 The subjects of maleness, violence and war tend to appear in association with one another; war is often commented upon but not necessarily from a purely pacifist perspective ("All Men Are Dangerous", "War Is A Male Preoccupation", "Keep The Faith", Tate Britain 2006; "I Don’t Understand Why There Is War", "The Question Mark Inside", St Paul's Cathedral, London, 2008; "War Is Always A Failure", "Complete Hero", Guards Chapel, London 2009).The majority of Firrell's works include some form of ancillary visual motif.Most common are vertical lines, either scrolling from left to right, or presented as static fields in "agitated motion".
