Calpurnia

 was the wife of Spartacus. She was at his side as he led the uprising against the Roman Empire in the 1st century BC.

Jamie McCrimmon, Ben Jackson and Polly Wright became caught up in the rebellion and helped Calpurnia and Spartacus as much as they could before they had to let history take its course. Polly especially grew very close to Calpurnia. (PROSE: The Slave War)
