All About Switzerland:
Under the roof of Spreuer Bridge, 67 paintings dating from 1626 to 1635 represent a Dance of Death. Death, represented as a skeleton or as the Great Reaper urges everybody to dance with him. Death makes no difference between old and young, churchmen and laymen, rich and poor. These kinds of paintings were often placed on cemetary walls. They expressed popular feeling in the face of death, especially during times of epidemic pestilence... Lucerne's Dance of Death was designed by chief painter Kaspar Meglinger.More here and here.
