81: According to the Babylonian Talmud[8], an insect flew into the Roman emperor Titus's nose and picked at his brain for seven years. He noticed that the sound of a blacksmith hammering caused the ensuing pain to abate, so he paid for blacksmiths to hammer nearby him; however, the effect wore off and the insect resumed its gnawing. When he died, they opened his skull and found the insect had grown to the size of a bird.
