« This sculptural work is not only composed of light and materials but also of volumes … however none of these volumes is absolutely regular and perfect, there is always a slight asymmetry, a subtile instability, a discreet curve which brings the work to life.  We have also seen the interest of the open form, hollowed and cut out, which lets the light through and allows the eye to see what hides behind the work.  The principle of the full/empty fusion seems to be one of the decisive characteristics of Dietrich-Mohr. »
