The Sarcophagus of Menkaure
Of the three pyramids at Giza, the smallest one is the pyramid of the Egyptian pharaoh Menkaure. Built around 4,500 years ago, the pyramid stood unscathed for centuries until the British explorer, Howard Vyse, used explosives and other destructive means to bust into the structure and plunder its riches. One of the items he is said to have found is the intricate and detailed sarcophagus of the pharaoh.
Intent of sending his find back to the British Museum in London, Vyse loaded the priceless sarcophagus onto a merchant ship, the Beatrice, in 1838. The Beatrice, unfortunately, never made it to England. It sank during the voyage, taking the irreplaceable sarcophagus of Menkaure to the bottom of the sea.
