Valentina Castellani, a former Gagosian director, has authored a new book titled *Trading Beauty: Art Market Histories from the Altar to the Gallery* (out 1 May). The book traces how art dealers have historically leveraged societal changes—political, economic, and social—to reshape taste and market structures. Castellani begins in the Middle Ages, when art was made only on commission for patrons like the Catholic church and monarchies, and moves through key shifts such as the Dutch Republic's first open art market in the 17th century, which gave rise to the professional art dealer. She highlights dealers like Paul Durand-Ruel, Joseph Duveen, and Leo Castelli who capitalized on anti-establishment energy, new wealth, and post-war consumer culture to bring avant-garde art to the forefront.
This analysis matters because it challenges the perception of the art market as an isolated monolith, revealing instead how deeply it is intertwined with broader historical currents. By examining the evolution of valuation criteria and the role of dealers as taste-makers, Castellani offers a framework for understanding how outsider artists and movements gain legitimacy and market value. The book underscores that the art trade is not static but continuously reshaped by external forces, providing context for contemporary market dynamics and the ongoing negotiation of artistic worth.
