The Dongon

We publish an interesting article Eng Joseph Merlino taken from his blog giuseppemerlino.wordpress.com.
Sirius is the brightest star in the night sky. It belongs to the constellation Canis Major. It is located at a distance of 8.6 light years from Earth and is therefore one of the stars closest to us.
An African population has an interesting oral tradition relating to this star:The Dogon are a people of Mali, a country in west central; are about 240,000, live in a mountainous area within the loop of the Niger, the Bandiagara Escarpment, a UNESCO Heritage Site area.In their oral traditions they speak of the star Sirius, and especially of his companion, Sirius B, revealing knowledge of astronomy that would possess more than 5000 years ago. In fact, Sirius is a binary system and Sirius B is not visible to the naked eye: it can be seen only with a telescope. Sirius B is a white dwarf that orbits the main star at a distance of between 8.1 and 31.5 astronomical units, with a period of about 50 years. It was the first white dwarf to be discovered in 1862 by Alvan Clark, son of the American scholar and manufacturer of lenses for telescopes Graham Clark.But the Dogon how they knew of the existence of Sirius B, which, although much smaller, is more massive than Sirius A, the fact that they called Po (a cereal high specific gravity)?Historically, many cultures have given a special significance to Sirius. She was worshiped in Egypt long before Rome was founded, and many temples of the ancient Egyptians were constructed oriented so that the light from the star could illuminate their inner altars. The Egyptians also based their calendar on the heliacal rising of Sirius, which occurred just before the annual flooding of the Nile and of the vernal equinox.The Dogon celebrated every 60 years, a ceremony that refers to the end of a rotation of Sirius B around Sirius. This population was studied by French anthropologists Marcel Griaule and Germaine Dieterlen for several years from 1931 onwards. During these studies the Shaman Ogo Temmeli drew on the sand the ellipse that Sirius B walked around Sirius and the exact position that Sirius had the ellipse. We now know, however, that the period of rotation is about 50 years, in any case concordances are amazing. This Shaman revealed to the two scholars that the Dogon had settled in Mali for over 500 years but that their real origin was Egypt.
At the end of each ceremony, the Dogon built a mask and masks were found 6, plus the remains of the other two, which would date back to 480 years before the knowledge of the Dogon of Sirius B that the modern Astrophysics discovered only in 1862 recognizing only in 1925 that it was a white dwarf.In the mythology of the Dogon it is also talk of mysterious beings from the star system Sirius called Nommo.
