My view of all of this is 'maybe Marilyn Manson got his inspirational look from the the people who took on these representations long ago?' I don't think the question of 'authenticity' should be the matter. I think the representation of 'what it meant' is more important. Much has been lost through the decades, centuries due to the mass slaughter of not only different peoples here but their languages, their everyday way of life, their very being in the ambitious attempt by foreigners to make extinct forever the original 'anything' of people in this country alone. Not to make a bold statement here but when looking at things in such detail here one can see why a lot of things today are always in question in regards to the Indigenous. In many cases also some of those Indigenous peoples themselves may be just as confused. Very few know exactly what something like this may or may not mean. I for one think Johnny is sincere in trying to get it right whether it is correct or not in peoples views. But you also have to take into consideration that those people long ago, even as a people, as a family had their own slight individual looks and meanings that were given to them. Look for meaning in things and less in 'authenticity'. This includes one's own view.
