Philippe de Champaigne (26 May 1602 - 12 August 1674) was a Baroque era painter of the French school.Source Wikipedia
Born in Brussels of a poor family, Champaigne was a pupil of the landscape painter Jacques Fouquières. In 1621 he moved to Paris, where he worked with Nicolas Poussin on the decoration of the Palais du Luxembourg under the direction of Nicolas Duchesne, whose daughter he married.
After the death of his protector Duchesne, Champaigne worked for the Queen Mother, Marie de Medicis, and for Richelieu, for whom he decorated the cardinal's palace, the Dome of the Sorbonne church and other buildings. He was a founding member of the Académie Royale de Peinture in 1648.
Later in his life (1640), he came under the influence of Jansenism. After his paralysed daughter was allegedly miraculously cured at the nunnery of Port-Royal, he painted the celebrated but untypical picture Ex-Voto de 1662, now in the Louvre, which represents the artist's daughter with Mother-Superior Cathérine-Agnès Arnauld.
