Hylas and the Nymphs John William Waterhouse (1849-1917)

The picture has something of this: people, woman, group, child, girl, water, tree, mammal, nude, man, two, river, nymph, outdoors, recreation.
Perhaps it’s a painting of a group of naked women in a pond surrounded by lily pads and water lilies, with a man kneeling down to the side of the painting.
