The silence that screams: When art transforms horror into memory
On April 26, 1937, at 4:30 PM, the air raid sirens blared over Guernica. German planes from the Condor Legion, Franco’s allies, dropped their incendiary bombs on the small Basque town. In three hours, 1,654 civilians died—crushed beneath rubble or burned alive. Among the survivors, a ten-year-old boy, Luis Iriondo, still remembers today how the sky "turned black, as if night had fallen in broad daylight." In Paris, a fifty-six-year-old Spanish artist, until then better known for his lovers than for his political commitments, shut himself in his studio on rue des Grands-Augustins. For thirty-five days, he painted without pause, covering a canvas nearly eight meters long with a frenzy of torn bodies, screaming horses, and grieving mothers. That painting, Guernica, would become the most famous anti-war work of the 20th century—a silent scream that echoes across the decades.

••16 min readYet Guernica is only one link in a long chain. Since man first waged war, he has also tried to represent it. But in the 20th century, something shifted. Artists no longer celebrated the exploits of heroes; they dipped their brushes into open wounds, turned the mud of trenches into pigments, and made pain a universal language. Otto Dix, the German soldier who saw his comrades rot alive in the trenches of the Somme, painted Der Krieg as if burying his nightmares. Käthe Kollwitz, whose only son died at eighteen in Flanders, carved into wood the image of a mother clutching her lifeless child. Their art is not a mirror but a scalpel: it opens flesh to show what official speeches seek to hide.
How does one represent the unrepresentable? How to give form to what, by definition, defies all form? These questions have haunted artists for a century. Their answers—often violent, always poetic—have redefined our relationship with history, memory, and even beauty. For in these works where death lurks with every brushstroke, something profoundly alive persists: a revolt, a tenderness, a stubborn belief that art can still save what war destroys.
01The trenches of memory: when realism becomes a weapon
Imagine stepping into an exhibition hall in 1924. The walls are covered with paintings in colors of rotting flesh and poisoned skies. At the center, a triptych draws all eyes: Der Krieg by Otto Dix. Visitors approach, fascinated and horrified. Some look away. Others, veterans, recognize in these faces twisted by suffering the features of their lost comrades. Dix did not paint war. He painted what it leaves behind: bodies that are no longer quite bodies, faces that are no longer quite faces.
What strikes first in Der Krieg is its almost unbearable realism. Dix, who served as a machine gunner on the Western Front, knew every detail of the horror. He saw men agonize for days, their wounds crawling with maggots. He smelled the acrid stench of mustard gas. He heard the cries of the wounded abandoned in no man’s land. All of this, he rendered with surgical precision. In the central panel, a soldier lies with his throat slit, his eyes glassy. His skin has taken on a greenish hue, as if death had already begun its work of decomposition. Beside him, another soldier, his face half torn away, seems to scream in silence. Further on, corpses pile up, some reduced to skeletons.
But Dix does not merely document. He transforms horror into allegory. The triptych, a format traditionally reserved for religious scenes, becomes here an anti-Pietà. The predella—the lower section that, in medieval altarpieces, often depicted scenes from Christ’s Passion—shows soldiers asleep—or perhaps already dead. Their slumber evokes that of the apostles in the Garden of Gethsemane, but also the numbness that precedes death. Dix plays with the codes of sacred art only to subvert them: there is no redemption in this war, only endless suffering.
What makes Der Krieg so powerful is this tension between the rawest realism and the darkest symbolism. Dix does not seek to shock for shock’s sake. He wants the viewer to feel the horror of war physically. The colors—those bilious greens, those pus-yellows, those ash-grays—are not chosen at random. They evoke the diseases that ravaged the trenches: gangrene, dysentery, infections. Even the texture of the paint, applied in thick layers on wood, recalls the mud of battlefields.
And then there is the question that haunts the work: who is looking at whom? In the left panel, soldiers march toward the front, their faces already marked by fatigue. In the right, survivors emerge from the trenches, haggard. But in the center, the decomposing corpse seems to stare at the viewer. As if Dix were saying: "You who look at this painting, you are complicit. You let this happen." A silent accusation, all the more terrible for its muteness.
02The canvas that resisted bombs: Guernica and art as an act of resistance
Back to that spring of 1937, in Picasso’s Paris studio. The walls are covered with preparatory sketches, bloodstained Spanish newspapers, photographs of the bombed city. The artist, who has not set foot in Spain for years, works with a feverish urgency. He knows this painting will be his weapon. Not a weapon to kill, but to awaken consciences.
Guernica is a strange, almost hallucinatory work. Nothing about it resembles what one expects from a war painting. No heroic soldiers, no flags waving in the wind. Only broken bodies, howling animals, a woman running with a kerosene lamp as if she could still light up the darkness. Picasso chose a monochrome palette, as if to mimic black-and-white press photos. But this absence of color only makes the work more violent. Gray becomes the color of ash, smoke, the dust of rubble.
What strikes is the lack of explicit references. No planes, no bombs, not even the name Guernica. Picasso erased all context. And it is precisely this that makes the painting universal. The bull, that ambiguous symbol—representing either fascist brutality or Spain itself—dominates the scene. The horse, pierced by a lance, seems to embody the Spanish people. As for the mother clutching her dead child, she evokes both the Christian Pietà and the grief of all mothers who have lost children to war.
But Guernica is also a deeply political work. Picasso, who had until then avoided partisan commitments, threw himself body and soul into the Republican cause. The painting was commissioned for the 1937 International Exposition in Paris, where it was meant to symbolize Spanish resistance. Yet when visitors discovered the work, many were disappointed. Some found the style too abstract, too removed from the reality of the conflict. Others criticized its lack of a "clear message." Picasso refused to explain. "The bull is a bull, the horse is a horse," he declared. "If you give meaning to certain things in my paintings, that may be very true, but it was not my idea to give that meaning."
Yet Guernica quickly transcended its original context. During World War II, the painting traveled the world, becoming a symbol of the fight against fascism. In 1939, it was sent to the United States for a touring exhibition. Picasso had demanded that it not return to Spain until democracy was restored. It would take until 1981, six years after Franco’s death, for the painting to finally reach Madrid.
Today, Guernica is more than a work of art. It is a monument, a memorial, an icon. But it is also an enigma. Why has this painting, more than any other, marked history? Perhaps because it does not show war, but its consequences. Not battles, but ruins. Not heroes, but victims. And above all, because it refuses to offer easy answers. Guernica does not console. It accuses.
03The hands that speak: Käthe Kollwitz and the art of mourning
There is something almost unbearable in Käthe Kollwitz’s engravings. Not because of their violence—they are, on the contrary, devastatingly sober—but because of their tenderness. In The Parents, a 1932 bronze sculpture, a man and a woman kneel, pressed together. Their bodies form a single mass of grief. Their faces, turned toward the ground, are nearly invisible. But their hands speak for them: the man’s, clenched on his knees; the woman’s, desperately searching for something—or someone—who is no longer there.
Kollwitz never experienced war firsthand. But she lived it through the death of her son. Peter, her youngest, enlisted as a volunteer in 1914, at eighteen. He died in combat a few weeks later, in Flanders. Kollwitz spent the rest of her life trying to give form to her grief. Her engravings, drawings, and sculptures are so many attempts to tame the unacceptable.
What sets her work apart is her refusal of grandiosity. Kollwitz does not depict war as a spectacle. She shows its intimate, almost domestic effects. In The Widow, a 1922 engraving, a woman sits with her hands clasped, her gaze lost in the void. Her body is hunched, as if crushed by the weight of her sorrow. Around her, emptiness. No decor, no context. Just this woman and her pain.
Kollwitz uses techniques that seem almost artisanal: wood engraving, lithography. Modest, inexpensive methods that allow for wide distribution. She does not seek to impress with technical virtuosity. What matters is raw emotion. Her lines are thick, almost clumsy. Her blacks are deep, like bottomless pits. Her whites, flashes of light that fail to pierce the darkness.
And then there are those hands. Always those hands. In Mother Protecting Her Child, a 1903 engraving, a woman clutches her baby to her, as if she could shield it from death itself. In The Survivors, a series made after World War I, hands reach toward the sky, as if pleading for an answer that will never come. These hands are Kollwitz’s universal language. They speak of fear, anger, despair. But also, sometimes, a strange tenderness.
Kollwitz paid dearly for her commitment. In 1933, the Nazis expelled her from the Prussian Academy of Arts. Her works were removed from museums, labeled "degenerate art." She continued to work in the shadows until her death in 1945. Today, her art is recognized as one of the purest expressions of human suffering. But also as an act of resistance. For by showing the grief of mothers, widows, and orphans, Kollwitz did what few artists had dared before her: she gave a voice to those whom war reduces to silence.
04The color of rotting flesh: when technique serves horror
There is something deeply unsettling in the way Otto Dix uses color. Not the bloody reds one expects in a battle scene. No, Dix prefers sickly greens, like those of gangrene. Pus-yellows. Ash-grays. In Der Krieg, these hues are not chosen at random. They are the result of a meticulous, almost clinical study of decomposition.
Dix served as a machine gunner during World War I. He saw men die of sepsis, their wounds rotting where they stood. He smelled the acrid stench of decaying flesh. All of this, he transcribed into his painting with almost unbearable precision. For Der Krieg, he used a rare technique in the 20th century: tempera on wood. A medieval process that gives the work a particular texture, almost rough. As if the paint itself were made of trench mud.
But what strikes most is how Dix plays with contrasts. In the central panel, a corpse lies in the foreground, its greenish skin standing out against the grayish background. Its eyes, wide open, seem to stare at the viewer. Beside it, a wounded soldier tries to drag himself from the battlefield. His face is half torn away, revealing muscles and bones beneath the skin. Dix does not soften reality. On the contrary, he makes it rawer, more tangible.
Picasso made a radically different choice. For Guernica, he opted for a monochrome palette, as if to imitate black-and-white press photos. But this absence of color only makes the work more violent. Gray becomes the color of smoke, dust, rubble. The bodies, reduced to angular shapes, seem made of the same material as the ruins around them.
Kollwitz, finally, uses black and white as a metaphor for death. Her engravings, with their violent contrasts, evoke photographic negatives. As if life had been erased, leaving only its shadow.
These technical choices are not trivial. They reveal something profound about how these artists conceive their role. Dix, with his almost medical realism, wants the viewer to feel the horror of war physically. Picasso, with his abstraction, seeks to transcend historical context to touch the universal. Kollwitz, with her simple lines and deep blacks, wants her art to be accessible to all, like a shared cry.
And perhaps this is where the power of these works lies: in their ability to use technique not as an end in itself, but as a means to convey the unspeakable.
05Art that survives censorship: when regimes fear images
There is something deeply ironic in the fact that authoritarian regimes, which distrust words so much, also fear images. Hitler, who presented himself as a failed artist, knew better than anyone the subversive power of art. In 1937, he organized the "Degenerate Art" exhibition in Munich, where works by artists deemed "decadent"—Kandinsky, Klee, Dix, Kollwitz—were displayed. Paintings were hung crooked, accompanied by mocking slogans. The goal? To show the German public that these artists were madmen, traitors, enemies of the nation.
Yet what the Nazis feared above all was precisely what these works represented: a truth they wanted to hide. Dix’s Der Krieg, with its disfigured soldiers and rotting corpses, contradicted the official propaganda that presented war as a noble and heroic enterprise. Kollwitz’s engravings, which showed the suffering of civilians, undermined the image of a united and victorious Germany. As for Guernica, though it was never exhibited in Nazi Germany, it had become a symbol of resistance to fascism.
The artists paid dearly for their freedom. Dix was expelled from his professorship at the Dresden Academy. His works were removed from museums. During the war, he was forcibly conscripted into the Volkssturm, the German people’s militia, and sent to the Russian front. Kollwitz was banned from exhibiting. Her engravings were removed from galleries. In 1943, her Berlin studio was destroyed by an Allied bombing. She died in 1945, days before the war’s end, without knowing that her art would outlive those who had tried to erase it.
Picasso was luckier. Exiled in France, he continued to work, protected by his international fame. But Guernica nearly disappeared. In 1939, as German troops approached Paris, the painting was rolled up and shipped to the United States for safekeeping. For years, it traveled the world, becoming a symbol of the fight against fascism. In 1958, Picasso refused to let it return to Spain as long as Franco remained in power. It would take until 1981, six years after the dictator’s death, for Guernica to finally reach Madrid.
This story reminds us of a fundamental truth: art is a weapon. Not a weapon to kill, but to resist. To say what authoritarian regimes want to silence. To show what they want to hide. And above all, to outlive those who try to destroy it.
06What remains when all is destroyed: art as memory
A question haunts all those who study war art: what is the point of representing horror? What is the point of painting corpses, engraving faces deformed by suffering, sculpting broken bodies? Do these works not risk becoming mere illustrations, macabre curiosities for history buffs?
The answer may lie in one of Kollwitz’s small engravings, Mother and Dead Child, made in 1903. A woman clutches the lifeless body of her baby to her. Her face is half-hidden, as if she does not want the world to see her pain. Yet what strikes is the tenderness of her gesture. Her hands, which cradle the child, still seem to protect him, as if she could bring him back to life through the sheer force of her love.
This engraving, made long before World War I, encapsulates the power of art in the face of war. It does not show the battle. It does not glorify heroes. It shows what remains when all is destroyed: love, pain, memory.
Dix, Picasso, and Kollwitz knew something that historians sometimes forget: war is not just dates, strategies, victories, or defeats. It is lived in bodies, in gazes, in trembling hands. It leaves traces that do not fade. And it is precisely this that these artists sought to capture: not the historical event, but its echo in flesh and soul.
Today, their works continue to speak to us. Guernica has become a symbol of civilian victims in all conflicts. Der Krieg reminds us that war is never truly won: it only creates losers. Kollwitz’s engravings, finally, remind us that behind every dead soldier, there is a mother, a wife, a child who mourns.
Art cannot prevent wars. But it can prevent their victims from being forgotten. And perhaps that is its greatest victory.
