1. Like Bourdelle, Denis had collaborated with Auguste Perret on the 1911-13 Théâtre des Champs-Élysées in Paris. Perret had originally asked the Italian futurist painter Gino Severini to propose designs for Notre-Dame du Raincy's stained glass. Severini, a member of the Art et Liberté group of Parisian artists that Perret cofounded in 1916, embarked on this task in the summer of 1922, but Denis later replaced him.
