A practice of imprinting various designs, often pictorial, upon the skin by means of coloring matter, e. g. Chinese ink, cinnabar, introduced into punctures made by needles; widely in vogue in past and present times amongst uncivilized peoples, and even to some extent amongst civilized races; like the use of rouge, was mainly for the purpose of ornamentation and for improving the appearance, but also in some cases for religious purposes; reached its highest perfection in Japan, where it seems to have been largely resorted to as a substitute for clothing, and was never employed on the face, feet, or hands; among the South Sea islanders the custom is universal, and is still practised by considerable numbers of the lower-class criminals of Europe.
