Thank you, I had missed this article and it makes for interesting reading!
Somehow the thought of digging up and grinding up the bones of the heroic fallen is somewhat distasteful, but then we have to realise that this is looking at things through 'modern day' conditioning. The archaeological record is often revealing of the hard fact that the lives that our predecessors and ancestors lived was often tough and sometimes relatively short; it was also one in which resources in many shapes of forms - including severed limbs for goodness sake - were of value and had to be recycled.
A lesson from history which will, at the very least, surprise some modern-day re-recyclers, perhaps?
