Are there any depictions of stone circles in heiroglyphs? (sp?)
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.
