Sirius is a binary star in the constellation Canis Major and the brightest star in the night sky and is expected to remain so for the next 210,000 years. In relative terms, it is a near neighbour of ours.
One wild theory speculates that Sirius and our Sun had once been binary partners(i).
Many people of my vintage were first made aware of Sirius when Robert Temple published his bestselling The Sirius Mystery . In which he supported the idea of extraterrestrial influence on human cultural development, citing as evidence, the ‘knowledge’ of the Dogon people regarding the Sirius star system before verification by modern astronomy. This idea has now come under serious attack with the claim that Sirius C does not even exist(a). The controversy is still raging as the Bad Archaeology website demonstrates(b) as well as an article from the Armagh Planetarium website(c). Jason Colavito has also added a few critical comments regarding the knowledge of the Dogon(j). Colavito also reveals(k) that Arthur M. Young (1905-1995), the helicopter pioneer and Robert Temple’s mentor also “believed he had been in contact with extraterrestrials from Sirius who served as the creator gods of Egypt.”
Two decades ago, Laird Scranton wrote in Atlantis Rising magazine(q) that, “the answers to Temple’s mysteries can no longer be reasonably found in the Sirius question itself because the debate has succeeded in casting doubt on so many of Temple’s assertions. However, there are many other fascinating aspects of the Dogon religion and cosmology not entangled in this debate which, due to the continuing glare of the star Sirius, seem to have been overlooked for study. Some of the most promising of these are the Dogon symbols relating to the structure of matter.” and the blub for his book Hidden Meanings  added that “The mythology of the Dogon tribe of Mali describes how their one true god Amma created all of the matter of the universe. But the system defined by these tribal myths bears a striking resemblance to the actual scientific structure of matter, starting with the atom and continuing all the way down to the vibrating threads of string theory. Moreover, many of the Dogon words, symbols and rituals used to describe this structure are a close match for those found in the myths of ancient Egypt and in the daily rituals of Judaism.“
For the ancient Egyptians Sirius, known to them as Sothis, had great importance, as the heliacal rising of Sirius coincided with the summer solstice which heralded the next flooding of the Nile. They also associated Sirius with the goddess Isis.>John deSalvo claims in his list of old pyramid theories(s) that “Several Arabian writers have seen a mystic correlation between the design of the pyramid and the revolutions of Sirius, the judge-god of the dead.”<
A 2008 report from the University of Hamburg said “scientists led by Helmut Ziegert had found remains of a 10th-century-B.C. palace at Axum-Dungur (Ethiopia) under the palace of a later Christian king. There was evidence the early palace had been torn down and realigned to the path of the star Sirius.”(l)
Additionally, it is also suggested that the earlier structure was the palace of the legendary Queen Of Sheba. Today, Axum is claimed by the Ethiopian Church to be the current home of the Ark of the Covenant, a claim given widespread attention by Graham Hancock some decades ago in The Sign and the Seal.
In the 19th century, Theosophists claimed Sirius as having particular esoteric significance. “Blavatsky stated that the star Sirius exerts a mystic and direct influence over the entire living heaven and is linked with every great religion of antiquity.
Alice Bailey sees the Dog Star as the true ‘Great White Lodge’ and believes it to be the home of the ‘Spiritual Hierarchy’. For this reason, she considers Sirius as the ‘star of initiation’.”(m)
Even today, Sirius plays a part in the symbology of Freemasonry, where it is referred to as the ‘Blazing Star’.
Giulio Magli (1964- ) is an Italian archaeoastronomer with a website in English(d) dedicated to the application of the discipline in Egypt. In 2013, Magli proposed that aspects of the Göbleki Tepe site are related to the recent appearance of Sirius in the night sky around 9300 BC(e). Andrew Collins and Rodney Hale argue against this interpretation(f), which is perhaps understandable as they support a linkage with the Cygnus constellation.
A 2004 paper by Magli, on precessional effects in ancient astronomy(g), has recently been applied by Lenie Reedijk to her contention that the Maltese temples were oriented to Sirius.
In 2012, E. A. James Swagger published The Newgrange Sirius Mystery  in which he endeavoured to link Ireland’s most important megalithic site with both an early understanding of precession and the symbology of the Dogon.
Further to the east, in Armenia, Sirius was closely studied by the people of Metsamor at what is claimed as one of the oldest observatories in the world. In a series of six articles(n) by Rick Ney, Metsamor and the ancient site of Karahundj, sometimes dubbed ‘Armenia’s Stonehenge’, whose 204 stones stand near the town of Sissian are fully discussed. The Trip Advisor website(o) offers several enticing images.
Going from the serious to the silly, I note that the late Flying Eagle (1920-2007) and his partner Whispering Wind specified the planet Xylanthia(f) in the Sirius star system as the original home of a visitor who fell in love with an earthling and later became known as Poseidon!
The Wessex Research Group offer more nonsense in a paper by Murray Bruce in which the author endeavours to convince us that there were ancient astronauts, who originally came to Earth from Sirius and are remembered in our mythologies as the Gods, the Old Ones etc. Bruce suggests that these visitors probably inspired the description of the Sumerian god Oannes!(r)
The Sirius Research institute is concerned with the study of binary stars, precession and, of course, Sirius(p).
