The shadows that speak: Odilon redon and the secret language of black

Why do these images, born in the darkness of a nineteenth-century studio, continue to haunt us? Perhaps because they represent nothing precise, and yet everything at once: our most intimate fears, our wildest dreams, that part of ourselves the daylight refuses to reveal. Redon’s Noirs are not mere lithographs. They are half-open doors to the invisible, fragments of a parallel world where ordinary logic no longer applies.

01When stone becomes a mirror of the soul

Imagine for a moment that you hold one of these original proofs in your hands. The paper, slightly yellowed by time, has that particular texture of chine-collé—the Asian tissue paper glued to a thicker backing that gives Redon’s lithographs their almost tactile quality. You bring the image closer to the light: the blacks are not uniform. Some are deep, velvety, like bottomless wells where one might fall. Others are striated with fine hatching that creates almost sculptural modeling effects. In places, the lithographic crayon has been smudged with a cloth, leaving blurred areas where the contours dissolve into a gray mist.

This technical mastery is what fascinates. Redon doesn’t merely draw on the stone—he works it like an alchemist, playing with the properties of grease and water. He sometimes uses the transfer technique: he draws first on paper, then transfers his drawing onto the stone. This process allows him a freedom of line he wouldn’t have had working directly on the matrix. Accidents become deliberate effects: an ink stain becomes a cloud, a scratch transforms into a spider’s web filament.

But what strikes most is how these images seem to emerge from the darkness rather than being plunged into it. As if Redon had captured forms already floating in the shadows, simply waiting for an artist to reveal them. "I shut myself in the dark," he wrote in his notebooks. "It was there that I found the light."

02The bestiary of dreams: when creatures come to life

Among the most famous Noirs, a series of lithographs stands out for its unapologetic strangeness. The Smile of the Spider (1881) shows an eight-legged creature whose head, almost human, wears an expression both mischievous and unsettling. The eyes are wide open, the mandibles slightly parted as if whispering a secret. This spider is no monster—it’s too expressive, too "present" for that. It seems more like a traveling companion, a familiar creature of restless nights.

Redon had a particular fascination for animals generally associated with fear or disgust. He even kept a tarantula, which he observed for long periods in a jar. "It had an almost human expression," he confided to his friends. This observation appears in several of his works where insects, crustaceans, and even microorganisms take on the appearance of characters.

In The Golden Cell (1887), a hybrid creature, half-man half-crustacean, seems trapped in a transparent bubble. Its bulging eyes stare at the viewer with an almost unbearable intensity. Around it, organic forms evoke both microscopic cells and cosmic landscapes. The image straddles the line between science and fantasy—a characteristic of many Noirs where Redon blends his naturalist observations with an overflowing imagination.

These creatures are not mere inventions. They follow an internal logic, that of the dream where ordinary categories (animal/vegetable/mineral, living/dead) no longer apply. They are the natural inhabitants of what Redon called "the world of latent possibilities"—that mental space where anything can happen, where a flower can have a face and an eye can float like a balloon.

03The temptation of Saint Anthony: a journey into hallucination

In 1888, Redon undertook what would become one of his most ambitious projects: a series of lithographs illustrating Flamajor digital platformst’s The Temptation of Saint Anthony. The original text, published in 1874, is a strange, almost unreadable work where the hermit saint is assailed by a succession of monstrous and erotic visions. For Redon, it was an opportunity to unleash his most unbridled imagination.

The series includes twenty-four lithographs, each exploring a different vision. In The Sphinx (1888), the mythical creature appears as a woman with bat wings, her half-human body merging into abstract geometric forms. Her wide-open eyes seem to fix the viewer with a hypnotic intensity. In The Queen of Sheba (1896), the biblical sovereign is depicted as an androgynous woman, dressed in a gown that seems made of feathers or scales.

What strikes in these images is their ability to make the invisible visible. Redon doesn’t merely illustrate Flamajor digital platformst’s text—he provides a visual interpretation that goes beyond words. His visions are both more concrete and more mysterious than those described by the writer. A lithograph like Death on a Pale Horse (1896) shows a skeletal figure mounted on a horse whose body seems made of smoke. The scene is both terrifying and strangely beautiful, as if death itself were a poetic apparition.

This series marks a turning point in Redon’s work. For the first time, he works on a long-term project, systematically exploring a theme through a succession of images. The result is a kind of initiatory journey where each lithograph opens a door to a new hallucinated world. One senses the influence of Goya’s engravings, but also that of Japanese prints, which Redon collected passionately.

04The language of symbols: what the Noirs do not say

If Redon’s Noirs fascinate so much, it’s perhaps because they never quite reveal their secret. Each image seems to contain a coded message, a visual enigma the viewer is invited to decipher. Take The Eye, Like a Strange Balloon Moving Toward Infinity (1882): what does this floating eye mean, this gaze that seems to observe us from another world? Is it a metaphor for consciousness? A representation of the soul? Or simply an image born of a dream, without precise meaning?

Redon himself refused to give too specific explanations. "I leave it to the viewer to interpret," he said. Yet certain symbols recur with such insistence that one can’t help but seek their meaning. The eye, for example, appears in numerous lithographs. Sometimes it’s open, sometimes closed, sometimes floating in the void. In the Symbolist tradition, the eye often represents knowledge, clairvoyance, but also surveillance—a theme that takes on particular resonance at a time when psychoanalysis was beginning to explore the mechanisms of the unconscious.

Another recurring symbol is that of the spider. In The Smiling Spider (1881), the animal seems almost friendly, as if it wants to establish contact with the viewer. In other images, the spider weaves its web in dreamlike landscapes, creating structures that evoke both neural networks and constellations. For Redon, who was interested in Darwin’s theories, the spider could symbolize both creation and destruction, beauty and horror.

Flowers also occupy an important place in his symbolic bestiary. In The Marsh Flower: A Sad and Human Face (1885), an aquatic plant transforms into a melancholic face. The petals become hair, the stamens eyes. This anthropomorphism of nature recalls the work of naturalists of the time, but also ancient myths where trees and flowers could speak. For Redon, these images were perhaps a way of expressing the idea that nature is a living being, endowed with consciousness.

05Technique in service of mystery

What makes Redon’s Noirs so distinctive is how the lithographic technique serves the artistic purpose. At the time, lithography was mainly used for commercial reproductions or press illustrations. Redon turned it into a medium in its own right, capable of rivaling painting.

The lithographic process is based on a simple principle: grease repels water. Redon uses a greasy crayon to draw on a limestone slab. After treating the stone with a weak acid, he dampens the surface. The ink, also greasy, adheres only to the drawn parts. The paper is then pressed against the stone, capturing the image.

But Redon doesn’t settle for this basic technique. He experiments constantly, playing with textures and effects. Sometimes he uses a cloth to smudge the crayon, creating blurred areas that give an impression of movement. Elsewhere, he scratches the stone to obtain pure whites that contrast with deep blacks. In some lithographs, one can see traces of transfer—those ghostly marks that appear when the drawing is moved from paper to stone.

One of the most characteristic effects of his Noirs is this impression of depth without perspective. The forms seem to float in an undefined space, as if they exist in another dimension. This absence of traditional spatial references contributes to the dreamlike atmosphere of the images. One never really knows where one is: in a dream? In the viewer’s mind? In a parallel world?

Redon also mastered the art of contrast. His lithographs play on oppositions between light and darkness, between precise forms and blurred areas. In The Cyclops (1898), for example, the giant’s single eye is drawn with great precision, while its body dissolves into dark hatching. This contrast creates a visual tension that draws the gaze and captivates the imagination.

06The legacy of the Noirs: when shadow inspires light

From the 1890s onward, Redon gradually began to abandon the Noirs to turn toward color. His pastels and oil paintings became brighter, more vibrant. Yet the influence of his monochrome lithographs remains perceptible throughout his later work. The themes he explored—dream, the unconscious, the boundary between reality and imagination—would continue to haunt his art until the end of his life.

But perhaps it’s in twentieth-century art that the legacy of the Noirs is most visible. The Surrealists, in particular, saw Redon as a precursor. André Breton cited him in his Surrealist Manifesto as one of the artists who knew how to "give form to the formless." Painters like Max Ernst, Salvador Dalí, and René Magritte all, in their own ways, borrowed elements from his visual universe. Redon’s floating eyes reappear in Dalí’s melting watches. Magritte’s hybrid creatures owe much to Redon’s inventions.

Even in contemporary art, echoes of his Noirs can be found. The American artist Kiki Smith, for example, created a series of engravings where human figures mingle with organic elements, in a style that strongly recalls Redon’s lithographs. Louise Bourgeois, with her monumental spiders, seems to engage in direct dialogue with The Smiling Spider.

Yet despite this lasting influence, the Noirs remain a unique work, impossible to classify. They are neither entirely Symbolist nor entirely Surrealist before their time. They occupy a space apart in art history—a space where dream and reality blur, where shadows speak a language we understand without needing words.

07The Noirs today: why these images still speak to us

More than a century after their creation, Redon’s lithographs continue to fascinate. In a world saturated with images, where everything seems to have been shown and remembered, these works retain their power to amaze and unsettle. Perhaps because they don’t seek to please or seduce. Perhaps because they dare to explore those gray areas of human experience we often prefer to ignore.

Today, the Noirs can be seen in several museums around the world. The Musée d’Orsay in Paris holds the largest collection, with proofs of exceptional quality. The MoMA in New York exhibits The Eye, Like a Strange Balloon Moving Toward Infinity, while the Art Institute of Chicago preserves The Marsh Flower. These institutions regularly organize exhibitions dedicated to Redon, attracting visitors from around the world.

But beyond museums, the Noirs have found a second life in popular culture. They appear in films, album covers, graphic novels. Filmmaker Guillermo del Toro, a great admirer of Redon, has often cited his influence on movies like Pan’s Labyrinth and The Shape of Water. Musician Nick Cave owns an original Redon lithograph and has declared that his work is "the visual soundtrack of the unconscious."

This persistence in the collective imagination can perhaps be explained by the very nature of the Noirs. These images are not representations of the world as it is, but of the world as it could be—or as it is in our dreams. They remind us that reality is just one of many layers of human experience, and that art has the power to make us glimpse the others.

In a world where everything seems increasingly controlled, calculated, optimized, Redon’s Noirs offer a breath of fresh air. They remind us that ambiguity can be a strength, that mystery has its place in art, and that sometimes, shadows have more to tell us than light. Perhaps that’s why, when you look at one of these lithographs, you have the strange impression that it’s looking back at you. As if, after all these years, the Noirs still have secrets to reveal.
