Across Papua New Guinea the cassowary is considered by most tribes to be an androgynous animal and a hemaphrodite and in fact male cassowaries are not believed to exist.
A belief that is widespread throughout the Sepik region of the country and present in the mythology of tribes such as the Boiken, Abelam, Arapesh and Paraik is that the world was in fact created by a cassowary who was also the mother of humanity.
The cassowary as a fierce mother goddess played a symbolic role in intitiation ceremonies that existed for young men in many tribes :
"Briefly, the cassowary symbolically devours the preadult novice, and then disgorges him, or gives birth to him, as an adult."
Such ceremonies incorporated the symbology of this bird and were designed to test the courage and mettle of young men before they could take on the mantle of becoming a warrior:
"Part of the ritual, throughout a great part of the Sepik area, was (perhaps is) the drawing of blood from the novice in order to eliminate from his body the "weak" or "bad" blood contributed by his mother during gestation. There were various ways of going about this; the best known way, because it was highly conspicuous, is the patterned and often very extensive scarification practiced by the middle Sepik River groups"
Some initiation ceremonies were truly agonizing:
"The most common procedure, however, appears to have been the drawing of blood from the penis"
The cassowary mother therefore played her part as a harsh and exacting mother goddess in judging of the worth and value of a young man as she oversaw the scarification rites which were performed by men impersonating her armed with sharpened cassowary bones:
"A number of methods were used, some of them carried out with cassowary bone implements. Actual bone daggers were used by the Boiken at the second stage of initiation. It is clear that during initiation not only was the whole process symbolic of "devouring," but the operators themselves to some degree impersonated the cassowary. To give a few instances, the (Nagum) Boiken initiator was actually termed amia, the "female cassowary"
As such the cassowary mother goddess figuratively through such initiation ceremonies was believed to continue to give birth / create young warriors with the ferocity of the bird itself:
"These few examples hint, even if lamely and disjointedly, at this extraordinary creature's role in Sepik life and imagination. To sum up, the cassowary in myth is the maker of men and their world. Men in turn become cassowaries in ritual and, generation by generation, replay the cassowary's role in creation. Besides, the cassowary not only "makes" men; it has the qualities of aggressiveness a Sepik man desires for himself."
A man who had become a warrior could then arm himself with amongst other weapons a stilleto sharp dagger made from the bone or toe of a cassowary with which he might dispatch his enemies in war.
