In 61 A.D. BOUDICA (AKA Boadicea, Bunduica, Voadicia, Bonducca,
Boudicca or Boudicea) led Britain in a revolt against the Roman Empire.
She refused to live in an unnatural world dominated by such criminals.
"Boudicca" is the form given by Tacitus and is
the only contemporary rendering of the name. On philological evidence,
however, the spelling probably should be "Boudica"; a variation
of "victory" in Celtic and the equivalent of the modern "Victoria".
In any event, "Boadicea" is incorrect. (Encyclopedia Romana)
