CAU63SH5 Arnold Böcklin (1827-1901)

The picture has something of this: people, nude, water, man, two, woman, tree, river, recreation, portrait, wear, dug-out pool, visuals, group.
Perhaps it’s a painting of a naked man holding a bird next to a naked woman with a bird on her arm and a bird perched on her shoulder, with a tree in the background.
