The day Picasso shattered the Renaissance’s window

What unfolds in this Montmartre studio is not merely an aesthetic revolution. It is a cultural earthquake, a radical questioning of what it means to see. Until then, painting had been an open window onto the world, a faithful imitation of reality. With Cubism, it becomes an autonomous construction, a visual language that no longer seeks to deceive the eye but to provoke it. And what if this rupture had been prepared by centuries of history? What if, behind the sharp angles and geometric facets, lay an answer to the upheavals of a world in full mutation?

01The Renaissance’s cumbersome legacy

To grasp Picasso’s audacity, one must first measure the weight of the tradition he defies. Imagine Florence in the fifteenth century. Filippo Brunelleschi, a brilliant architect, has just devised a revolutionary system: linear perspective. By tracing converging lines toward a single vanishing point, he creates the perfect illusion of three-dimensional space on a flat surface. This discovery, theorised by Leon Battista Alberti in his treatise De Pictura (1435), would become the absolute dogma of Western painting for five hundred years.

The masters of the Renaissance seized upon this technique with enthusiasm. Masaccio used it in The Trinity (1425) to give the impression that the painted chapel recedes into the wall. Raphael, in The School of Athens (1510), composed a scene where each figure occupies a precise place in a mathematically constructed space. Even the Dutch still lifes of the seventeenth century obeyed these rules, with their tilted tables and glasses perfectly aligned toward an invisible vanishing point. Perspective became a religion, a universal language that every artist had to master.

Yet as early as the nineteenth century, cracks began to appear in this perfect edifice. Turner, with his misty landscapes, dissolved contours in light. The Impressionists, painting in rapid strokes, sacrificed precision of drawing for the sake of immediacy. But it was Cézanne who dealt the most decisive blow. In his still lifes, apples seem to roll off the table, planes overlap illogically. "Treat nature by the cylinder, the sphere, the cone," he wrote to Émile Bernard in 1904. Picasso read and reread these words. They contained the seed of the entire Cubist revolution.

02The shock of Les Demoiselles: when Africa meets the West

Let us return to that cursed canvas, Les Demoiselles d’Avignon. What strikes first is the total absence of depth. The five female figures seem crushed against the surface of the painting, as if Picasso had deliberately ignored the rules of perspective. The bodies are distorted, the faces reduced to angular masks. Two of the women, on the right, have features that irresistibly evoke the African sculptures Picasso had discovered a few months earlier at the Musée du Trocadéro.

This encounter with "primitive" art was a revelation. The Fang masks and Iberian statues, with their simplified forms and geometric volumes, offered Picasso a radical alternative to the Western tradition. They did not seek to imitate reality but to transcend it, to reach a deeper truth. In Les Demoiselles, the faces of the two figures on the right are no longer portraits but symbols. Their asymmetrical eyes, noses reduced to triangles, distorted mouths— everything contributes to creating an impression of violence and mystery.

But the innovation does not stop there. Picasso pushes the audacity further by representing the same face from multiple angles simultaneously. Observe the central figure: her nose is seen in profile, but her eye is frontal. This technique, which would become the hallmark of Cubism, definitively breaks the unity of the single viewpoint. The viewer is no longer a passive observer but an actor who must mentally reconstruct the space of the painting. It is a provocation, an invitation to rethink our way of perceiving the world.

03The Picasso-Braque rope team: an explosive collaboration

If Les Demoiselles d’Avignon marks the birth of Cubism, it is with Georges Braque that the movement truly takes flight. Their meeting in 1907 brought together two radically opposed temperaments. Picasso, impulsive and brilliant, painted like a demigod. Braque, methodical and reflective, constructed his canvases like an architect. Yet between 1909 and 1914, these two men formed an inseparable duo, an artistic "rope team" where each pushed the other toward ever more daring heights.

Their collaboration reached its peak with Analytical Cubism. Consider Braque’s The Portuguese (1911) or Picasso’s Portrait of Daniel-Henry Kahnweiler (1910): the subjects are decomposed into a multitude of geometric facets, as if the painting were seen through a kaleidoscope. Colours are reduced to a palette of greys, ochres, and browns, to avoid any emotional distraction. The goal? To push fragmentation to its limits, until the subject becomes almost unreadable.

This period was marked by constant emulation. The two artists worked side by side in their neighbouring studios, exchanging ideas, stealing techniques from each other. At times, they even signed their canvases with the same name to blur the lines. "We were like two mountaineers roped together," Braque would later say. This complicity gave rise to works where it was often impossible to distinguish one hand from the other.

Yet behind this apparent harmony lay a fertile rivalry. Picasso, always in search of new provocations, introduced collage elements as early as 1912. In Still Life with Chair Caning, he glued a piece of oilcloth imitating chair caning, creating the first Cubist collage. Braque, initially reluctant, eventually adopted the technique but added his own touch: he used newspaper clippings, sand, and even typographic letters to create compositions where reality and painting intertwined inextricably.

04The war that changed everything

The summer of 1914 marked a brutal turning point. The First World War broke out, and Braque was mobilised. Picasso, left behind in Paris, sank into deep depression. The "rope team" was broken, and with it, the golden age of Analytical Cubism. Yet this period of crisis would give rise to a new phase of the movement: Synthetic Cubism.

In the years that followed, Picasso and Braque, now separated, explored different paths. Picasso, freed from the constraints of collaboration, turned toward more colourful and legible compositions. In The Arlésienne (1912), he introduced floral motifs and vivid colours while retaining the geometric structure of Cubism. Braque, for his part, developed a more poetic style, where everyday objects— glasses, bottles, musical instruments— became the protagonists of still lifes of great delicacy.

But it was with Guernica (1937) that Picasso gave Cubism its most political dimension. This monumental canvas, painted in response to the bombing of the Basque town by Franco’s forces, employed the techniques of Analytical Cubism to create a powerful allegory of suffering and resistance. The distorted bodies, screaming faces, terrified animals— everything contributed to an impression of chaos and despair. Yet despite the fragmentation of forms, the work retained a dramatic unity that made it one of the masterpieces of the twentieth century.

05The forgotten figures of Cubism: when women reinvented art

While Picasso and Braque are the towering figures of Cubism, they were not the only ones to contribute to this revolutionary movement. Yet art history has often tended to obscure the role of women in this adventure. Marie Laurencin, for example, was the only woman to exhibit alongside the Cubists at the famous Section d’Or in 1912. Her canvases, with their pastel colours and refined forms, offered a more lyrical and feminine version of the movement. Yet her name is largely forgotten today, overshadowed by those of her male contemporaries.

Sonia Delaunay, meanwhile, pushed Cubism toward new frontiers with her "Orphism." In works like Bal Bullier (1913), she combined the geometric principles of Cubism with a palette of pure, vibrant colours, creating a unique style that foreshadowed abstract art. Yet like Laurencin, she was long relegated to the background, her work often reduced to a mere "variant" of Cubism.

These women artists, however, played a crucial role in the evolution of the movement. Their works, often more accessible than those of Picasso or Braque, helped popularise Cubism among a wider audience. They also demonstrated that Cubism was not a monolithic style but a plastic language open to multiple interpretations.

06Cubism in everyday life: when art invades objects

One of Cubism’s most radical innovations was its influence on the decorative arts. From the 1910s onward, the movement’s principles began to permeate design, architecture, and even fashion. The couturier Paul Poiret, for instance, drew inspiration from Cubism’s geometric forms to create dresses with angular lines and abstract patterns. In the 1920s, the Russian designer Erté took this logic even further, designing stage costumes that seemed to leap straight from a Léger canvas.

But it was in furniture design that Cubism’s influence was most visible. The French designer Eileen Gray, for example, created furniture in the 1920s with clean, geometric forms, such as her famous E-1027 table, whose straight lines and sharp angles recall Braque’s compositions. Similarly, Le Corbusier— though he denied being a "Cubist"— incorporated principles dear to the movement into his architectural projects, such as the superposition of planes and the fragmentation of volumes.

This permeability between art and design is one of Cubism’s most fascinating characteristics. By breaking down the boundaries between disciplines, the movement paved the way for a more holistic conception of creation, where painting, sculpture, and applied arts were no longer separate domains but facets of the same artistic approach.

07The legacy of Cubism: a language still alive

More than a century after its birth, Cubism continues to influence contemporary artists. Painters like David Hockney and Gerhard Richter have revisited its principles of fragmentation and superposition of planes to create works that engage with our era. In street art, artists like Banksy and Invader use techniques inspired by Cubism to create compositions where images decompose and recompose before our eyes.

But Cubism’s legacy is not limited to painting. In cinema, directors like Eisenstein and Godard have used editing techniques inspired by Cubist fragmentation. In music, composers like Stravinsky and Varèse explored rhythmic structures reminiscent of the superposition of planes dear to Picasso and Braque. Even in the field of virtual reality, Cubism’s principles— simultaneous representation of multiple viewpoints, deconstruction of space— find new resonance.

Yet beyond these technical influences, it is perhaps Cubism’s philosophy that remains most relevant today. By refusing to settle for a single vision of the world, by embracing complexity and the multiplicity of viewpoints, Cubism reminds us that reality is never as simple as it seems. In a world where images are everywhere, where information overlaps and contradicts, this lesson is more timely than ever.

08Epilogue: the broken window

Let us return one last time to the Bateau-Lavoir studio, on that evening in 1907 when it all began. Les Demoiselles d’Avignon still hangs on the wall, a silent witness to a revolution in progress. Picasso, a glass of absinthe in hand, watches his friends circle the canvas, perplexed. He knows he has done something irreversible. By shattering Renaissance perspective, he did not merely change painting. He changed our way of seeing the world.

Five centuries earlier, Brunelleschi had invented perspective to create the illusion of a window open onto reality. Picasso, for his part, broke that window. He forced us to look beyond, to accept that the world cannot be reduced to a single image, a single truth. In the geometric facets of his canvases, in the superposition of planes, in the collages that blend reality and painting, he captured something of the very essence of modernity: its complexity, its fragmentation, its instability.

Today, when you look at a Cubist work, you see more than just a painting. It is an invitation to rethink your relationship with the world, to accept that reality is always richer, more multiple, more surprising than what our eyes would have us believe. And if, in the end, that was the true revolution of Cubism?
