The Silver Tassie is a four-act Expressionist play about the First World War, written between 1927 and 1928 by the Irish playwright Seán O'Casey.[1] It was O'Casey's fourth play and attacks imperialist wars and the suffering that they cause. O'Casey described the play as "A generous handful of stones, aimed indiscriminately, with the aim of breaking a few windows. I don't think it makes a good play, but it's a remarkable one."[2]
