For those who haven't seen it, this is former Python Terry Jones in fighting form from his 2006 series, The Barbarians. Historical Revisionism at it's best and most necessary.
For example when Julius Caesar tells us that he fights in defence of the Celts, he is busy killing over a million of them at his own estimate and forcing another million into slavery. Jones demonstrates that his wars against the Celts were in fact resource wars, fought literally for gold, which the 'savages' had in fact been mining at over 400 sites across Europe and which the empire badly needed to pay it's bills.
More than that, the modern sense of words like Barbarian, or Goth have preserved the negative associations the Romans gave them. The Roman mythos is a story of massive self deception and savagery. On rare occasions when Roman writers allowed themselves a moment of reflection, the sudden change of tone is breathtaking.
They plunder, they slaughter, and they steal: this they falsely name Empire, and where they make a wasteland, they call it peace.
Questions such as, why there are no great Roman mathematicians are central to the story. Rome stole or appropriated many or most of it's technical innovations and destroyed innumerable others, if they had been successful in their efforts to 'civilise' the world, all evidence of human achievement for six millennia before would almost certainly have been lost and without them, perhaps the cause of civilisation might have advanced beyond our dreams.
