who wrote a local history in one volume ; the fourth a historian who wrote about the expedition of Pyrrhus into Italy and Sicily, and besides that an epitome of the political history of Rome and Carthage ; the fifth a pupil of Chrysippus, who left few writings but many disciples ; the sixth a physician of the school of Herophilus, a competent practitioner, though a poor writer ; the seventh a grammarian, who besides other writings has left behind him epigrams ; the eighth a Sidonian by birth and an Epicurean philosopher, lucid both in thinking and in style. Of the many disciples of Zeno the following are the most famous : Persaeus, son of Demetrius, of Citium, whom some call a pupil and others one of the household, one of those sent him by Antigonus to act as secretary ; he had been tutor to Antigonus's son Halcyoneus. And Antigonus once, wishing to make trial of him, caused some false news to be brought to him that his estate had been ravaged by the enemy, and as his countenance fell, " Do you see," said he, " that wealth is not a matter " of indifference ? The following works are by Persaeus : Of Kingship. The Spartan Constitution. Of Marriage. Of Impiety. Thyestes. Of Love. Exhortations. Interludes. Four books of Anecdotes. Memorabilia. A Reply to Plato's Laws in seven books.
