(a sci-fi masterpiece by Arnold Böcklin) scene with a knight on a war horse wearing dark composite armor consisting of human plate armor. The knight is dressed in full plate armor, the sword is raised. An alien planet in turquoise and green tones is depicted in the background. Purple and pink nebulae are visible. The horse and knight have high reflectivity, and the terrain below is rocky and desolate, with reservoirs reflecting the bright sky.
