Of course that wasn't enough, so the capstone was then plated in gold or electrum. Had the technology existed, we're sure the pharaohs would have stuck 24-inch chrome rims on them, too.
Why We Picture it Wrong:
What we're looking at today are the equivalent of sports cars that have been long forgotten in some junkyard.
Weather and time have been beating down the pyramids for four and a half thousand years. Well, partly it was time, but mostly it was assholes. Those shiny layers of white and gold? They were stripped off and used in the construction of Medieval Cairo, and there are cracks and holes where 19th century treasure hunters tried to get in with pickaxes and in one unfortunate case, dynamite.
Oh don't worry about it looters, those were only the greatest architectural accomplishments of the Ancient World. We're sure what you needed the stuff for was way more important.
