The Young Courtesan (1821). Xavier Sigalon (French, 1787-1837). Oil on canvas. Louvre Museum. Sigalon, the son of a poor rural schoolmaster, came to Paris and obtained admission to the studio of Pierre-Narcisse Guérin. He did not agree with the instruction he was given, and tried to train himself by studying the Italian masters in the gallery of the Louvre. In 1822 he exhibited The Young Courtesan, which at once attracted attention and was bought for the Luxembourg.
