Note 851 — Chapter I

George (Syncellus, or companion of the Patriarch), a writer of the eighth century, and who had the reputation of being well versed in history, says that “Ptolemy Philadelphus collected all the writings of Greeks, Chaldæans, Egyptians, and Romans, and had such of them as were not Greek translated into that language, and deposited 100,000 volumes at Alexandria. M. Letronne is disposed to think that Hipparchus, Eratosthenes, Ptolemy, and others borrowed from these sources.
