Prosper De Troyer, born in 1880 in Saint-Nicolas, Belgium, was a versatile artist whose work evolved from realism to neo-impressionism, Brabant Fauvism, and geometric abstraction. Influenced by artists like Eugène Laermans, Jacob Smits, and Malevich, he explored various styles and themes throughout his career. De Troyer was associated with artistic circles like Doe Stil Voort and De Meivisch, and his work reflected a blend of spiritual commitment and a quest for pure art. He interacted with prominent figures like Rik Wouters, Alfred Ost, and Paul van Ostaijen, contributing to the Flemish modernist movement.

Prosper De Troyer was a student at the Mechelen Academy and later came into contact with the Italian Futurists, which influenced his artistic style. In the 1920s, he moved towards constructivist abstraction but returned to classicism and expressionism on the eve of the war.
