The subject of this and the following books in the Spekulationen series is my approach to Stone Age art and its presence in my daily life. This volume mostly features photographs taken in everyday life and on trips, as well as found illustrations from scientific publications in various disciplines.

During his studies in Hamburg, Piller began working on the Peter Piller Archive, in which thousands of images and photos that he meticulously collected from sources such as magazines, the internet, postcards, and aerial photographs are organized, categorized, and assembled in series. His most important tools have always been his gift for precise observation and a subtle sense of humor, which allow Piller to discover serial, curious, and unusual elements in images that appear extremely banal and trivial, and to relate them to others. These include the aerial photo archive von erde schöner, based on 20,000 aerial photos and categorized into 23 series, which Piller has been working on since 2002.

His drawings and his own photographs are also always serial. For example, as part of the series Peripheriewanderungen, which he began in 1994, the artist wandered around places and subsequently made drawings and photographs of his walks. The drawings in particular are strongly associative and reflect personal impressions and emotions triggered by the walks rather than being actual documentations or maps. For the series behind time (2017), Piller traveled to various places around the world to observe and photograph rare and special birds. However, instead of depicting them in their full glory, as ornithologists would, the artist always shows them at the exact moment they leave his field of view and ironically names the photographs after the name of the species of bird he photographed. Piller is currently engaging with prehistoric cave paintings that were created in southern Europe during the Ice Age, before humans became sedentary. On this topic as well, he has collected hundreds of photographs and scans from various European libraries, and has taken photographs and made drawings on dozens of trips to southern France and northern Spain.

Piller has exhibited widely such as recently with Richard Prince at the Weserburg Museum, Bremen in 2021. Further solo exhibitions include the Staatliche Graphische Sammlung München; Mies van der Rohe Haus, Berlin; Museum für Kunst und Gewerbe, Hamburg; Deichtorhallen, Hamburg; Kunstverein Braunschweig; Kunstmuseum Bonn; Kunstforum Baloise, Basel; Witte de With Center for Contemporary Art, Rotterdam, among others. He has participated in numerous group shows, most recently at the Weserburg Museum, Bremen and Kunsthalle Düsseldorf, but also at Centre de la Photographie Genève; Walker Art Center, Minneapolis; Fondazione Prada, Milan; Lenbachhaus, Munich; MoMa PS1, New York City; Hamburger Bahnhof, Berlin, to name just a few. Peter Piller’s work can be found in public collections such as Kunstmuseum Bonn, Museum Ludwig, Cologne; San Francisco Museum of Modern Art; Fotomuseum Winterthur; Sammlung Falckenberg, Hamburg; Sammlung Rheingold, Mönchengladbach; Staatliche Kunstsammlungen Dresden, among others. Piller is a professor of fine art at the Kunstakademie Düsseldorf. Prior to this, he was the professor of photography at the HGB Leipzig, from 2006 to 2018.
