In 2018 Volker Schnüttgen participated in an artistic residence in the Arts Centre of Caldas da Rainha where he conceived and produced the exhibition Sete livros sobre a natureza de uma árvore (Seven books on the nature of a tree) which evidences the connections which these bring from nature and the ones which establish with a process of thinking about Mankind and their psychosomatic and emotional structure in a context where, not rarely, we feel the urge to escape forwards, to the cosmos of our delusion, going back to the childhood dream of being an astronaut and being able to float in the universe as we watch life on Earth with the distance of the wise.
