We tend to think that it is the exclusive purpose of attire to present us in the best possible way; that is of course only part of the reason behind this massive symbolic language. Another potent reason is the desire, or need to create fear in another person, to make them pay attention and understand instantly that we are not to be trifled with.
In our dim past we did this to maintain our territory, to protect our tribal companions, and children, and to secure whatever food sources we had to hand. And so, we daubed ourselves with colored mud, wore the bones and hides of animals and learned about the power of visual exaggeration. We made of our own faces into masks of terror; and eventually created real masks that enabled us to take that statement much farther.
What will be the next fearful thing, do you think?
