In short: Painted on walnut wood around 1490, this portrait of Cecilia Gallerani captures the mistress of the Duke of Milan in a dynamic, spiraling pose. Far from a simple likeness, the painting uses a symbolic animal to convey complex themes of purity, pregnancy, and political loyalty within the Sforza court.

The Lady with an Ermine is a seminal work by Leonardo da Vinci, executed on a thin walnut panel during his first Milanese period, roughly 1489–1491. The sitter, Cecilia Gallerani, was the young mistress of Ludovico Sforza, the Duke of Milan. Leonardo’s composition is revolutionary for its time, utilizing a pyramidal spiral that captures the subject in a moment of motion—a hallmark of his lifelong fascination with movement. The painting is also notable for its technical sophistication, featuring subtle remains of spolvero and underdrawing, alongside fingerprints that suggest the artist’s direct, tactile involvement.

The central animal, often identified as an ermine, is likely a symbolic composite rather than a literal representation. In Renaissance culture, the ermine was a potent emblem of purity and moderation, famously believed to prefer death over soiling its white coat. Beyond this, the animal serves as a clever visual pun on Gallerani’s surname, derived from the Greek 'galê' for weasel. Scholars also suggest the ermine alludes to her pregnancy with the Duke’s son and her impending marriage to Count Ludovico Bergamino, as the animal was frequently associated with chastity and marital fidelity in contemporary literature, such as Petrarch’s I Trionfi.

The portrait’s history is as dramatic as its composition. Long considered damaged and heavily repainted, a 1992 technical analysis confirmed that the primary degradation was limited to the background, which had been overpainted in black during the 18th century. After being acquired by Prince Adam Jerzy Czartoryski in 1798, the painting survived a tumultuous journey across Europe, including theft by the Nazis during World War II and subsequent recovery by Allied troops. In 2016, the Polish government purchased the work for €100 million, cementing its status as a national treasure currently housed at the Czartoryski Museum in Kraków.

While some earlier scholars misidentified elements of the background as a window, modern analysis has corrected these misconceptions, revealing the painting to be in far better condition than previously assumed. It remains a rare, brilliant example of Leonardo’s mastery, standing alongside the Mona Lisa as one of only four surviving portraits of women by the artist.
