Britain's history is rich in fiery queens, and the first such heroine, tall with red hair down to her waist, commanding and brave, was Boadicea, warrior leader of the ancient Britons.
She lived at the same time as the emperors Claudius and Nero, and led a surprisingly successful British revolt against Roman rule in AD60-61 (which, for reference, was when St Paul was writing epistles and St Mark composing his Gospel).
She was a notable orator. Her enemies, the Romans, said her voice was strident, but, as Margaret Thatcher found, any woman seeking to establish authority over an assembly of men is open to this accusation.
I did a post on her a long time ago (search for 'Boudica'). The article is rather long and detailed.
Careful searching for the actor, Alex Kingston; she's done some pretty racy things as far as I can tell.
But let me go check again. . . . .
