This motet is Richard Proulx’s arrangement of Joseph Noyon’s Maître de Chapelle de Saint-Honoré d’Eylau à Paris. It is unclear if this copy manuscript was ever published. Proulx wrote two versions. Both include brass, organ, choral, and timpani parts. Version A, however, is written for 3 trumpets and 3 trombones; whereas version B has only 2 trumpets and 2 trombones.
