*The perforation of the nipple to apply jewelry has been practiced by various people throughout history. Male nipple piercing was reported to be done by the Karankawa Native Americans, female nipple piercing is practiced by the Kabyle people in Algeria. In the western world it potentially dates back to the 14th century. The anthropologist Hans Peter Duerr traces the earliest known practice of female nipple piercing as a fashion statement to the Court of Isabeau of Bavaria (1370 to 1435), queen consort of France, quoting Eduard Fuchs he describes that:
…fashion eventually led to the application of rouge to freely display nipples placing diamond-studded rings or small caps on them, even piercing them and passing gold chains through them decorated with diamonds, possibly to demonstrate the youthful resilience of the bosom.
