A masterpiece painting, reminiscent of Renaissance depictions of Archimedes, an elderly yet powerful figure, standing atop a rugged cliff at twilight. His ancient Greek robes flow in the wind, and his face is deeply lined with wisdom. A spectral orb above his head glows with golden light, symbolizing his connection to knowledge. Intricate symbols and equations orbit the orb, casting shadows on his face. He cradles a fragile, floating model of the cosmos, with stars, planets, and constellations shifting and rotating slowly. The air shimmers with his mind's energy, and a sunbeam pierces through storm clouds, bathing him in warm, celestial light. The scene blends gentle volumetric lighting with rich contrasts, giving a sense of magical, cerebral aura. Warm, restrained colors emphasize Archimedes' quiet, monumental wisdom, as if he is both human and timeless symbol. "
