Demetrius of Phalerum, Librarian in the Library of Ptolemy I

According to Aristeas, Demetrius of Phalerum was in charge of the library under Ptolemy II. But there are others who argue that Zenodotus of Ephesus first held this post under Ptolemy II. On the other hand, if Demetrius was the first librarian in Alexandria, he was probably appointed by Ptolemy I and then continued to work for Ptolemy II. Aristeas could then be historically correct. It would also follow from such timing that the library was founded by Ptolemy I. This chapter examines the evidence in relation to the known historical facts concerning Demetrius and Zenodotus, and the textual evidence which is said to promote the claim of Zenodotus. It shows that the historical facts support the claim of Demetrius, and the textual evidence not only fails to support Zenodotus, but actually promotes Demetrius in this role.Keywords: Alexandria; Aristeas; Demetrius of Phalerum; Ptolemy I; Zenodotus of Ephesus
