Dancing Plague of 1518

In July 1518, a woman began suddenly dancing on the streets. Within a month, 400 others had joined her—and nobody could stop. Many died from exhaustion.

The details of Arthur's existence are based on folklore and legend; historians agree that Arthur most likely did not exist. Regardless, Arthur's mythic power only grew stronger with each passing century.
