As a young man, Giacomo Casanova spent his nights roaming through Venice, “thinking up the most scandalous practical jokes and putting them into execution,” he later wrote in his memoirs. “When we could get into bell towers, we thought it great sport to alarm the whole neighborhood by ringing the tocsin that announces a fire, or to cut all the bell ropes…The whole city was complaining of our nocturnal malefactions, and we laughed at the investigations that were made to discover the disturbers of the public peace.”
