The Histories · 2.16

If then we judge aright of these matters, the opinion of the Ionians about Egypt is not sound: but if the judgment of the Ionians is right, I declare that neither the Hellenes nor the Ionians themselves know how to reckon since they say that the whole earth is made up of three divisions, Europe, Asia, and Libya: for they ought to count in addition to these the Delta of Egypt, since it belongs neither to Asia nor to Libya; for at least it cannot be the river Nile by this reckoning which divides Asia from Libya, but the Nile is cleft at the point of this Delta so as to flow round it, and the result is that this land would come between Asia and Libya.
