The plaster copy depicts Emperor Tiberius (42 BC—37 AD). The oak wreath (corona civica) was originally given to those who saved the life of a Roman citizen in battle. From Augustus’ reign it became the symbol of imperial power and the exclusive attribute of the ruler: it symbolized the emperor being the only person capable of saving Roman citizens. The original portrait was made in bronze by an unknown Italian sculptor some time between 1500 and 1800. It was modelled on Tiberius portraits from the imperial period. The facial features and the locks over the forehead, which are parted in the middle as a swallow tail, evoke the latest portrait type of Tiberius from antiquity.
