At the crossroads of philosophy, artistic practice, and art history.Though Gilles Deleuze and Felix Guattari were not strictly art historians, they reinvigorated ontological and formal approaches to art, and simultaneously borrowed art historical concepts for their own philosophical work. They were dedicated modernists, inspired by the German school of expressionist art historians such as Riegl, Wölfflin, and Worringer and the great modernist art critics such as Rosenberg, Steinberg, Greenberg, and Fried. The work of Deleuze and Guattari on mannerism and Baroque art has led to new approaches to these artistic periods, and their radical transdisciplinarity has influenced contemporary art like no other philosophy before it. Their work therefore raises important methodological questions on the differences and relations among philosophy, artistic practice, and art history. In Art History after Deleuze and Guattari international scholars from all three fields explore what a 'Deleuzo-Guattarian art history' could be today.
