A morphological survey of nested ivory spheres and polyhedra made by turning in Europe between the 16th and 18th centuries is presented, different polyhedra are identified, and examples of related objects of art of known ivory collections are shown. These examples convincingly demonstrate the high level of geometrical knowledge of the old master turners who produced these objects.
