Olafur Eliasson? Landscapes is a publication on Olafur Eliasson?s work 'Pentagonal mirror tunnel', a recent acquisition to the Saastamoinen Foundation Art Collection, and the related 'Olafur Eliasson: Pentagonal landscapes' project organised at EMMA.0The book?s articles are written by art historian Riikka Stewen and architect Juhani Pallasmaa. Riikka Stewen discusses in her article the thematic framework of 'Pentagonal mirror tunnel' and shows how perception and optics, illusion and disillusion are key to Eliasson?s work. Architect Juhani Pallasmaa writes in his article on the dialogue between science and art and how the two are reflected in Eliasson?s concept of art.0Olafur Eliasson is a conceptual artist whose art encompasses the domains of architecture, design, science and philosophy, and more specifically phenomenology. Eliasson?s art creates multisensory experiences and his creative process is based on an experimental approach to art. Experimenting, collaborating and interest in research are corner stones of his work. Eliasson counts among those contemporary artists who engage their audiences directly with the work of art. He sees his role as that of a catalyst who creates new connections between art and science.00Exhibition: EMMA Espoo Museum of Modern Art, Espoo, Finland (08.02.-21.05.2017).
