Definition of "Nubia"

Except date trees, and a few grape vines which I saw at Derr, there are no fruit-trees in Nubia.The climate of Nubia, though intensely hot in summer, particularly in the narrow rocky parts of the country, is very healthy, owing perhaps to the extreme aridity of the atmosphere.

1819, John Lewis Burckhardt, Travels in Nubia, Association for Promoting the Discovery of the Interior Parts of Africa, page 144

Our knowledge of Nubia at the end of the 19th dynasty gradually becomes sparser. It appears that the Egyptians withdrew to the north, while the local population emigrated to the south.

1978, Friedrich W. Hinkel, Exodus from Nubia, Akademie Verlag, page 27

Nubia is part of this landscape, created, formed and sustained by the Nile in complex interplays of geology and river hydrology.
