Maurice was an only child. From an early age, his passions were religion and art. He began keeping a journal in 1884 at the age of thirteen. In 1885 he recorded in his journal his admiration for the colors, candle light and incense of the ceremonies at the local church. He frequented the Louvre, and admired especially the works of Fra Angelico, Raphael and Botticelli. At the age of fifteen he wrote in his journal, "Yes, I must that I become a Christian painter, that I celebrate all the miracles of Christianity, I feel that is what is needed." In 1887 he discovered a new source of inspiration, the works of Puvis de Chavannes.
