duc de Louis de Rouvroy Saint-Simon, Memoirs of Louis XIV and His Court and of the Regency…
“ Monsieur de Luxembourg was perhaps the only person in France who was ignorant of Madame de Luxembourg’s conduct. He lived with his wife on apparently good terms and as though he had not the slightest mistrust of her. On this occasion, because of the want of dancers, the King made older people dance than was customary, and among others M. de Luxembourg. Everybody was compelled to be masked. M. de Luxembourg spoke on this subject to M. le Prince, who, malicious as any monkey, determined to divert all the Court and himself at the Duke’s expense. ”
