Paysage avec deux nymphes et un serpent 

This landscape painting by Nicolas Poussin, depicts a serene and idyllic scene with a river winding through a lush forest. In the foreground, two nymphs recline on a rocky ledge, their serene postures contributing to the tranquil atmosphere. The background features a distant, almost mythological, castle, adding a touch of mystery and grandeur to the composition. Poussin's skillful use of light and shadow, along with his meticulous attention to detail, creates a sense of depth and realism, making the viewer feel as if they are standing within the painting itself.
