Today the Mundurucu are peaceful rubber collectors, but in the 18th century they are the most feared tribe of the jungle. They are a nightmare for both the Portuguese settlers and the neighboring tribes. In the event of a raid, they kill all men and women and cut off their heads. The children are spared and adopted. The heads of their most formidable enemies receive special treatment. They are dried over a fire and then put on poles around the village. The Mundurucu fear the revenge of the spirits of their slain enemies. They protect themselves by tattooing the entire body with vertical stripes.
