When we were describing Arabia, we included in the description the gulfs which compress and make it a peninsula, namely the Gulfs of Arabia and of Persis. We described at the same time some parts of Egypt, and those of Ethiopia, inhabited by the Troglodytæ, and by the people situated next to them, extending to the confines of the Cinnamon country.791

We are now to describe the remaining parts contiguous to these nations, and situated about the Nile. We shall then give an account of Africa, which remains to complete this treatise on Geography.

And here we must previously adduce the opinions of Eratosthenes.
