These Compositions are made with Belgian Rouge Griotte marble. This material was also used for both sculptures I.XI.XIV (2020) and I.XI.XIV (2022).  
In these compositions three cut-out shapes are recognizable as the shapes used in both sculptures. They are 3 of 15 shapes used in Conrad’s basic wooden toy set.  
Nr. I refers to the cube.  
Nr. XI refers to the bridge. 
Nr. XIV refers to the prism.  
Eleven Compositions I.XI.XIV have been created.
