under control—so much so that he exiled his only surviving grandson to the island of Planasia"; Tacitus goes on to call her "a real catastrophe to the nation as a mother, and to the house of the Caesars as a stepmother" and "a compliant wife, but an overbearing mother". Livia's image appears in ancient visual media such as coins and portraits. She was the first woman to appear on provincial coins in 16 BC and her portrait images can be chronologically identified partially from the progression of her hair designs, which represented more than keeping up with the fashions of the time as her depiction with such contemporary details translated into a political statement of representing the ideal Roman woman.
