They heard And from His presence hid themselves amoung The thickest trees Gustave Dore (1832-1883)

The picture has something of this: people, tree, group, man, river, nude, two, portrait, monochrome, black and white, three, water, woman, wood, reclining.
Perhaps it’s a man kneeling in the middle of a forest next to a tree with a light coming from the top of it, vintage line drawing or engraving.
