In my recent "Marc-Antoine Charpentier compositeur pour les
Jésuites, 1687-1698: quelques considérations programmatiques,"
Bulletin Charpentier, 2001, [since republished in Marc-Antoine
Charpentier, un musicien retrouvé, ed. C. Cessac, 2005], I
noted (p. 8) that, after cahier 64, the "ordinary" compositions seemed
to leap to the "extraordinary" notebooks (that is, from the so-called
"French" notebooks to the "Roman" ones). "En effet," I commented, "tout
se passe comme si, par un souci d'exclusivité, les Jésuites avaient fait
un nouveau marché avec Charpentier au début de 1694, un marché selon
lequel le compositeur aurait promis que, s'il venait à quitter sa tenure
à Saint-Louis, il céderait aux révérends pères les œuvres 'ordinaires'
qu'il ferait désormais à leur intention."
The other day [that is, circa 2002] I was thumbing through some of the notes I took in Rome over a decade ago. And on a little sheet on which I had taken a few notes from the Livre de comptes de la procure de l'Assistance de France, 1680-1715 (AG, 631/A), even though they seemed to tell us nothing about Charpentier, I saw that in 1694 Paolo Lorenzani was paid 106 livres 9 sous: "Au Sr Paul Lorenzani, 106 L – 9."
Judging from the amount of the remuneration, the Jesuits commissioned
a rather important work from the Roman composer in late 1693 or at some
point in 1694. The document unfortunately does not reveal whether this
commission coincides chronologically with the change that can be
discerned in Charpentier's notebooks early in that year. Still, this
payment suggests that if the missing cahier 65 did in fact bring a
modification in Charpentier's "ordinary" obligations at Saint-Louis,
Lorenzani was either involved in the new regimen or else knew how to
take advantage of the situation. One thing I can say with reasonable
certainty: if there were other payments to musicians in that register,
they were such obscure artists that I didn't take notice of them. In
other words, the payment to Lorenzani does not seem to be just another
link in a long chain of payments to a variety of extraordinary
composers, 1680-1715.
