Hans Jörg Glattfelder, born in Zurich in 1939, is regarded throughout Europe
as one of the most important thinkers on Concrete Art. This recognition is
mainly based on two thematic areas: the series of pyramid reliefs, where
he explored the possibility of technical-industrial production of artworks in
the second half of the 1960s, and later the series of non-Euclidean metaphors, in
which he expanded the formal repertoire of concrete art by referring to scientific
methods (‘methodological constructivism’). The reflection on the scope of metaphor
in pictorial thinking, also developed in numerous publications, signifies a further
distancing from the conventions of concrete art. Glattfelder formulated this attitude
somewhat pointedly in the statement that he wanted to “give concrete art
back the dignity of questionability”.
