A brief intellectual history of the idea of the art public. The Art Public explores the history of efforts to imagine a collective, general audience for art in the world. Oskar Batschmann explores both written and pictorial evidence of the development of the "art public" as an idea and disentangles connections between art production, audiences, and actual reception. Two aspects shape the the transformation of the audience from passive recipient to active agent as well as satirical jabs at audiences by the likes of Cruikshank, Rowlandson, and Daumier. This sweeping account connects the ancient Greeks with Renaissance painters, modern writers, and contemporary movie stars in a deft survey of the ways we imagine art's immediate impact on audiences and its afterlives in museums, galleries, and the world.
