Sustris, Lambert – Nessus en Deianeira, 1540 - 1560 Rijksmuseum: part 1

The picture has something of this: two, water, nude, people, woman, man, reclining, Renaissance, outdoors, mythology, mammal, nature, side view.
Perhaps it’s a painting of a group of naked men and women in a wooded area, with trees and a body of water in the middle of the painting.
