Those accussations against Vyse are quite serious, so let's check out the counter evidence; [doernenburg.alien.de], (several pages)
Frank Doernenburg; "So we do not have isolated names, the names were part of a whole sentence. The writer of these texts must have had not only knowledge about the Horus name, but also about how to use it and include it into a working group name. He needed knowledge no hieroglyphics expert of the 1840s had - knowledge of an ancient Egyptian!
The last possibility would be a working group name in a tomb discovered until 1837, but that is also no solution. Tombs containing that information were not found until the late 20th century! "
I'm not an expert in these matters, so I'll leave it to the jury...but I doubt that Vyse indeed had the knowhow to copy these names and sentences on the walls, the Horus name, the gangs...etc, although I must say that Sitchin presents it nicely, but is it all true?
