Illustration for Long’s novel Daphnis and Chloe4 Konstantin Andreevich Somov (1869-1939)

The picture has something of this: people, outdoors, tree, man, lifestyle, water, two, leisure, nude, nature, recreation, woman, girl, relaxation, happiness, enjoyment, summer, love.
Perhaps it’s a painting of a man and a woman laying on the ground in the grass next to a tree and a body of water in the foreground.
