His very late pieces are very interesting. His piece "Nuages Gris" is often cited as being the first impressionistic piece and his piece "Bagatelle sans Tonalité" presaged Schoenberg's move towards atonality a few decades later. He also received the four minor orders in the Roman Catholic Church (these are porter, lector, exorcist, and acolyte, and are one rank below a subdeacon).
