I found where is another treasure online : all the beautiful plates from the " Description of Egypt" , commissioned and sponsored by Napoleon , created by some of most talented illustrators of that times .

That the Egypt at the times of Napoleon (1798 ),much of what illustrated doesn't exist any more.

Obviously at the times of Napoleon were no camera, that why Napoleon enrolled a legion of artists to document everything IN PLACE,
,then Napoleon took spoiled Egypt of most he could ,but has the merit to have documented how was ,

i just played with 1 of the illustrations i found ("Description of Egypt " is not one but a series of illustrated books on various aspect of Egypt, from art and monument to flora ,fauna etc) http://www.wdl.org/en/item/520/

Napoleon was nice enough to record what was but then fired cannon at the sphinx e.t.c so that those in the future could not appreciate Egypts true beauty
for themselves
