Callimachus (c. 305–235 B.C.E.) served under four successive chief librarians as the collector and collator of the Alexandria Library. He produced a 120-volume catalogue, called the Pinakes, of the library’s 500,000 books (that number would reach 1,000,000 by the time of Jesus). The Pinakes contained information on each book’s contents, provenance and author. After the library was destroyed in the seventh century C.E., many of its surviving books were apparently carried off to the imperial libraries of the caliphates, where they were translated into Persian and Arabic.
