Each bead of the rosary represents the bust of a well-fed burgher or maiden on one side, and a skeleton on the other. The terminals, even more graphically, show the head of a deceased man, with half the image eaten away from decay. Such images served as reminders that life is fleeting and that leading a virtuous life as a faithful Christian is key to salvation. More images and info at Met Museum of Art. If anyone out there is thinking about making any replicas, I would love one!
