In 1918, Girieud was one of the many painters who returned to naturalism.
Leaving youth behind and anxious to return to some well established basic
principles after the upsetting horrors of war, they tried to express beauty
Girieud, who no longer followed fashionable movements such as surrealism,
was fascinated by that new pursuit. Gradually, as he was influenced by friends
belonging to Gasquet's group, he started choosing antique or religious themes and landscapes and mostly devoted his time and inspiration to the achievement of large mural
decorations or frescos in the manner of the Renaissance masters.
