Marie played some part as a cultural patron. Marie was the benefactor of the painter Jean-Marc Nattier, whom she commissioned in 1748 to paint the last portrait she ever sat for, an unusual one as it was informal. It was a success, was printed and sold in prints. It was also her favorite portrait, which she had reproduced to give to friends. She was a great lover of music and painting and the promoter of many artists. She met the castrato Farinelli in 1737, and the young Mozart in 1764, whom she found very charming. During his visit to Versailles, she acted as an interpreter for her spouse and family who did not understand German. Her major contribution to life at Versailles was the weekly Polish choral concerts.
