"Solid craftsmanship is certainly the foundation for the uniqueness of Hubert Rieber's work. Equally fascinating is the rigour of his formal vocabulary. Rieber's works stand in a sculptural tradition that brings together the human figure and geometric abstract form. Thus the figure is not just a matter of content but also of form. Yet regardless of the degree of abstraction, the size and proportion of his works consistently bring to mind the human figure."
