Cartimandua, was she a traitor queen? [audio 9min]

Cartimandua was a Celtic Queen who lived at the same time as Boudicca but, unlike her famous counterpart, she's largely forgotten. She ruled much of northern England and formed a controversial alliance with the Romans, designed to keep them from invading her kingdom. Seen as traitor, she was never romanticised by Britons quite like the rebellious Queen Boudicca. Barbara Erskine has written a novel about Cartimandua, Daughters of Fire (Harper Collins), and Dr James Fraser from Edinburgh University is an expert in Celtic history.
