The nursery rhyme Ring around the Rosie came about during the time of the Black Death. Here are what the lyrics mean: Ring around the rosie is a reference to the black sores that would appear on your body as part of the plague. Your rosie is around the center of the back of your hand. A pocket full of posies is a reference to people would carrying posies (flowers) around to not smell the sickening scent of dead bodies everywhere. Ashes Ashes signifies the ashes from all the bodies being burned on pyres. Bodies couldn't be buried or else the infection would spread.
