Lagrené Louis-Jean-Francois (Paris 1725-1805) – Mars and Venus, an allegory of the world (85x75 cm) 1770 J. Paul Getty Museum

The picture has something of this: people, nude, reclining, woman, wear, curtain, opera, bed, theatre, calamity, performance, Renaissance, furniture, theater, man.
Perhaps it’s a painting of a naked man and a naked woman laying on a bed in a room with green drapes on the sides of the drapes.
