Much has been written about the Dogon tribe and their knowledge of the stars. Such a simple people, kept out of the industrial age even today. How did they come by this information? It has been surmised that they were visited by aliens from Sirius, from the constellation of the Dog, due to their descriptions of their visitors, but this is fancy. Their visitors hailed not from Sirius, but from the 12th Planet, who even then had advanced knowledge of the stars as they plotted their travels by them so as to know their place out in space just as ancient mariners held to the stars to know what place they occupied on the vast oceans. The dog heads worn as masks by these visitors were a common ploy, occasionally switched for the heads of birds or snakes. While under the influence of those in the Service-to-Self orientation, they found these masks aided them in terrifying the diminutive humans they encountered, as their expressions could not be read.
