Marble head of the emperor Caracalla (211-217)

I scanned this bust at the British Museum using 123D Catch and my iPhone 5S. I wasn't able to capture the very top of the hair so I reconstructed what I could with MeshMixer.

Caracalla was the son of Septimius Seberus. He began ruling with his bother Geta but murdered him after a year. In 212 Caracalla granted citizenship to all freeborn people in the Empire. In 217 he was murdered (whilst relieving himself,) during a campaign in the East, by an officer whose brother he had executed.
