Nothing compared to the looting in Egypt in the 19th and early 20th centuries were the tool of choice was dynamite.
The looting of Egypt was minimal in modern times, excluding the local yokels, who didn't use dynamite. Ancient Egypt's first looters were the ancient Egyptians themselves (first the pharaohs with their absolutism and aggrandizement, then the hoi polloi during periods of chaos); the Great Pyramid was open to tourists during classical antiquity, then closed up by the Byzantines, then chipped into by the nimrods who worked for the muzzie caliphs. One all-Egyptian village had a centuries-long secret looting thing that was finally detected and busted up by modern Egyptologists. Egyptologists also caught the local creeps who'd discovered the cache of New Kingdom pharaonic mummies and had planned to loot it out to the bare walls.
By contrast, the Etruscan excavations by the French in Italy (some relative of Napoleon III, if memory serves) dug up wonderful vases and other formerly unknown ceramics and other artifacts. They were selling the artifacts into the open market (mostly in Europe). The excavators had what should have been considered a great day -- a site yielded over 20,000 intact ceramic pieces such as jugs and urns, all nicely decorated. For fear the market for the Etruscan art would collapse, he ordered all of it smashed.
