Tattooing for women began when they reached physical maturity, after menstruation, at about age 20. Historically, men received their first tattoo after killing their first animal, an important rite of passage. Sometimes tattoos signaled social class. For example, the daughter of a wealthy, famous ancestor or father would work hard at her tattoos to show the accomplishments of that ancestor or father. They would sew, or prick, different designs on the chin, the side of the face, or under the nose.
