If, then, our judgment of this is right, the Ionians are in error concerning Egypt [30,27] (nation), Africa Egypt; but if their opinion is right, then it is plain that they and the rest of the Greeks cannot reckon truly, when they divide the whole earth into three parts, Europe (continent)Europe, Asia (continent)Asia, and Libya [17,25] (nation), AfricaLibya;

they must add to these a fourth part, the Delta of Egypt [30,27] (nation), Africa Egypt, if it belongs neither to Asia (continent)Asia nor to Libya [17,25] (nation), AfricaLibya; for by their showing the Nahr an- Nil [31.1,30.166] (river), AfricaNile is not the river that separates Asia (continent)Asia and Libya [17,25] (nation), AfricaLibya; the Nahr an- Nil [31.1,30.166] (river), AfricaNile divides at the apex of this Delta, so that this land must be between Asia (continent)Asia and Libya [17,25] (nation), AfricaLibya.
