imperial couple as Mars and Venus

The union of Mars and Venus became so symbolic of Rome that married couples sometimes commissioned statues representing themselves as Mars and Venus. This life-size Roman sculpture, dating from 120-140 CE, originally bore the portrait heads of the emperor Hadrian and his wife Sabina. Later, the head of the woman was changed to a portrait of Lucilla, wife of the emperor Lucius Verus, so that the sculpture could refer to that imperial couple.
