Römische Büsten hatten teils austauschbare “Perücken”. Vermutlich damit man nicht jedes Mal eine neue Büste anfertigen lassen muss, wenn sich die Haarmode mal wieder geändert hat.
Hairstyle fashion in Rome was ever changing, and particularly in the Roman Imperial Period there were a number of different ways to style hair. As with clothes, there were several hairstyles that were limited to certain people in ancient society. Styles are so distinctive they allow scholars today to create a chronology of Roman portraiture and art; we are able to date pictures of the empresses on coins, or identify busts depending on their hairstyles.
