Portrait of a young thinker, France 18th century

Portrait of a young thinker attributed to the French painter Henri-Pierre Danloux (1753-1809). This Enlightenment thinker looks incredibly similar to Jean-Jacques Rousseau (1712-1778). His outfit, far from being tight, shows the freedom of the wearer. Beyond convention, no wig matches his hair, his silk vest is open, the sleeves of his shirt are rolled up, his scarf is a little loose.
We can also admire the fineness of the lace on its jabot and its sleeves.
Absorbed in thoughts of the work open on his desk His right arm is placed on a second literary work placed itself on emerald-colored silk.
18th century gilded wood frame.
