I was watching Deadliest Warrior and there was a battle between William Wallace and the king of the Zulus and they were debating which would strike the more intimidating figure or inspire the other with menace.
I wondered about this because I'm familiar with some of the horror of white men at encountering black people for the first time, describing them as savages etc. but is there any recorded horror reaction on the part of coloured people from their first contact with white people? I think that either the Japanese or Chinese where horrified by first contact with White Spaniards and may even have crucified some of their priests.
I also remember in history class some amusing pictures of "white devils" blowing out smoke from a culture which never knew of smoking but I dont remember which culture that was.
Its not entirely a racial thing in the example from Deadliest Warrior because the Scots clans, particularly the highlanders were meant to terrify even disciplined soldiers right up to and including their final defeat at Culloden moore.
