It should always do that because the `unerode' will use the same algorithms 
as the `erode'.

Wasn't the nose knocked off by French soldiers doing cannon practice? If it 
was, a drawing may yet be found. But what's happening about excavating around 
it? Anything yet? 
I am slightly inclined to the idea that the Egyptians never had the means to 
build the Sphinx or the pyramids, and that they are older than Pharaoic 
culture.
