French fencing treatise attributed by Gelli to de la Pervenchere and printed at Nantes in 1867. Gelli mainly uses the heading to give biographical context connecting de la Pervenchere, the marquis de Valfons, and the Moreau circle. A modern secondary bibliography of French fencing treatises repeats the same Nantes 1867 line; that support is preserved only as a note.
