The Cool Lunch Table

Qui peut-on identifier ? L'eau-forte de Jean Huber (reproduite aussi par l'exposition de la BNF) est censée représenter : Voltaire (1), le père Adam (2), l’abbé Maury (3), d’Alembert (4), Condorcet (5), Diderot (6) et La Harpe (7) 

From what I can gather, this painting is by Jean Huber and is called "The Dinner of the Philosophes."  Don't hold me to that translation, though.  In each version, Maury is seated on the far left and is sharing the meal with Diderot, Voltaire and Condorcet among others.
