The publication of Greg M. Thomas' monograph on art and ecology in the landscapes of Théodore Rousseau in 2000 introduced ecocriticism into art history. Since then, numerous art historians have dealt with art from an ecocritical perspective. A revisionist view has emerged, especially since the Industrial Revolution, and a new art historical vocabulary primarily oriented towards the discourse of so-called New Materialism. The lecture serves as a material-oriented introduction to ecocritical art history, clarifying art-historically relevant terms and analyzing current eco-art.
