Alexandre Dumas,
Tales of Strange Adventure
(1907)
“ Madame du Barry, all powerful as she was, never dreamt of combating his influence; his name, his position, his wit raised him above attack. During mass the King's thoughts often wandered to the tempest this new escapade of Madame du Barry's would raise, if it were to reach the Dauphin's ears. That Prince had indeed only the day before spoken his mind pretty freely to the Countess, who in spite of his wishes had pushed her nephew the Vicomte du Barry into an equerry's post in his household. ”
