"This is not a cave."
Garde la Foi, mes amis! Nous nous sommes les sauveurs de la République! Maintenant et Toujours!
(Keep the Faith, my friends! We are the saviors of the Republic! Now and Forever!)

Thanks for the correction! I misread the font on the original.
There was a number of people on DU yesterday yelling "This is not a cave!" and it reminded me of the Magritte's pipe.
