I think this picture relates to retreating to nature in the way that we have an open mind and an open road to travel on when we are out in nature thinking about everything. The road symbolizes the amazing life we have ahead of us.
Artist and feminist activist Barbara Leigh Smith Bodichon, born in 1827 (d. 1891), was a founder of the women's rights/suffrage movement in Britain. She wrote "A Brief Summary, in Plain Language, of the Most Important Laws Concerning Women," which listed for the first time the legal restrictions under which women lived. This book helped move forward the Married Women's Property Act. When she died, a newspaper wrote, "The deceased lady was a militant Radical, but she lived only to do good."
