If you were starting to think that the 21st century has exclusive rights to violent imagery, this exhibition from the Art Institute of Chicago provides a correction. Dating back to the 1500s, the show includes both inspirational and terrifying visions of war, violence, and patriotism. One of the earliest works, by Master with the Mousetrap, c. 1512, The Two Armies at the Battle of Ravenna, depicts armies on the field of battle; Édouard Manet's Execution of Maximilian, 1867-68, shows Maximilian dying in front of the firing squad; and an American poster from the World War I era encourages citizens to "Buy a little present for the Kaiser" by purchasing a liberty loan. Visitors to the site can view the exhibition by themes, illustrated with eponymous artworks. For example, there is a theme entitled "The Cripples Portfolio", which includes a work by Heinrich Hoerle, The Married Couple, plate 2 (which is from Hoerle's The Cripples Portfolio (die Krüppel), 1920). This specific work shows a woman embracing a man who has come back from war with a hook in place of his left hand. Visitors who want to view all of the works can just click on the selected works section on the homepage to see all 31 items in the online show.
