NOTE: The skull is the most potent memento mori (a Latin term that translates as 'remember that you are mortal') in Western art as well as the most widespread personification of death. In the 17th century memento mori served as both as a warning symbol and an object for meditation. The present skull and bones was likely a model for a marble which would have sat in a church terminating a life-size crucifixion group reminding people of their own mortality.
