11 Paintings with Hidden Details Worth a Closer Look
Jan van Eyck was here!
Painted in 1434, The Arnolfini Portrait is one of the most studied and debated artworks in Western art history. At first glance, it shows a wealthy couple—traditionally identified as Giovanni di Nicolao di Arnolfini and his wife—standing in a richly furnished room. But almost every object in the painting seems to carry symbolic weight. The dog at their feet may represent loyalty. The oranges on the windowsill could suggest wealth or fertility. Even the way they’re holding hands has prompted endless discussion.
But the most striking detail is behind them: a small convex mirror hanging on the back wall. At first it might seem decorative. But if you look closely, you’ll see something extraordinary. The mirror reflects the couple from behind—and also shows two other figures standing just outside the painted scene. One of them is likely Jan van Eyck himself. Right above the mirror, there’s a Latin inscription that reads, “Jan van Eyck was here.”

An Unusual Royal Portrait
Painted in 1656, Las Meninas is one of Diego Velázquez’s most well-known works. At the time, he was working as court painter to King Philip IV of Spain. His job was to paint official portraits of the royal family—but here, he chose a different kind of scene.
Instead of a formal image of the king or queen, the painting shows a moment inside a room of the royal palace. At the center is the young princess, Margarita Teresa. Around her are her maids of honor, a dwarf, a jester, a dog, and a few other attendants. Velázquez includes himself, standing beside a large canvas. And in the background, there’s a mirror reflecting the king and queen—most likely standing just outside the frame, where we would be.
Even the title, Las Meninas, refers to the maids—not the royals! That tells us something about the focus of the work. Velázquez was interested in the daily life of the court, not just its official image. He often painted people behind the scenes: assistants, entertainers, workers.
A Garden Too Strange to Be Real
Painted around the year 1500, The Garden of Earthly Delights is the most famous work by the Dutch painter Hieronymus Bosch, and one of the most discussed paintings of the early modern period. The artwork is a triptych—a painting made of three panels—and was likely intended for private viewing rather than for a church. When closed, it shows a dull, grey image of the world on the third day of creation. But when opened, the viewer is met with something completely unexpected.
The left panel shows a lush, peaceful Garden of Eden. The right panel depicts a strange and terrifying version of Hell. But it’s the central panel—the so-called “garden”—that stands out. It’s filled with nude figures, oversized birds and fruits, hybrid creatures, and bizarre scenes that seem playful, chaotic, and at times unsettling. Although at first the images might seem joyful, many scholars believe Bosch was offering a warning about temptation and the dangers of indulging in earthly pleasures.
Kids often love spotting the weirdest parts: a man with flowers growing out of his body, someone trapped inside a giant musical instrument, a bird-headed monster eating people, and even a man with music written on his buttock! You can read the full story behind that hidden score here.

Deadly Perspectives
Painted in 1533, The Ambassadors by Hans Holbein the Younger is a large double portrait of two powerful men—Jean de Dinteville, a French ambassador, and Georges de Selve, a bishop and diplomat. They’re shown surrounded by globes, books, measuring tools, and musical instruments, all symbols of knowledge, culture, and worldly power. Holbein was known for his precise, almost photographic style, and every object here is painted with careful attention to detail.
Although the painting seems formal and almost still at first glance, it contains a striking hidden detail. Across the bottom of the composition, an elongated, smudged shape stretches diagonally across the floor. Viewed head-on, it looks like a strange blur. But if you move to the right and look from a sharp angle, the shape suddenly becomes a perfectly clear skull.
The skull is an example of memento mori—a Latin phrase meaning “remember you must die.” This tradition was common in Renaissance art, especially in Northern Europe, where symbols of death were included as reminders of mortality, no matter one’s status or intellect.
It’s a UFO!
This painting, known as The Madonna with Saint Giovannino, was produced in Florence in the late 15th century and is usually attributed to Domenico Ghirlandaio or his workshop, possibly Sebastiano Mainardi. It shows the Virgin Mary with the infant Jesus and a young John the Baptist. It’s a fairly typical devotional painting from the time, with calm expressions, soft colors, and a carefully composed landscape behind the figures.
But in the sky, just above Mary’s right shoulder, there’s something strange. A small, dark object hovers in the air, painted with rays of light extending from it. Below it, a man stands near the shoreline, shielding his eyes as he looks up at the object. At his feet, a dog also looks up, as if sensing something unusual.
The detail has puzzled viewers for decades. Although the painting was created long before the idea of UFOs existed, this particular element has often been brought up in modern discussions about “unidentified flying objects in art.” Most likely, it was meant as a symbolic light or vision—common in religious paintings—but its form is unusual enough to stand out. Whatever its meaning, it’s one of those small background details that rewards a closer look.
The Who’s Who of the Renaissance
Painted between 1509 and 1511, The School of Athens is one of Raphael’s most ambitious frescoes. It was commissioned by Pope Julius II to decorate the Stanza della Segnatura in the Vatican—a room used for both study and signing important documents. The painting represents classical philosophy and brings together ancient thinkers who never lived in the same time or place, gathered in an idealized architectural space.
At the center are Plato and Aristotle, walking side by side and debating the nature of knowledge. Around them, dozens of other philosophers, scientists, and mathematicians are arranged in animated poses—each one meant to represent a real historical figure, though Raphael didn’t always label them directly.
What makes this fresco especially interesting is that Raphael used real people from his own time as models for many of these ancient figures. Plato is based on Leonardo da Vinci. Heraclitus, seated alone and sketching in front, is modeled after Michelangelo, who Raphael greatly admired. And just to the right of the central group, looking out toward the viewer, is Raphael himself—young, modest, and tucked into the scene among the scholars.

A Monkey in Paris
Painted between 1884 and 1886, A Sunday Afternoon on the Island of La Grande Jatte is the best-known work by French artist Georges Seurat. It shows Parisians enjoying their day off in a park on the banks of the Seine. The painting is large, calm, and orderly—but it was also technically radical. Instead of mixing colors directly on a palette, Seurat painted the entire scene using tiny dots of color placed side by side. This method, called pointillism, was based on color theory and optical science. From a distance, the dots blend in the viewer’s eye.
The park is filled with still, quiet figures, but some of them are doing unexpected things. On the right, a woman walks a monkey on a leash—an unusual pet often linked to wealth or bohemian circles, where eccentricity and exotic animals were part of the image. On the left, near the riverbank, another woman holds a fishing rod. That detail might seem harmless, but at the time, this part of Paris was known as a place where bourgeois men met prostitutes. The fishing rod was likely a visual reference to that, more symbolic than literal. These small, strange details suggest that behind the calm surface of the painting, there’s another story about performance, social codes, and life in modern Paris.
Framing the Floor
By the early 1950s, Jackson Pollock had completely changed the way many people thought about painting. He didn’t work with a brush and easel in the traditional sense—instead, he rolled out enormous canvases directly onto the floor of his studio and painted standing over them, dripping, flinging, and pouring enamel house paint in energetic, overlapping lines. He often worked fast, moving rhythmically around the canvas, and didn’t plan the composition in advance. His approach was intense, physical, and all-consuming.
Pollock was a heavy smoker and often painted while holding a cigarette in one hand and a brush or stick in the other. It wasn’t unusual for ash, cigarette butts, or small bits of debris from the studio floor to land on the canvas while he worked.
Conservators have since found these traces embedded in many of his paintings, along with hair, footprints, and even buttons from his clothes. Rather than being removed, these accidental marks were left in place—they had become part of the painting.

A Special Kid
Painted in 1586 for the Church of Santo Tomé in Toledo, The Burial of the Count of Orgaz is one of El Greco’s most celebrated works. It was commissioned to commemorate a local legend: the nobleman Don Gonzalo Ruiz de Toledo, known as the Count of Orgaz, was said to have been so generous and pious that Saint Stephen and Saint Augustine descended from heaven to bury him with their own hands. The painting combines both the miraculous burial and a contemporary portrait of the people of Toledo watching the event.
What makes the painting especially interesting is how El Greco structured it. The lower half shows the physical burial, with richly dressed figures standing solemnly around the saints. The upper half shifts to a more spiritual realm, where clouds part to reveal angels, saints, and Christ himself receiving the Count’s soul.
But within this religious setting, El Greco included some very real people. The young boy in the foreground is his son, Jorge Manuel, and his name is written clearly on the handkerchief in his pocket. Just above, among the crowd of noblemen, El Greco included a self-portrait—positioned with discretion, but present all the same.

Not Who You Think They Are
Painted in 1930, American Gothic is one of the most recognizable American paintings of the 20th century. At first glance, it seems to show a stern Midwestern farmer and his wife standing in front of a white wooden house with a pointed Gothic-style window. Many assumed it was a commentary on rural American life, especially during the Great Depression. But the story behind the painting is a bit different—and more personal.
Grant Wood painted the house after spotting it in the small town of Eldon, Iowa. He found the architecture both charming and oddly serious, and imagined the kind of people who might live there. The man in the painting is not a farmer at all, but Wood’s dentist, whom he asked to pose while holding a pitchfork. The woman isn’t his wife either—it’s the artist’s sister, dressed in a colonial-style apron. Wood never intended the painting to mock or glorify rural life. He said it was meant to be a portrait of “a kind of American Gothic people,” inspired by a real house but shaped by imagination.
The result is a painting that looks like a slice of life, yet is actually a carefully staged construction—one that still raises questions about how Americans see themselves and each other.
The View From the Castle
The Très Riches Heures du Duc de Berry, made in the early 15th century by the Limbourg Brothers, is one of the most famous illuminated manuscripts in art history. But beyond its beauty, it also offers a revealing look at how peasants were viewed by the upper class.
Commissioned for the private devotion of Jean, Duke of Berry, this Book of Hours wasn’t made for the public—it was made for the duke’s eyes only. As a result, it’s filled with content that’s far less polished than what we might expect in a church altarpiece. On the calendar pages, peasants are shown doing seasonal labor, but also engaging in behaviors that border on ridicule: squatting in fields, slouching in the cold, even warming their genitals by the fire, as seen in the February page.
These details aren’t about realism or sympathy—they reflect a clear class bias. The nobility is shown hunting and feasting in fine clothes, while peasants are presented as rough, unrefined, and often laughable. This wasn’t an accident; it was part of how the ruling class saw themselves in relation to the people who worked their land.
