After the demise of Lemuria, new races emerged on Atlantis from the surviving ape-like creatures. This led to the Atlantean races, beginning with the black skinned "Rmoahal" and leading to the "copper coloured" Tlavatli, who were ancestor-worshippers, and then the "Toltecs", who had advanced technology including "airships". The Toltecs were succeeded by "First Turanians" and then "Original Semites". These later produced further sub-races, the Akkadians and Mongolians. A group of Akkadians migrated to Britain 100,000 years ago, where they built Stonehenge. The crudity of the design in contrast to Atlantean architecture is explained by the fact that "the rude simplicity of Stonehenge was intended as a protest against the extravagant ornament and over-decoration of the existing temples in Atlantis, where the debased worship of their own images was being carried on by the inhabitants."
