From Chapter 47 of the Decline & Fall

Ludolph. Hist. Aethiopic. et Comment. l. i. c. 8. Renaudot Hist. Patriarch. Alex. p. 480, etc. This opinion, introduced into Egypt and Europe by the artifice of the Copts, the pride of the Abyssinians, the fear and ignorance of the Turks and Arabs, has not even the semblance of truth. The rains of Aethiopia do not, in the increase of the Nile, consult the will of the monarch. If the river approaches at Napata within three days' journey of the Red Sea (see D'Anville's Maps,) a canal that should divert its course would demand, and most probably surpass, the power of the Caesars.
