"Boy on the Rocks" by French artist Henri Rousseau, also known as Le Douanier (the customs officer), a self-taught primitivism/naivism painter. The painting depicts a young boy sitting on a rocky outcrop by the sea, surrounded by lush foliage and exotic animals. Rousseau often incorporated elements of the jungle and exoticism into his work, despite never having left France. "Boy on the Rocks" is a prime example of Rousseau's unique style, which features flattened forms, vivid colors, and a naive, childlike quality. It is considered a masterpiece of naive art and a symbol of the artist's fascination with the exotic and the unknown.
