Note 6 — Chapter II · THE GREEKS INTEREST EUROPE IN THE NILE QUESTION

Ptolemy’s original maps have disappeared, and we only know them through the well-nigh innumerable copies that were made by Greek monks between 600 and 900 A.D., by Arabs in the Islamic Renaissance, by Latin monks and pilgrims, by Venetian and Catalan sailors, and Flemish or German geographers. Latterly many of these copyists imported into Ptolemy’s maps of the Nile much recent and modern information.
