For more than thirty years, Thomas Huber (born 1955) has been exploring various manifestations and effects of an image in his predominantly architecturally influenced picture spaces. The volume primarily presents newly created works by the artist, who was born in Zurich and lives in Berlin, which relate to the horizon as a constant in all perspectively constructed images, as well as a metaphor for the boundary between the visibility of the motif and the invisibility of the artistic discourse associated with it. Texts by and a conversation with Thomas Huber illustrate the artist's systematic theory of images.
