Athenodorus found the city in this state, and for some time attempted to control Boëthus and his accomplices by argument; but finding that they continued to commit all kinds of injustice, he exerted the power given to him by Cæsar, condemned them to banishment, and expelled them. They had previously caused to be written upon the walls, “Action for the young, counsel for the middle-aged, discharging wind for the old;” but Athenodorus, accepting it as a jest, gave orders to inscribe by the side of it, “Thunder for the old.” Some one, however, in contempt for his good manners, having a lax state of body, bespattered the gate and wall of his house as he passed by it at night. Athenodorus, in an assembly of the people, accusing persons of being factiously disposed, said, “We may perceive the sickly condition of the city, and its bad habit of body, from many circumstances, but particularly from its discharges.” Those men were Stoics, but Nestor, of our time, the tutor of Marcellus, son of Octavia, the sister of Cæsar, was of the Academic sect. He was also at the head of the government, having succeeded Athenodorus, and continued to be honoured both by the Roman governors and by the citizens. 15. Among the other philosophers, “Those whom I know, and could in order name,”[261] were Plutiades and Diogenes, who went about from city to city, instituting schools of philosophy as the opportunity occurred. Diogenes, as if inspired by Apollo, composed and rehearsed poems, chiefly of the tragic kind, upon any subject that was proposed. The grammarians of Tarsus, whose writings we have, were Artemidorus and Diodorus. But the best writer of tragedy, among those enumerated in “The Pleiad,” was Dionysides. Rome is best able to inform us what number of learned men this city has produced, for it is filled with persons from Tarsus and Alexandreia. Such then is Tarsus.
