There is probably nothing more fascinating or scary than the Dance Macabre which, in a time where death was all around. Wikipedia define it as consisting of the dead or a personification of death summoning representatives from all walks of life to dance along to the grave, typically with a pope, emperor, king, child, and laborer. It was produced as memento mori, to remind people of the fragility of their lives and how vain were the glories of earthly life. Its origins are postulated from illustrated sermon texts; the earliest recorded visual scheme was a now-lost mural at Holy Innocents' Cemetery in Paris dating from 1424 to 1425.
In this Atlas Obscura podcast, Caitlin Doughty, from “Ask a Mortician,” gives us a dance lesson in the two-step we were all born to do.
