The shepherds of Arcadia (Et in Arcadia ego) Nicolas Poussin (1594-1665)

The picture has something of this: Renaissance, people, nude, reclining, saint, two, god, man, baroque, woman, group, Mary, sculpture, three.
Perhaps it’s a painting of a group of people in a wooded area with a man on the ground in the foreground and a woman on the other side of the painting.
