This is a general idea of the nature and effects of this river, so famous among the ancients. But a wonder so astonishing in itself, and which has been the object of the curiosity and admiration of the learned in all ages, seems to require a more particular description, in which I shall be as concise as possible.
1. _The Sources of the Nile._--The ancients placed the sources of the Nile in the mountains of the moon (as they are commonly called), in the 10th degree of south latitude. But our modern travellers have discovered that they lie in the 12th degree of north latitude; and by that means they cut off about four or five hundred leagues of the course which the ancients gave that river. It rises at the foot of a great mountain in the kingdom of Gojam in Abyssinia, from two springs, or eyes, to speak in the language of the country, the same word in Arabic signifying eye and fountain. These springs are thirty paces from one another, each as large as one of our wells or a coach-wheel. The Nile is increased with many rivulets which run into it; and after passing through Ethiopia in a very winding course, flows at last into Egypt.
2. _The Cataracts of the Nile._--This name is given to some parts of the Nile, where the water falls down from the steep rocks.(286) This river, which at first glided smoothly along the vast deserts of Ethiopia, before it enters Egypt, passes by the cataracts. Then growing on a sudden, contrary to its nature, raging and violent in those places where it is pent up and restrained; after having, at last, broken through all obstacles in its way, it precipitates itself from the top of some rocks to the bottom, with so loud a noise, that it is heard three leagues off.
The inhabitants of the country, accustomed by long practice to this sport, exhibit here a spectacle to travellers that is more terrifying than diverting. Two of them go into a little boat; the one to guide it, the other to throw out the water. After having long sustained the violence of the raging waves, by managing their little boat very dexterously, they suffer themselves to be carried away with the impetuous torrent as swift as an arrow. The affrighted spectator imagines they are going to be swallowed up in the precipice down which they fall; when the Nile, restored to its natural course, discovers them again, at a considerable distance, on its smooth and calm waters. This is Seneca's account, which is confirmed by our modern travellers.
