УМОЛЯЮ! переведите текст БЕЗ ПЕРЕВОДЧИКА,умоляююю... The Art of Pleasure
There is not much written about the Maori people before the Europeans came, but from museums and old myths we are able to learn something of their life and the pleasures they enjoyed.
These myths tell us that many years ago the noble Raukataure, wishing to give happiness to everyone, invented the arts of amusement. And the children of Sky-Father and Mother-Earth told their children all the folk-tales and myths. Though they could not write, their unwritten literature existed in stories, in games, dances and in their vocal music.
It was not all lost, for we can discover many of their amusements that kept them happy in their beautiful land of trees and mountains and rivers.
Folkdances are still very popular with Maori people. These dances are always accompanied by songs. The Haka poi dance, for example, is the most graceful . The poi ball generally figures in dances of young girls and women. Their motions are accompanied by a song.
