"Terra incognita" - the magic word of longing for discoveries and adventures of past times - in Papua New Guinea it becomes reality, at least for us "Western" people. Skulls of deceased ancestors serve as nightly headrests; bone trophies; skulls of killed enemies decorated with ornaments; the mummy of a village elder protects the village even after his death; women whose knocked-out front teeth show the special affection of their husbands; "Stone-age" tools and weapons, which are not only used ritually; jumping towers up to thirty meters high made of wood and lianas, from which young men fall every year; the jump cushioned by lianas - the archetype of modern bungee jumping - the authors of this volume take us to this world threatened by modern civilization.
