In West Africa, specifically Mali, lives a tribe of people called the Dogon. The Dogon are believed to be of Egyptian decent and their astronomical lore goes back thousands of years to 3200 BC. According to their traditions, the star Sirius has a companion star which is invisible to the human eye and this companion star has a 50 year elliptical orbit around the visible Sirius and is extremely heavy. It also rotates on its axis. Two French anthropologists, Marcel Griaule and Germain Dieterlen recorded it from four Dogon priests in the 1930's. How did a people who lacked any kind of astronomical devices know so much about an invisible star? The star, which scientists call Sirius B, wasn't even photographed until it was done by a large telescope in 1970.
The Dogon stories explain that also. According to their oral traditions, a race people from the Sirius system called the Nommos visited Earth thousands of years ago. They also appear in Babylonian, Accadian, and Sumerian myths. The Egyptian Goddess Isis, who is sometimes depicted as a mermaid, is also linked with the star Sirius.
The Nommos, according to the Dogon legend, lived on a planet that orbits another star in the Sirius system. They landed on Earth in an "ark" that made a spinning decent to the ground with great noise and wind. It was the Nommos that gave the Dogon the knowledge about Sirius B. The word Nommos is derived from a Dogon word meaning "to make one drink." The Nommos are usually described as amphibious, hermaphroditic, fish like creatures. The Nommos are also referred to as "masters of the water", "the Monitors", and "the Teachers."
How does one explain a 400-year old Dogon artifact that apparently depicts the Sirius configuration nor the ceremonies held by the Dogon since the 13th century to celebrate the cycle of Sirius A and B ? How does one explain how the Dogons knew about the super-density of Sirius B, a fact only discovered a few years before the anthropologists recorded the Dogon stories ?More on the Dogon tribe in posts to come.
