Create a highly detailed and realistic image of a statue of Marcus Aurelius, depicted as a dignified Roman emperor. The statue should capture his thoughtful expression and regal posture, embodying the wisdom and stoic philosophy he is known for. The background should be minimalistic to emphasize the statue, with subtle lighting that highlights the texture and contours of the sculpture. The statue should be made of bronze, with a patina that suggests age and historical significance. Include a pedestal with classical Roman architectural details to complete the composition.
