other Of the oft-quoted proverbs: all such sayings He scorned, as he did beg his way through dirt; Teaching that all opinion is but vanity. But he was a man of such gravity that he despised glory, and sought only for truth.
