Sirius is a binary star in the constellation Canis Major and 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.”*
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.
Giulio Magli (1964- ) is an Italian archaeaostronomer 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.
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!
