The two Donatello's characteristic formal contributions are encountered in the work for Baptistery of Siena. He demonstated it through organizing the relief by a rigorous application of the rules of perspective. Even though it was created at a shallow deptht, this technique makes each figure of a scene emerge clearly and very logically. This technique is determined as a flattened relief.
        
                    
             
        
        
        
I feel like its more appropriate to leave artworks in a museum because if you leave them in their native settings it can possibly be destroyed or stolen. if you leave them in a museum it can be shown by lots of people who loved artwork and will pay billions to get one.
