Feast of Silenus Sebastiano Ricci (1659-1734)

The picture has something of this: group, people, nude, man, many, woman, reclining, Renaissance, god, baroque, shirtless, sculpture, veil, music, wear, son.
Perhaps it’s a painting of a group of naked men and women in a wooded area with a statue in the background and a red flag in the foreground.
