How do you present things to children like the ‘Boudiccan revolt’ and the massacres of colonists that took place at Colchester and London in AD 60  – and can it ever be got right? Given we have two written accounts (by Tacitus and, later, Cassius Dio), can we ignore them? Dio pulled no punches in recounting hideous atrocities being carried out on Roman citizen women – their breasts were cut off and sewn to their mouths, and their bodies skewered lengthways – but are these images ‘suitable’ for children?

And already - see? - the subject is fetishised. But remove those accounts, and knowledge and images of annihilation and casualties on all 'sides', and the subject becomes sanitised.
