A crobylus is a hair bun, mainly seen in the iconography of the historical period, on women and more rarely men. The distinctive “melon” hairstyle, with evenly divided curled braids drawn back into a tight crobylus, was an appropriate choice for sculptures of young women and girls from as early as the Classical period. In Roman times this coiffure regained its popularity, mainly due to its use in portraits of Plautilla, briefly (202-205 AD) the wife of the Emperor Caracalla.
