Nature impresses us. Its color, complexity, and vastness are inspiring. Thomas Cole and Thomas Moran, who were moved by majestic views, saw in the landscape a language for sharing heartfelt emotions and addressing the profound questions of life. Georgia O’Keeffe also responded to beauty and spirituality in nature, but she looked instead to quiet experiences on an intimate scale, painting the delicate petals of an iris. There are many ways to admire nature. The Impressionists responded not just to their physical surroundings but also to the qualities of light and atmosphere that colored them. In his painting of Vesuvius erupting, Pierre-Jacques Volaire offered another perspective from which to celebrate the spectacle of nature: with a fearful respect for its uncontrollable power.
