MacLeod 2000, hlm. 71. "The story first appears 500 years after the Arab conquest of Alexandria. John the Grammarian appears to be John Philoponus, who must have been dead by the time of the conquest. It seems, as shown above, that both of the Alexandrian libraries were destroyed by the end of the fourth century, and there is no mention of any library surviving at Alexandria in the Christian literature of the centuries following that date. It is also suspicious that Omar is recorded to have made the same remark about books found by the Arab during their conquest of Iran."
