Eager to know a bit of body piercing history?
The Aztecs, Mayans and various American Indians pierced their tongues as part of their religious rituals. They believed it brought them closer to their Gods as a type of ritual blood-letting. These were warrior tribes, thus practised septum piercing to appear fiercer to their enemies. Similarly, some tribes in New Guinea and the Solomon Islands would pierce their tongue. Common materials used were bone, tusks and feathers.
In the picture, this old Mayan painting found in the Chiapas State in Mexico shows a lady performing a tongue piercing ritual.
