"Nothing makes me so happy as to observe nature and to paint what I see. " - Henri Rousseau
This image I posted at @Madhatters was inspired by some of Rousseau's "women in exotic forests" paintings.
Rousseau painted jungles ,forested and exotic landscapes even though he never left Paris.
He claimed to have had "no teacher other than nature".Essentially he was self-taught and is considered to be a naïve or primitive painter.
