Les Peintures morales,

seconde
partie: de la doctrine des passions : où il es traitté de L'amour
naturel, & de l'amour divin, & où les plus belles matieres de la morale chrestienne sont expliquées - by Pierre Le Moyne.

Publisher: Mauger, François. 1669

A rare example from the 1600s when French binders cut up  old vellum manuscript pages used to strenghten the binding. Normally these books have been taken apart, and the manuscript sold separately - so it is quite rare to see one intact. I have not tried that, also because the book in itself is quite rare and valuable.

 Period calf. Approx. 6 1/2 x 4 1/2 x 1 inches.
