Timosthenes, the admiral under Philadelphus, must not be forgotten in this list of authors; for though his verses to Apollo were little worth notice, his voyages of discovery, and his work in ten books on harbours, placed him in the first rank among geographers. Colotes, a pupil and follower of Epicurus, dedicated to Philadelphus a work of which the very title proves the nature of his philosophy, and how soon the rules of his master had fitted themselves to the habits of the sensualist. Its title was "That it is impossible even to support life according to the philosophical rules of any but the Epicureans." It was a good deal read and talked about; and three hundred years afterwards Plutarch thought it not a waste of time to write against it at some length. At a time when books were few, and far too dear to be within reach of the many, and indeed when the number of those who could read must have been small, other means were of course taken to meet the thirst after knowledge; and the chief of these were the public readings in the theatre. This was not overlooked by Phila-delphus, who employed Hegesias to read Herodotus, and Hermophantus to read Homer, the earliest historian and the earliest poet, the two authors who had taken deepest root in the minds of the Greeks. These public readings, which were common throughout Greece and its colonies, had not a little effect on the authors. They then wrote for the ear rather than the eye, to be listened to rather than to be read, which was one among the causes of Greek elegance and simplicity of style. Among others who were brought to Alexandria by the fame of Philadelphus' bounty was Zoilus, the grammarian, whose ill-natured criticism on Homer's poems had earned for him the name of Homeromastix, or the scourge of Homer. He read his criticisms to Philadelphus, who was so much displeased with his carping and unfair manner of finding fault, that he even refused to relieve him when in distress. The king told him, that while hundreds had earned a livelihood by pointing out the beauties of the Iliad and Odyssey in their public readings, surely one person who was so much wiser might be able to live by pointing out the faults. Timon, a tragic poet, was also one of the visitors to this court; but, as he was more fond of eating and drinking than of philosophy, we need not wonder at our knowing nothing of his tragedies, or at his not being made a professor by Philadelphus. But he took his revenge on the better-fed philosophers of the court, in a poem in which he calls them literary fighting-cocks, who were being fattened by the king, and were always quarrelling in the coops of the museum.
