Marcus Aurelius on horseback, AD 164-166. This is the only complete bronze equestrian statue to have survived from antiquity. It was believed to be a statue of Constantine in the middle ages, so it was not melted down and reused. However, the head has been identified as Marcus Aurelius'. The statue is an example of naturalism, and the contrast of texture between skin and curly hair favored during Antonine rule. Originally, it was gilded.
