On this week's episode of the ArtTactic Podcast, host Adam Green speaks with Valentina Castellani, adjunct professor at NYU Steinhardt and author of Trading Beauty: Art Market Histories from the Altar to the Gallery, Castellani challenges the long-held idea that art and money exist in separate worlds, tracing how commerce has shaped the production and circulation of art from the Middle Ages to the present day. The conversation explores influential figures such as the pioneering Impressionist dealer Paul Durand-Ruel and the legendary partnership of Leo Castelli and Ileana Sonnabend, while also examining Castellani’s own experience working at Gagosian and organizing major historical exhibitions typically associated with museums. Together they discuss how the roles of galleries, museums, artists, and dealers have evolved over time and what the changing dynamics of representation, social media, and artist autonomy may mean for the future of the art market.
