"Generate a depiction of Anaximander, the ancient Greek philosopher and early scientist, in a style that reflects his pioneering contributions to cosmology and philosophy. Show him with a thoughtful expression, symbolizing his profound contemplation of the fundamental principles underlying the universe. Include elements such as celestial bodies, geometric shapes, or ancient Greek astronomical instruments to convey his interest in cosmological theories. The image should capture Anaximander's curiosity, intellect, and his role as a visionary thinker in ancient Greece."
