This weekend, I opened up my Rheinland-Pfalz bus-and-train circular and learned that the Reiss-Engelhorn Museums in Mannheim are hosting an exhibition that will run until late April dedicated to der Schädel. More than 300 items are on display: carved, painted, and revered by peoples from all over the world. What is the subject of this exciting and decidedly creepy exhibition? Der Schädel is a skull.
