”On re-reading the second quotation, the context certainly suggests that Osburn was talking about the name as a quarry mark. What he does not make clear is who is supposed to have observed it or reported it. Surely Lepsius and crew would have spotted it, when they were there?”
Again, from Osburn page 275:
”About four years after this identification [the name of Suphis by Champollion], Col. Vyse discovered the same name traced in minium upon the blocks in the interior of the Great Pyramid”
The Prussian expedition was in late 1842.
Am I missing something?
