In the thought-provoking book "Art in a State of Siege," Joseph Koerner explores the profound relationship between artworks and the tumultuous political landscapes that influence them.Through a detailed analysis of pieces created during periods of unrest, including Hieronymus Bosch's evocative "The Garden of Earthly Delights" and Max Beckmann's striking "Self-Portrait in Tuxedo," Koerner reveals how art communicates complex emotions and urgent messages.
