Let us look more closely at the ancient Egyptian mythology relevant to the Dark Star Theory, and explore the mythology central to an understanding of that sacred part of the sky, the Duat. In doing so, it will become clear why I have proposed that this sacred area of the sky dominated by Sirius and Orion marks the perihelion passage of Nibiru. http://www.darkstar1.co.uk/ds7.html Egyptologists point to the heliacal rising of Sirius during the Pyramid Age being coincidental with the summer solstice and the flooding of the Nile. But this symbolic coincidence does not necessarily explain the ancient importance attached to Sirius. The timing of the flooding of the Nile tended to vary, and the heliacal rising of Sirius wasn't necessarily a strong indicator of the coming Nile flood. But there is a more important point here; the Isis/Osiris/Horus mythology predated the Pyramid Age considerably, and represented the most ancient of Egyptian mythology. As one goes back in time, then the precession of the equinoxes take the heliacal rising of Sirius further away from the solstice, occurring earlier in the year as you go back further in time. Therefore, the more ancient source of this mythology cannot have arisen based upon the Nile flood timing, or indeed the Summer Solstice, because these religious notions pre-date this calendrical coincidence The statement above present a problem for biblical redaction which bases its revisions on ancient Egyptian chronology. The further one pushes back dates in attempts to correlate events in the bible, the further back in time specific events in the Egyptian chronology occur. In this context I have no own "theories". In term of the biblical "Noah's Ark", this "ark" is a reference to the Ark of Ra, or what is explained as the Duat. It is not an actual boat used to travel during a historical flood on earth, but an "Ark" which in ancient Khemetic texts describes the path of the Duat. Secondly, the biblical "sons of Noah" are stellar references to the Star System Sirius A, B and C. This brings me to identify the source of the story related to the biblical "flood". "For lo! I wish in my heart to destroy utterly that which I did create. All the world will become a waste of water through a great flood, as it was at the beginning, and I alone shall be left remaining, with no one else beside me except Osiris and his son Horus. I shall become a small serpent, invisible to the gods. To Osiris will be given power to reign over the dead, and Horus will be exalted on the throne that is set on the island of fiery flames." This information is contained in ancient Khemetic (i.E. Egyptian) texts which are more than "instructions for the dead". These texts are guides the science of African astronomy and Cosmology and help to explain how our ancestors viewed the universe, and their origins, before manifesting on earth in the physical realm.
