The main theme of the text is the wartime and postwar history of the area of the German Nazi extermination camp Treblinka II, seen from the perspective of the production of landscape – with a special focus on the identity aspect, i.e. the nationalization of nature and the naturalization of the nation. The argument refers to imaging conventions of nature and ethnographic photography, like the German Heimatphotographie and the Polish Fatherland Photography, that go along with landscape production. This paper also touches upon the issue of classification as the principle organizing the workings of the human mind as well as the uses made of classification in terms of cognition and identity – up to and including the deadly consequences thereof. Another crucial point of reference is the history of the herbarium as a form of organizing knowledge (Maria Sibylla Merian, Rosa Luxemburg, Szymon Syreński) and its connections with the visual arts (Krzysztof Jung, Alina Szapocznikow). The rich iconography illustrates the analyzed representation patterns, with particular focus on the axiosemiotics of Polish antisemitism, going back to its elitist forms in Jagiellonian Poland. The text summarizes fifteen years of the author’s work on Herbarium, a photographic project carried out on the site of the former German Nazi extermination camp Treblinka II.
