Parsons, Alexandrian Library, p. 152; see also p. 229, where Parsons, citing a letter from Thomas E. Page to James Loeb, declares that “But for the patronage of the Ptolemies and the labor of devoted students in the Museum, Homer…might have wholly perished, and we might know nothing of Aeschylus…We still owe Alexandria a great debt.” Murray (Literature, p. 388) remarks, “Zenodotus, Callimachus [sic], Eratosthenes, Aristophanes of Byzantium, and Aristarchus were the first five librarians; what institution has ever had such a row of giants at its head?”
