Although the general subject area "Bodylore" is often
discussed as it relates to proverbs and metaphors, tattooing traditions
and body piercing could also be considered part of the subject area.
You can visit a tattoo site
and view a few pictures. If you are interested in the history of
tattoos, visit The
Tattoo History Source Book--an anthology of historical records on
tattooing (they also offer links to other tattoo areas on the
Internet). Among the Canela of Brazil, body adornment "enhances
appearance, signals changes in social identity, and expresses
culturally prescribed values," and you can visit a National
Anthropological Archive site that presents background and pictures of
Canela body adornment.
