Arthur Conan Doyle,
The Tragedy of the Korosko — Chapter I
(1896)
“ Beyond it there stretches on the Libyan bank a savage and illimitable desert, extending to the whole breadth of Africa. On the other side an equally desolate wilderness is bounded only by the distant Red Sea. Between these two huge and barren expanses Nubia writhes like a green sandworm along the course of the river. Here and there it disappears altogether, and the Nile runs between black and sun-cracked hills, with the orange drift-sand lying like glaciers in their valleys. Everywhere one sees traces of vanished races and submerged civilisations. ”
