Mariele Neudecker uses a broad range of media, including sculpture, film, and sound. Her practice investigates the formation and historical dissemination of cultural constructs around natural and technological worlds, and notions of a Contemporary Sublime. Neudecker often reproduces a heightened landscape experience, addressing the subjective and mediated condition of any first-hand encounter.

, addresses the subject of landscape, its representation through art history and our subjective interpretation of it. Neudecker´s interest in landscape and nature has been influenced by the artistic, philosophical, historical, and political dimensions of the Romantic Sublime, as represented by the Northern European landscape painting of the 19th century. Paintings by Karl Friedrich Schinkel, Caspar David Friedrich, Johan Christian Dahl, among others, have been a strong influence on her work. - Over and Over and Again and Again, 2004
is tied closely to The- Gate in the Rocks
, a painting by Karl Friedrich Schinkel from 1818 and a symbol of Romanticism. The painting depicts a romantic landscape viewed through the opening of a cave. The painting's perspective is divided into three layers taking the eye from the cave to the rocks and all the way into the sky. Making the painting a point of departure for the work, Neudecker equally divides the landscape into three layers of perspective. By casting these into models, and organizing them consecutively into three sculpture tanks, Neudecker rebuilds the painting's initial perspective within the three-dimensional field. Thus, as the title of the work indicates, it becomes a mediated reproduction of a previous mediated experience of a given reality, achieved through the means of depiction and simulation. By addressing the principles and the threshold of temporary illusion, which determine the cognitive process, Neudecker tests the limits of illusion, thus blurring the boundaries between perception and representation, between the real and the artificial, between truth and imagination the past and the present.
