The name Pelasgians was used by classical Greek writers to refer either to the ancestors of the Greeks, or to all the inhabitants of Greece before the emergence or arrival of the Greeks.
There is also a reference to Occidental Ario (Arian)-Atlanteans. This may be a reference to the initial Arian race which followed the Atlanteans and originated in the Occident or Central Asia (Tibet). They were the origin of the Arian Root Race.
