Self-Flagellation
During outbreaks of the bubonic plague, some people engaged in self-flagellation, truly believing this could prevent the disease. This practice involved whipping oneself with a scourge or wearing a cilice, which was a spiked metal belt. Because many had the belief that plagues were punishments from God, it was thought one could atone for their sins and prevent the spread of the disease. Additionally, some people believed that the flagellation would stimulate the immune system and prevent the onset of the disease. Today, we know that diseases are spread by viruses, bacteria, and fungi rather than vengeful dieties.
