The "Dreamtime", the mythological past, was the time when spirit ancestors travelled thoughout the land, giving it it's physical form, and setting down the rules to be followed by the Aboriginals. Beings such as the "Fertility Mother," the Great Rainbow Serpent, human and animal totemic spirits, and even sky-heroes, survive in stories and ceremonies that have been passed down from generation to generation in song, dance and art. In age-old ceremonies Aboriginal men enacted the lives and activities of these creators of the physical world, it's human and animal inhabitants, plant life, and tribal customs. For Aborigines, the natural landscape has its own beautiful spirit that will never change, and in Dreamtime, they share this spirit with the land.
