On April 2, 1877, at London’s Royal Aquarium, a fourteen-year-old girl with the stage name Zazel became the first female to perform the human-cannonball trick in public. She later worked for P. T. Barnum, who, in response to the “Dangerous Performances Bill” under consideration by British Parliament, wrote defensively to the New York Times in 1880 that he paid Zazel $250 a day—“I should never have invested this large sum in any feature, however attractive, had I not known it was placed beyond the chance of accident.”

The second of the 282 laws in the Code of Hammurabi, dating from the eighteenth century bc, states, “If a man charge a man with sorcery, and cannot prove it, he who is charged with sorcery shall go to the river; into the river he shall throw himself, and if the river overcome him, his accuser shall take to himself his house. If the river show that man to be innocent, and he come forth unharmed, he who charged him with sorcery shall be put to death.”
