Mary Bateman’s Eggs

Origin
Mary Bateman was a minor thief and con artist who often convinced many of her victims she possessed supernatural powers. By her later career, she claimed to be capable of warding off evil spirits. In 1806, she created a hoax known as The Prophet Hen of Leeds, where a hen laid eggs that predicted a doomsday event. In reality, she only inscribed a message on each egg and then re-inserted it back into the chicken. That same year, she was found guilty of killing a client with poisoned food instead of creating a protective charm.

Effects
