Anyone who has spent any amount of time around tattoo artists or those get tattoos will quickly realize that religious symbolism is always evident. The book of Leviticus states, "Ye shall not make any cuttings in your flesh for the dead, nor print any marks upon you: I am the LORD."
Clearly, there is a prohibition against such activities; however this has not stopped scores of individuals from receiving ink. This, to me, is a very good thing. This rebellion against established doctrine has produced some of the most amazing skin art around. There is always something beautiful when you mix deep personal meaning and great art. This can be seen throughout history. So much of the art, architecture and poetry we enjoy today has roots in religion in one way or another.
Benjamin would state that the aura of an original piece can be lost when it is reproduced. I find no greater evidence against this when the ultimate reproduction is performed for an individual on their skin. The art will continue to provide power - despite its reproduction. Walton claims that art is an expression of our childhood. I have often thought that tattooing is indeed a great expression of our childlike qualities. Who did not adorn their bodies as children with crazy stuff - or draw on their skin?
