Create an ultra-realistic marble statue of Marcus Aurelius, seated on an ornate throne adorned with Stoic symbols. One hand holds a scroll representing 'Meditations', while the other gestures thoughtfully. His face should reflect wisdom, with detailed beard curls and lifelike textures. The toga must have natural folds, and the marble surface should display subtle veining. Dramatic lighting should highlight the statue’s intricate details, evoking timeless authority and philosophical depth.
