Barbizon \Bar`bi`zon"\, or Barbison \Bar`bi`son"\, school
\school\ (Painting)
   A French school of the middle of the 19th century centering
   in the village of Barbizon near the forest of Fontainebleau.
   Its members went straight to nature in disregard of academic
   tradition, treating their subjects faithfully and with poetic
   feeling for color, light, and atmosphere. It is exemplified,
   esp. in landscapes, by Corot, Rousseau, Daubigny, Jules
   Dupr['e], and Diaz. Associated with them are certain painters
   of animals, as Troyon and Jaque, and of peasant life, as
   Millet and Jules Breton.
