Is there any evidence that previously the Sun rose in west and set in the east, the reverse of today?
If the sun ever did rise in the west then this would suggest a flipping or reversing of the either the earths rotation or the planets hemispheres.
If this did happen and people survived the reversing earth event then there should be some form of ancient written or oral recording of this event, even if it is just mythology.
Would this have triggered a magnetic reversal or been triggered by one? Would an Earth magnetic field reversal be due to the planet physically flip over?
Evidence for the Sun rising in the west?
Immanuel Velikosvsky in his Worlds in Collision book has investigated ancient records that may show evidence for a reversing of the sun rising and setting. Below are quotes from that book, chapter 5 'East and West'
Egyptian evidence that the sun set in the east?
[Herodus talking to Egyptian priests] four times in this period (so they told me) the sun rose contrary to his wont; twice he rose where he now sets, and twice he set where he now rises.
Pomponius Mela, a Latin author of the first century, wrote: "The Egyptians pride themselves on being the most ancient people in the world. In their authentic annals . . . one may read that since they have been in existence, the course of the stars has changed direction four times, and that the sun has set twice in that part of the sky where it rises today."
The Magical Papyrus Harris speaks of a cosmic upheaval of fire and water when "the south becomes north, and the Earth turns over." In the Papyrus Ipuwer it is similarly stated that "the land turns round [over] as does a potter's wheel" and the "Earth turned upside down."
Harakhte rose in the west
Immanuel Velikosvsky suggests that
Harakhte is the Egyptian name for the western sun ... "Harakhte, he riseth in the west." The texts found in the pyramids say that the luminary "ceased to live in the Occident, and shines,a new one, in the orient." After the reversal of direction, whenever it may have occurred, the words "west" and "sunrise"were no longer synonyms, and it was necessary to clarify references by adding: "the west which is at the sun-setting."
Senmut's tomb and reversed stars
In the tomb of Senmut, the architect of Queen Hatshepsut, a panel on the ceiling shows the celestial sphere with the signs of the zodiac and other constellations in "a reversed orientation" of the southern sky.
