(Ζηνόδοτος).
1. Of EPHESUS, a celebrated grammarian, was the first superintendent of the great library at Alexandria, in which office he was succeeded by Callimachus. He lived during the reigns of the first and second Ptolemies, the son of Lagus and Philadelphus, but as he was probably not appointed librarian till the reign of Philadelphus, he may be said to have flourished about B. C. 280. Suidas places him under the first Ptolemy, and says that he educated the children of Ptolemy; but it is more probable that these were the children of Philadelphus than of the first Ptolemy. Zenodotus was a pupil of the grammarian Philetas, who was probably also the instructor of Philadelphus.
