	Gods Graves Glyphs	It's always been interesting; in the 1980s (I think it was) someone tried making bunches of polished bronze mirrors to try to set a dummy ship on fire using focused sunlight, and it didn't work. Nice that someone is taking the ancients at their word, and I'd hate to see Archimedes Screwed (/rimshot!) out of the credit, but this doesn't seem like any big deal to me, whether true or not. Used a catapault to chuck an incendiary onto attackers, whoa. :') To all -- please ping me to other topics which are appropriate for the GGG list.

A recent Mythbusters tried the same thing - a human could stand unprotected in the focus. The shields were just too diffuse.

Always thought it would be pretty hard to coordinate a group to be able to focus on one spot. Especially at what is probably a moving target.

They are still using Archimedes Screws to draw water from the Nile in Egypt. At least they were in the early 1980’s.
