Choose another year from the "Roman" cahiers
Cahiers XX and XXII are missing, and with them disappeared all traces of commissions that Charpentier received for the year 1676. I personally would guess that there was a work for the festivities organized by the Jesuits of Saint-Louis on July 12 at which the harangue was given by Father Verthamon (grandchild of a faithful Guise supporter during the League and uncle of the Talon-Voisins, who were friends of the Charpentier family). Incidentally, several pieces of Jesuit paper are tucked into the middle of cahier 13, just where Charpentier copied out H. 394, suggest that the St. Cecilia oratorio was revived during the 1690s (but not necessarily for the Jesuits, because Mme de Guise was alive until 1696). The presence of this Jesuit paper does of course suggest that the work may have originally been destined for performance in a Jesuit church.
One of the Te Deums that Charpentier includes in his count but that do not seem to have survived, may also have been in these notebooks, to celebrate the capitulations of Aire and Maestricht in August-September. And of course there was the music for La Triomphe des Dames.
