On the plate of M. Jules, Baron de St. Genois, is the motto:

“Bon livre d’ennui delivre.”

The following cynical epigram,

“L’homme a dit: ‘Faisons Dieu, qu’il soit à notre image.’
Dieu fut! et l’ouvrier adora son image,”

was placed on his book-plate by the philosophical atheist Sylvain Maréchal, who wrote a work entitled “Fragmens d’un poeme moral sur Dieu,” dated 1781.

David Köning remarks:

“L’Art c’est la vie.
La Nature c’est la mort.”

Whilst Patrice Salin fairly gives himself away:

“Tel que je suis, prends moi.”
