boundary to the correspondence of the forms with their surrounding
        
        
          space.
        
        
          After a hiatus of about 20 years in which I did not work with reliefs, I took
        
        
          up this work again in a rather geometric form. It is less playful and thus
        
        
          represents the contrast of the strictness of my later years to the forms I
        
        
          invented in my middle years. Moreover, I have tried to produce a homo-
        
        
          geneity between the relief works and the embossed prints which allows
        
        
          the series to correspond harmoniously to each other. The light conditions
        
        
          of the surroundings are what give both series their effect. The owner of
        
        
          such a work is always challenged to find a place to hang it which corre-
        
        
          sponds to his notion of the best effect of the work. However, the works
        
        
          never remain the same in daylight. They are as alive as the fall of the light
        
        
          which awakens them to life.

          In 1998 I turned to sculpture for the first time. Here, the time tunnel
        
        
          dominates the intellectual orientation, and until now I have not taken
        
        
          any other paths with respect to sculpture, if one disregards the reliefs I
        
        
          made during the eighties. The possibilities of exploring this theme by
        
        
          designing different variants of the time tunnel, however, have not yet
        
        
          even come close to being exhausted. There is still considerable space
        
        
          here for creating something new.
        
        
          I feel a very close affinity to sculpture. For decades I have been studying
        
        
          the work of Eduardo Chillida. Together with my wife Yuko I visited him in
        
        
          San Sebastian and sought his friendship. As to my affinity to material, I
        
        
          am attracted equally to bronze and steel. The mere arduousness of the
        
        
          intellectual (and material) interaction with such masses of steel or
        
        
          concrete as Chillida was able to achieve keeps causing me to shy
        
        
          inwardly away from such heroic acts of coping with the material. Apart
        
        
          from Chillida, the work of Henry Moore has impressed me for several
        
        
          decades and, incidentally, also Hermann Noack and the wonderful
        
        
          craftsmen of his fine art foundry in Berlin, who cast most of these
        
        
          masterpieces of sculpture in bronze.
        
        
          Due to their three-dimensionality, it is often easier to endow sculptures
        
        
          and objects with the content of contemporary art in the context of poetic
        
        
          transformation and concretisation than it is to do so with paintings or
        
        
          graphic prints. This is especially true when thoughts, customs or myths
        
        
          have had an influence in creating the form. Thus, I showed my time
        
        
          tunnel to Frank-Thomas Gaulin and several friends at the Art Multiple
        
        
          exhibition in Düsseldorf in 1998. The time tunnel consists of a cube made
        
        
          of wood, metal or stone that has been hollowed out on the inside, giving
        
        
          it the form of a hollowed cube. The front side of the cube has equidi-
        
        
          stantly arranged, vertically positioned elongated slots. A piece of paper
        
        
          that has been rolled, carefully folded and tied with a hemp string is stuck
        
        
          into one (or more) of these slots. The time tunnel exhibited in Düsseldorf
        
        
          was made of beech wood and painted red on the four outer sides. Only
        
        
          the two surfaces that allow a look through the tunnel show the untreated
        
        
          material wood. With this choice of using colour, a certain tension occurs
        
        
          between the untreated material at the ends and the smooth coloured
        
        
          surfaces. Thus the impression is conveyed that the time tunnel is a
        
        
          segment, i.e. only a part, extracted from a much longer, perhaps infinitely
        
        
          long tunnel.
