The Cygnus identify with the Cygnus constellation.
Andrew Collins traces Cygnus lore back to 15,000 BCE, when Deneb, the brightest star in Cygnus, was the Pole Star. At that time, Paleolithic ancestors practiced religious rituals in deep earth—caves where bird-imagery art has been found by anthropologists.
As early as Palaeolithic times, the stars of Cygnus, was represented by the Swan—the ultimate expression of a widespread belief in the bird as a symbol of the soul. It was seen as the gateway to heaven. Shamanic journeys, Native American funeral rites, the alignments of prehistoric standing stones, all pointed the way to this sky-world, accessed via a cosmic axis.
Collins proposes that the Cygnus Mystery was a dramatic rise in cosmic rays reaching Earth. They provide evidence that the rays, which left subatomic traces in those same deep caves, emanated from a binary star system known as Cygnus X-3.
Collins explains that in 2005, a U.S. think tank went public with its own conviction that a binary system producing powerful jets of cosmic rays triggered a rapid acceleration in human evolution during the last Ice Age.
