Library of Alexandria
Apollonius of Rhodes
Alexandria, Egypt
After Zenodotus either died or retired, Ptolemy II Philadelphus appointed Apollonius of Rhodes (lived c. 295–c. 215 BC), a native of Alexandria and a student of Callimachus, as the second head librarian of the Library of Alexandria. Philadelphus also appointed Apollonius of Rhodes as the tutor to his son, the future Ptolemy III Euergetes.
