Most likely, the very first tattoo happened on accident. All it
takes is a few rowdy primitives playing around the fire. It
wouldn’t take long for someone to fall in, get poked with a
charred stick and later heal before they’d realized that they
were on to something. The news probably spread as fast as the
fires that prompted the invention. As a matter of fact, it is
rumored that the first tattoos were of the sun or flames in
honor of the sun god(s).
There were three major factors that took the practice of tribal
tattooing from the realm of art and into the plane of the
spiritual: Pain, Permanence and Loss of the Life Source (blood).
This mystical trio elevated the tattoo from mere art and
transformed it into a chance to draw people into a relationship
with God, a god, magic powers, or a trance or vision state.
