Despite the widespread modern belief that the Library was burned once and cataclysmically destroyed, the Library actually declined gradually over the course of several centuries, starting with the purging of intellectuals from Alexandria in 145 BC during the reign of Ptolemy VIII Physcon, which resulted in Aristarchus of Samothrace, the head librarian, resigning from his position and exiling himself to Cyprus. Many other scholars, including Dionysius Thrax and Apollodorus of Athens, fled to other cities, where they continued teaching and conducting scholarship.

“The exact layout of the library is not known, but ancient sources describe the Library of Alexandria as comprising a collection of scrolls, Greek columns, a peripatos walk, a room for shared dining, a reading room, meeting rooms, gardens, and lecture halls, creating a model for the modern university campus.[29] A hall contained shelves for the collections of papyrus scrolls known as bibliothekai (βιβλιοθῆκαι). According to popular description, an inscription above the shelves read: “The place of the cure of the soul.”[30]”
