Paintings, sculptures, movements, and the human stories behind the works that changed how the world sees itself.
A close examination of Leonardo da Vinci's Mona Lisa reveals that the subject has no visible eyebrows or eyelashes. The most widely accepted explanation is that they were painted but have been worn away by centuries of cleaning and restoration. High-resolution scans conducted by engineer Pascal Cotte in 2007 appear to show traces of a left eyebrow that has faded over time.
Vincent van Gogh produced more than 2,100 works — including around 860 oil paintings — during a career spanning roughly a decade. Despite his extraordinary output, he sold only one painting while alive: The Red Vineyard, purchased in 1890 for 400 francs by the Belgian artist Anna Boch. Today his paintings regularly sell at auction for hundreds of millions of dollars.
The popular image of Michelangelo lying on his back to paint the Sistine Chapel ceiling is a myth. He and his assistants worked standing on a custom scaffold built close to the ceiling, leaning their heads back and painting upward. Michelangelo later wrote that the grueling four-year project left him with lasting neck and eye damage.
Cave paintings discovered in Leang Tedongnge cave in Sulawesi, Indonesia, have been dated to at least 45,500 years ago, making them the oldest known figurative art on Earth. The paintings depict warty pigs native to the region. Their existence pushes the documented origin of human artistic expression back thousands of years beyond previously known examples in Europe.
In 1911, the Mona Lisa was stolen from the Louvre in Paris by an Italian handyman named Vincenzo Peruggia, who had hidden inside the museum overnight. It was missing for over two years before being recovered in 1913. During the investigation, Pablo Picasso himself was brought in for questioning as a suspect — and was later released. Peruggia claimed he was simply returning the painting to its Italian homeland.
During the Renaissance, the pigment ultramarine — derived from the semi-precious stone lapis lazuli, mined almost exclusively in Afghanistan — was as expensive as gold by weight. Because of its staggering cost, it was typically reserved for the most sacred subjects in religious paintings, which is why the Virgin Mary's robes are depicted in deep blue across centuries of European art. Synthetic ultramarine was not developed until 1826.
The Smithsonian Institution is the world's largest museum and research complex, housing more than 155 million artifacts, specimens, and objects across its 19 museums and galleries. Despite that scale, the institution has space to display only about 1 percent of its total holdings at any given time. The vast majority of the collection is stored in research facilities and archives.
Grant Wood's famous 1930 painting American Gothic — depicting two stern figures with a pitchfork in front of an Iowa farmhouse — is widely assumed to show a husband and wife. In fact, Wood used his own sister Nan and his 62-year-old dentist, Dr. B.H. McKeeby, as the models. Wood described the figures as a father and daughter, not a couple. The painting now hangs at the Art Institute of Chicago.
In Michelangelo's The Creation of Adam on the Sistine Chapel ceiling, the shape formed by God, his angels, and the billowing red cloak closely mirrors the anatomical outline of a human brain when compared side-by-side. Some art historians and neuroanatomists have argued this was intentional — a hidden message from Michelangelo, who studied human anatomy by secretly dissecting cadavers, suggesting that the divine gift to humanity was the mind itself.
The Metropolitan Museum of Art's Costume Institute is the only curatorial department at The Met required to raise its own operating funds. To meet this requirement, the annual Met Gala was established in 1948. What began as a midnight dinner fundraiser has grown into one of the most publicized events in fashion and celebrity culture, raising tens of millions of dollars annually for the museum's fashion archive and exhibitions.
