Étienne Joseph Mathieu Terrus was a French painter from Roussillon.
Terrus was born on September 22, 1857 in Elne, Pyrénées-Orientales. When he was 17 years old, he went to Paris to study but soon after, he went back to Elne, where he produced most of his works.
He used to walk with his easel and he is considered one of the precursors of Fauvism. During his life, he was very much appreciated by artists like George-Daniel de Monfreid, André Derain, and Henri Matisse, who was his penpal from 1905 to 1917.
He died on June 22, 1922 in Elne.
