Heemskerck, Maarten van – De doop van Christus, 1560-1565 Rijksmuseum: part 4

The picture has something of this: Renaissance, nude, people, group, saint, woman, man, god, baroque, nymph, allegory, kneeling, aura, son.
Perhaps it’s a painting of a man standing in front of a body of water, surrounded by other people, with a tree in the foreground and a castle in the background.
