Mtanga is by 'some' localised as the god of Mangochi, an Olympus left behind by the Yao in their wanderings.

Finally there arose from the mixture of the Yao with the Tai culture, at a rather later time, the Yüeh culture, another early Austronesian culture, which then spread over wide regions of Indonesia, and of which the axe of rectangular section, mentioned above, became typical.
