Rubens, or the art of painting diplomacy in red and gold

Rubens did not merely revolutionize Baroque painting. He turned it into a universal language, capable of flattering kings, seducing popes, and sealing alliances. Behind every canvas lies a negotiation; every color tells an intrigue. How could one man embody both the genius of the studio and the finesse of a diplomat? The answer lies in layers of paint, in the sidelong glances and outstretched hands of his figures.

01The workshop where the world is invented

Step into the Rubenshuis in Antwerp. The Flemish sun filters through the winter garden’s stained glass, casting shifting patterns across the easels. Here, between 1610 and 1640, far more than art was created—a true dream factory, where twenty assistants under the master’s direction produced canvases at a relentless pace. Rubens did not paint alone. He orchestrated, like a conductor, a symphony of specialized talents: Frans Snyders for animals, Jan Brueghel the Elder for flowers and landscapes, Anthony van Dyck for portraits.

The process was a well-oiled machine. Rubens began with oil sketches, modelli, where he fixed the composition, the play of light, and the expressions. These small canvases, now preserved as treasures, reveal a freedom of line that contrasts with the precision of the finished works. Then the assistants took over: they prepared the grounds, painted the draperies, the skies, the architecture. Finally, Rubens returned for the finishing touches, the details that bring faces and hands to life. A method that allowed him to meet the most demanding commissions, like the cycle of Marie de’ Medici—twenty-four monumental canvases delivered in three years.

But the workshop was also a school. Young artists came to learn the art of color, dynamic composition, visual storytelling. Rubens taught them to see the world as a stage, where every element must contribute to emotion. “Painting is silent poetry,” he liked to say. And in his studio, words were superfluous: everything was said through gestures, glances, brushstrokes.

02The palette of power

Look at The Judgment of Paris, one of his most famous works. The three goddesses—Hera, Athena, and Aphrodite—stand before the Trojan shepherd, each offering a gift in exchange for the golden apple. Their bodies, of milky whiteness, seem carved from antique marble. Yet Rubens does not copy statues: he animates them. The flesh pulses, the draperies slide like liquid silk, and the gazes, both provocative and calculating, betray political intelligence.

For this canvas is not merely a stylistic exercise. Painted in 1636 for King Philip IV of Spain, it is a subtle allegory of power. Paris, by choosing Aphrodite, triggers the Trojan War—a metaphor for the dangers of blind passion. But Rubens, the shrewd diplomat, slips in a more personal message. The goddess of love, crowned with flowers, bears an uncanny resemblance to Hélène Fourment, his young wife. A way of reminding even kings that they, too, are subject to the whims of the heart.

Color, for Rubens, is a weapon. His deep reds, drawn from cinnabar or madder, evoke both passion and power. His blues, obtained at great cost from lapis lazuli, symbolize divinity. As for his golds, they are not mere gilding: they catch the light like mirrors, turning every canvas into an object of fascination. “Color must sing,” he said. And in his work, it sings loudly.

03The brush and the sword

In 1628, Rubens left Antwerp for Madrid. Officially, he came to paint Philip IV’s portrait. Unofficially, he was tasked with negotiating peace between Spain and England. For eight months, he alternated between sittings and discussions with the Count-Duke of Olivares, the king’s powerful minister. His canvases, displayed in the palace galleries, served as calling cards. The Adoration of the Magi, with its Eastern kings prostrate before the Christ Child, evoked the universal power of the Habsburgs. The Garden of Love, where entwined couples dance beneath a summer sky, suggested the prosperity peace might bring.

Rubens mastered the art of suggestion. In The Allegory of Peace and War, painted for Charles I of England, Minerva, goddess of wisdom, pushes back Mars, god of war. The message was clear: peace is a victory, and England stood to gain everything. The canvas, now in London’s National Gallery, is a masterpiece of visual diplomacy. It helped seal the Treaty of Madrid in 1630, proving a brush could be as effective as a sword.

Yet Rubens was no mere propagandist. His most political works reveal a rare complexity. In The Horrors of War, painted in 1638, Mars, blinded by rage, tramples the arts and sciences beneath his feet. A denunciation of the ravages of the Thirty Years’ War, which was tearing Europe apart. Rubens, who had lost his first wife, Isabella Brant, in 1626, knew what he was talking about. Here, art was no longer a tool of power, but a cry of revolt.

04The body as landscape

Look at The Three Graces, one of his final works. Three women, with generous curves and rosy skin, embrace in an idyllic garden. Their bodies are not idealized in the manner of Greek statues: they are fleshy, almost tangible. Rubens does not paint goddesses, but women of flesh and blood. Their curves catch the light, their hands brush skin with a tenderness bordering on the erotic.

This sensuality is not gratuitous. It is the fruit of meticulous observation of the human body, nourished by anatomical studies and his travels in Italy. Rubens dissected cadavers, copied Michelangelo’s frescoes, analyzed antique sculptures. But unlike his predecessors, he did not seek perfection. He sought life. His nudes are not smooth: they bear the marks of time, the scars of existence. In The Rape of the Daughters of Leucippus, the women’s bodies, seized by Castor and Pollux, twist in a mix of terror and desire. Their muscles strain, veins rise beneath the skin. Violence and beauty intertwine, as in life.

This approach to the body scandalized the Puritans. In England, some of his works were deemed “too carnal.” Yet Rubens did not paint to shock. He painted to move. His figures are not symbols: they are human beings, with their strengths and weaknesses. Even in his religious scenes, like The Descent from the Cross, Christ is not an ethereal martyr, but a man whose body weighs heavily in the arms of those who carry him.

05The light that tells a story

In The Elevation of the Cross, a monumental triptych painted for Antwerp Cathedral, light does not merely illuminate: it sculpts. It falls diagonally, like a divine spotlight, highlighting the executioners’ taut muscles, Christ’s pained face, the Virgin’s desperate hands. Rubens studied Caravaggio, but he did not settle for chiaroscuro. He invented a Baroque light, theatrical, guiding the eye like an invisible hand.

This mastery of light was the result of a revolutionary technique. Rubens layered glazes—translucent layers of paint that gave colors unmatched depth. In Venus and Adonis, the goddess’s skin seems to radiate from within, as if made of pure light. To achieve this effect, Rubens used rare pigments: lead white for highlights, vermilion for warm shadows, lapis lazuli for celestial blues. Every brushstroke was calculated, yet the result was deceptively spontaneous.

Light, for Rubens, was also a narrative tool. In The Garden of Love, it dances across the lovers’ faces, accentuating their knowing smiles. In The Fall of the Damned, it fades gradually, plunging lost souls into darkness. Rubens did not paint scenes: he painted emotions, and light was their vehicle.

06The legacy of a one-man orchestra

Rubens died in 1640 in Antwerp, leaving behind more than 1,400 canvases. But his influence extended far beyond his studio. He invented the profession of painter-diplomat, proving an artist could be both creator and strategist. His students, like Van Dyck, spread his style across Europe, making Flemish Baroque an absolute reference.

Today, his works continue to fascinate. Curators at the Prado, the National Gallery, and the Louvre vie to display them. Art historians dissect his techniques, his symbols, his networks. Collectors pay fortunes for his sketches. And visitors, before The Garden of Love or The Three Graces, remain spellbound by this unique alchemy of sensuality, power, and poetry.

Rubens did not merely paint pictures. He painted dreams, alliances, revolts. He showed that art could be both mirror and weapon. And today, when you look at one of his canvases, you do not see only paint. You see history being written—in red and gold.
