Not that I know of. Hieroglyphs began in Egypt quite a while back, but the oldest surviving examples aren't long texts. Operative word there is "surviving" -- Egypt's population has lived in the flood plain of the Nile time out of mind, and those floods turn mud brick back to mud. In recent years I read that some outlines of ancient Memphis (which really was right on the river) were discerned using, oh, I forget -- ground penetrating radar, or satellite photography -- but that there's a distinct lack of artifacts found in test excavations carried out to study the ancient city.
It wouldn't be surprising if there was little left in Egypt since the empire fell apart over a period of time and people would have had time to grab anything useful. Babylon fell abruptly and the place would have been more or less deserted for long enough that the small pieces the army didn't want would be buried by the dust. Rome fell slowly and had time to move to Byzantium, but then Constantinople fell abruptly and everything was destroyed or looted. Kind of makes one wonder what will happen to America.
