Chapter 10 focuses on the time scale of art history, which spans centuries or even millennia. It begins by showing how art historical processes can be interpreted in terms of complex dynamic systems. It then discusses patterns of art historical change, from linear to stepwise to metastable change. The chapter addresses the question of continuity and discontinuity in art history from both quantitative and qualitative perspectives. Finally, it discusses how the concepts and methods of network theory can help us to understand the complex dynamics of artworlds.

New circus/nouveau cirque is an artistic movement that circus historian Martine Maléval locates between 1968 and the 1990s. It can be described as both an aesthetic and a political revolution that was rooted in the dynamics of the social and cultural revolutions of the 1970s. For numerous reasons this period can be identified as the source of a renewed institutionalisation of the circus that is still ongoing. Commencing with the professional careers of circus artists who were active in the 1970s and the 1980s, this chapter examines how these artists progressively defined themselves as ‘circus authors’, how they promoted innovation in the aesthetics and practices of the circus, and how they generated a long-term impact on local cultural policies and the social status of contemporary circus artists in Europe. The process through which new circus emerged and evolved can be understood using the concept of ‘artification’ (becoming an art form), a term used by the French sociologist Nathalie Heinich and subsequently applied to circus studies by Magali Sizorn. Using Maléval’s foundational research on the French nouveau cirque as its point of departure, this chapter adopts a European-wide perspective to examine the influence of new circus from the 1990s until today.
