The contrast between visible and invisible wounds is a central motif in the novel, challenging the military and medical establishment’s definition of a war casualty. The narrative consistently juxtaposes the tangible horrors of amputations, frostbite, and shrapnel with the misunderstood affliction of “Nervenshock” (111), or psychological trauma. While physical injuries are recognized and treated, and physically disabled soldiers are excused from further combat duties, the psychological wounds that arise from trauma are dismissed as cowardice or insubordination, directly illuminating the theme of The Invisibility and Misunderstanding of Psychological Trauma. This motif structures Lucius’s journey from a doctor focused on the body’s mechanics to one who must learn to recognize the injuries of the mind. He begins his studies with a desire for “an unusual aptitude for the perception of things that lie beneath the skin” (12), an ambition initially aimed at physical diagnosis but which finds its true test in the realm of psychology. Through this recurring contrast, the novel argues that war’s deepest injuries often leave no physical mark. The character of József Horváth embodies this conflict. When he first arrives at Lemnowice, he appears physically unharmed, and Lucius struggles to understand the cause of his catatonic state. Horváth’s trauma can only be glimpsed through his art, particularly his drawings of the Grottenolm, or blind salamanders. These creatures, a memory from Lucius’s own childhood, symbolize a hidden, fragile existence and the struggle to see the inner world of thought and feeling. The motif culminates in Lucius’s own experience with nightmares, demonstrating that no one, not even the doctor, is immune to war’s invisible wounds, which require empathy, not just a scalpel, to heal.
