Redon married later in life at the age of 40, became a father, and lived happily ever after. His search for life's meaning set him on a spiritual path through the studies of Hinduism and Buddhism. I can't think of an artist who better reflects this "change" of heart....his early work is so dark and desperate, these later examples, very light and cheerful.
This book about Redon is available in most public libraries and also in The Museum of Modern Art shop in NYC.
