The series Notizen zu Uecker (Notes on Uecker) makes the research findings of the Günther Uecker Institute’s scholarship holders accessible to the public. In volume 2, the author Xiao Xiao devotes attention to spiritual concepts from the East Asian region. Her analysis focuses on the astonishing affinity between philosophical notions of "action" in the Chinese-Daoist tradition and Uecker’s artistic practice. In volume 3, Nick Böhnke focuses on Uecker’s early "painterly actions" (1956-1958), which turn the painted work into an arena for tensions between the visual and tactile perception of pictorial space. An optical space is formed on the surfaces of Uecker’s structure and object paintings by varying incidence of light, an equally tactile space in the artist’s specifically performative approach.
