"The one who operates on himself with a tattoo performs a direct aesthetic operation, moreover he always operates driven by experience that leaves a mark on an emotional level, whereby the tattoo becomes the visible and indelible representation of emotional states happened or desirable, with which the subject wants to be always in contact. This operation is done by man on man, considering his own body as a support that enters into total and permanent symbiosis with the images above tattooed, indeed a mutual identification takes place in addition..."(Plinio Martelli, 1980)
