The Tribe That Knew the Invisible Star
High on the Bandiagara Escarpment in Mali, West Africa, the Dogon people have lived for centuries in harmony with the rhythms of the cosmos. Their villages cling to the cliffs like eagle nests, their lives governed by intricate mythology and precise astronomical observation. For generations, they have celebrated the Sigui festival, a sacred ceremony held every 60 years (or approximately 50 in some calculations), involving elaborate masks, dances, and retellings of their creation story.
At the heart of this cosmology is Sigi Tolo, the star of Sigui, known to us as Sirius A, the brightest star in the night sky. But the Dogon speak of a companion star they call "Po Tolo", it's small, incredibly dense, and orbits Sirius every 50 years. They also describe it as made of "sagala," a metal heavier than all Earth iron, and white in color.
"The Dogon have a knowledge of Sirius B which is quite extraordinary."
– Marcel Griaule
Sirius B, a white dwarf companion to Sirius A, was first inferred in 1844, confirmed in 1862, and photographed only in 1970. Its density is extraordinary with a teaspoon of it weighing many tons. Its orbital period is exactly 50 years, and it is invisible to the naked eye.
So, just how did an isolated African tribe possess this knowledge centuries before modern telescopes revealed it?
The French Anthropologists Who Uncovered the Impossible
In 1931, French ethnographer Marcel Griaule arrived among the Dogon with his colleague Germaine Dieterlen. Over two decades, they immersed themselves in Dogon culture, earning the trust of the Hogon priests and elders.
In 1946, the blind priest Ogotemmêli spent 33 days revealing sacred knowledge to Griaule. He described the Sirius system in great detail, including Po Tolo's density, orbit, and invisibility.
Griaule and Dieterlen published findings in journals and *Le Renard Pâle* (1965). They documented Dogon knowledge of:
- Sirius B's 50-year orbit
- Its extreme density ("heaviest star")
- A third star in the system (Sirius C, debated but possible)
- Jupiter's four major moons
- Saturn's rings
- Earth's rotation and revolution
Robert Temple's 1976 book *The Sirius Mystery* brought the case to global attention, proposing extraterrestrial contact...
Robert Temple's The Sirius Mystery (1976): The Book That Ignited the Debate
In 1976, British researcher Robert K. G. Temple published *The Sirius Mystery*. A book that would forever change how the world viewed the Dogon tribe's astronomical knowledge. Temple, then in his early 30s, had stumbled upon Marcel Griaule and Germaine Dieterlen's ethnographic work while researching ancient mythology. What he found stunned him: an isolated African tribe possessing detailed information about the Sirius star system that modern astronomy had only confirmed decades earlier.
Temple's central thesis was bold: the Dogon could not have acquired this knowledge through normal means. He proposed direct contact with extraterrestrial visitors from the Sirius system thousands of years ago, beings the Dogon called the Nommo. The book became an instant sensation in alternative circles, selling hundreds of thousands of copies and inspiring generations of ancient astronaut theorists. Temple argued the Nommo were amphibious, fish-like entities who arrived in a spinning ark, taught civilization, and returned to the stars.
Key claims from *The Sirius Mystery*:
- Dogon knowledge of Sirius B predates Western discovery
- Descriptions match white dwarf characteristics (density, orbit)
- Parallels in ancient Sumerian, Egyptian, and Greek myths about "fish-men" teachers from Sirius
- Possible connection to Oannes of Babylonian legend
Temple's most famous passage:
"The Dogon have a knowledge of Sirius B which is quite extraordinary. They know that it is a small, dense, white star which orbits Sirius every fifty years. They call it the 'seed' star and say it is the heaviest star."
– Robert Temple, The Sirius Mystery
Another key quote:
"If the Dogon were told about Sirius B by a visitor from outer space, then that visitor must have come from the Sirius system itself."
– Robert Temple
Temple connected Dogon mythology to ancient Mediterranean "fish-god" figures like Oannes (who taught Babylonians writing and laws) and suggested a shared extraterrestrial origin. The book faced fierce criticism. Skeptics accused Temple of cherry-picking data and ignoring cultural contamination possibilities.
Yet *The Sirius Mystery* endures as one of the foundational texts of ancient astronaut theory, influencing Erich von Däniken, Graham Hancock, and modern discussions of prehistorical contact. Temple stood by his work until his death in 2024, maintaining the Dogon knowledge remains unexplained by conventional means.
The Nommo: Teachers From the Sirius System
Dogon mythology centers on the Nommo, the amphibious beings from the Sirius system who descended in a spinning "ark" that made fire and noise. They landed in water, taught humans agriculture, metallurgy, weaving, and astronomy, then returned to the sky.
The Nommo are depicted as half-human, half-fish, living in water yet walking on land. They are androgynous, and associated with fertility and creation.
Ogotemmêli told Griaule:
"The Nommo divided his body among men to feed them. That is why it is also said that as the universe 'had drunk of his body,' the Nommo also made men drink. He gave all his life principles to human beings."
– Ogotemmêli to Marcel Griaule
Sigui celebrates the Nommo's visit and the revelation of speech and knowledge.
The Debate: Ancient Knowledge or Cultural Contamination?
Skeptics argue Griaule/Dieterlen contaminated the data. Sirius B was known to astronomers since 1862. Some Dogon may have learned from Europeans or missionaries.
Critics like Walter van Beek (1991) claimed inconsistencies in Dogon knowledge and suggested Griaule projected his own ideas.
Defenders note:
- Dogon described Sirius B before 1970 photo
- 50-year cycle predates Western contact
- Knowledge restricted to initiated priests, preserved orally
- Recent studies find consistency across generations
The debate continues wit hthe same passion today in 2025. Was it contamination or was it genuine ancient tradition?

Final Verdict
THE STAR PEOPLE THAT TAUGHT A TRIBE ITS SECRETS. The Dogon knew Sirius B's invisible dance centuries before telescopes confirmed it. The Nommo came from the water and sky, bringing their knowledge with them and sharing it with the Dogon people freely. Contamination or contact, the mystery endures to this day. The Dogon themselves stated the oral traditional stories were told for a long, long time before Europeans arrived. I have absolutely no reason to not believe the Dogon people are anything other than being 100% honest. What do you think?
