Caracalla

Caracalla (188–217), formally known as Antoninus, was Roman emperor from 198 to 217 AD. He was a member of the Severan Dynasty, the elder son of Septimius Severus and Julia Domna. Co-ruler with his father from 198, he continued to rule with his brother Geta, emperor from 209, after their father's death in 211. He had his brother killed later that year, and reigned afterwards as sole ruler of the Roman Empire. Caracalla's reign was marked by domestic instability and external invasions from the Germanic people. This bust represents one of his most usual portrayals, with an angry scowl and a sideways look.
