also famous : and the two Ptolemaei of Alexandria. the one black and the other white; and Zeno ° of Sidon. the pupil of Apollodorus. a voluminous author ; and Demetrius, 6 who was called the Laconian ; and Diogenes of Tarsus, who compiled the select lectures ; and Orion, and others whom the genuine Epicureans call Sophists. There were three other men who bore the name of Epicurus : one the son of Leonteus and Themista ; another a Magnesian by birth ; and a third, a drillsergeant. UjE-picurus was a most prolific author and eclipsed all before him in the number of his writings : for they amount to about three hundred rolls, and contain not a single citation from other authors : it is Epicurus himself who speaks throughout. Chrysippus tried to outdo him in authorship according to Carneades, who therefore calls him the literary parasite of Epicurus. " For every subject treated by Epicurus, Chrysippus in his contentiousness must treat at equal length ; hence he has frequently repeated himself and set down the first thought that occurred to him, and in his haste has left things unrevised, and he has so many citations that they alone fill his books : nor is this unexampled in Zeno and Aristotle." Such, then, in number and character are the writings of Epicurus, the best of which are the following : Of Nature, thirty-seven books. Of Atoms and Void. Of Love.
