Constant Troyon (French pronunciation: [kɔ̃stɑ̃ tʁwajɔ̃]; August 28, 1810 – February 21, 1865) was a French painter of the Barbizon school. In the early part of his career he painted mostly landscapes. It was only comparatively late in life that Troyon found his métier as a painter of animals, and achieved international recognition.
