duchesse de Dorothée Dino, Memoirs of the Duchesse de Dino…
“ On Sundays and great festivals M. de Talleyrand was always present at mass when he was at Valençay; on his two patron saints' days, St. Charles and St. Maurice, he was also present, and would have felt hurt if the vicar had not come to say mass at the Château. His behaviour in chapel 170 was entirely proper, and notwithstanding his infirmity he would always kneel down at the right moment. If there was no mass, if people came late or made a noise, he noticed it as being improper. During mass he read attentively either the Funeral Orations of Bossuet or his Discourse upon Universal History. ”
