In her recent article on Charpentier's handwriting and what it suggests about chronology (see my Musing on the subject), Jane Gosine convincingly suggested that this is a copyist's hand. I wondered if this hand, found only on the recto of cahier 1, fol. 1, could be the hand of Monsieur Du Bois, the founder and director of the Guise Music.
While in Paris in January 2008 I checked Du Bois' handwriting BnF, ms. fr. 17052: the handwriting of the text set to music on fol. 1 does not resemble his handwriting. It clearly was someone other than Du Bois who copied out folio 1 recto of cahier 1
