Salvator Mundi is a painting of Christ as Salvator Mundi (Latin for “Savior of the World”) by Italian artist Leonardo da Vinci, dated to c. 1500. The painting shows Jesus, in Renaissance dress, giving a benediction with his right hand raised and two fingers extended, while holding a transparent rock crystal orb in his left hand, signaling his role as savior of the world and master of the cosmos, and representing the ‘crystalline sphere’ of the heavens, as it was perceived during the Renaissance.[1][2] Aroun

La belle ferronnière is a portrait of a lady, usually attributed to Leonardo da Vinci, in the Louvre. It is also known as Portrait of an Unknown Woman. The painting’s title, applied as early as the seventeenth century, identifying the sitter as the wife or daughter of an ironmonger (a ferronnier), was said to be discreetly alluding to a reputed mistress of Francis I of France, married to a certain Le Ferron. The tale is a romantic legend of revenge in which the aggrieved husband intentionally infects himself with syphilis, which he passes to the king through infecting his wife.[citation needed]

Leonardo’s Lady with an Ermine, has also been known by this name. This was once believed to be a portrait of Cecilia Gallerani—one of the mistresses of Lodovico ‘il Moro’ Sforza, Duke of Milan.[1] The narrative and the title were applied to Lady with an Ermine when it was in Princess Czartoryski’s collection, and became confused with La Belle Ferronniere by the presence in this image also of a jewel worn on a delicate chain across the forehead, called a ferronnière.

Lady with an Ermine (Italian: Dama con l’ermellino [ˈdaːma kon lermelˈliːno]; Polish: Dama z gronostajem) is a painting by Italian artist Leonardo da Vinci from around 1489–1490 and one of Poland’s national treasures.[2] The portrait’s subject is Cecilia Gallerani, painted at a time when she was the mistress of Ludovico Sforza, Duke of Milan, and Leonardo was in the Duke’s service. It is one of only four portraits of women painted by Leonardo, the others being the Mona Lisa, the portrait of Ginevra de’ Benci, and La belle ferronnière. The painting was purchased in 2016 from the Czartoryski Foundation by the Polish Ministry of Culture and National Heritage for the National Museum in Kraków, and has been on display in the museum’s main building since 2017.[3] Source: Lady with an Ermine – Wikipedia
