Cecilia Gallerani, a young woman of Milanese bourgeois background, is depicted with an ermine resting against her torso. Known as the favoured consort of Ludovico Sforza, Duke of Milan, she is rendered with a composed expression, her gaze directed beyond the frame. The ermine, long associated with notions of purity and virtue, reinforces the portrait’s symbolic undertones. Leonardo da Vinci’s adept manipulation of chiaroscuro and his precise attention to anatomical accuracy convey both the sitter’s elegance and a deeper psychological dimension. Acquired in the early nineteenth century by Prince Adam Jerzy Czartoryski, the painting entered the Czartoryski Museum’s collection. Though confiscated by Nazi forces during the Second World War, it was later recovered, restored, and reinstated within Poland’s national heritage.
