Book excerpt: The title of this book, The European Avant-Garde – A Hundred Years Later, implies the European avant-garde took place a century ago, that it is a thing of the past. However, it does not aim to consolidate this position, but to question it. It addresses temporality as the central dimension related to the notion of the avant-garde. The book brings forth original revisions of the theories of the avant-garde, the works of the avant-garde, the idea of the avant-garde as being the vanguard, the leading force of change. It addresses the returning of the avant-garde during the twentieth century and today.
