The pyramids are amazing. Because you know we could never make the pyramids today. The same of the Colossus of Rhodes. Like Shakespeare said in Julius Caesar, "Why, man, he doth bestride the narrow world like a Colossus." Some people think that the statue straddled the harbor. If it did that was an amazing piece of engineering. Because they would have to built up both legs from either side, while making sure the massive structure didn't collapse.
