Abstract
The term ‘practice’ is used in a loose way in art theory. Using the example of the German artist Fritz Rahmann the text elaborates crucial aspects of artistic practice, taken as ‘bundles’ of different actions: clusters of similar actions, sequencing the clusters, exploring the dialogue with materials, relating them to mental models, ascribing them to social groups. In artistic practice the artwork loses its autonomy and the artist’s role as author is relativized. The approach opens a perspective on an art world that lost its overarching framework in globalization.
