Cecilia Gallerani (Italian pronunciation: [tʃeˈtʃiːlja ɡalleˈraːni]; early 1473 – 1536), born in Siena, Republic of Siena, was the favourite and most celebrated of the many mistresses of Ludovico Sforza, known as Lodovico il Moro, Duke of Milan. She is best known as the subject of Leonardo da Vinci's painting The Lady with an Ermine (circa 1489). While posing for the painting, she invited Leonardo, who at the time was working as court artist for Sforza, to meetings at which Milanese intellectuals discussed philosophy and other subjects. Cecilia herself presided over these discussions.
