EiU, p 146 (and referred to on p 202):The observation was made on clay fired in kilns by the Etruscans and Greeks. The position of the ancient vases during firing is known. They were fired in a standing position, as the flow of the glaze testifies. The magnetic inclination or the magnetic dip of the iron particles in the fired clay indicates which was the nearest magnetic pole, the south or the north.
In 1896 Giuseppe Folgheraiter began his careful studies of Attic (Greek) and Etruscan vases of various centuries, starting with the eighth century before the present era. His conclusion was that in the eighth century the earth's magnetic field was inverted in Italy and Greece. Italy and Greece were closer to the south than to the north magnetic pole.
P.L. Mercanton of Geneva, studying the pots of the Hallstatt age from Bavaria (about the year -1000) and from the Bronze Age caves in the neighborhood of Lake Neuchatel, came to the conclusion that about the tenth century before the present era the direction of the magnetic field differed only a little from its direction today, and yet his material was of an earlier date than the Greek and Etruscan vases examined by Folgheraiter. But checking on the method and the results from Folgheraiter, Mercanton found them perfect.
An ancient vase found by F.A. Forel in Boiron de Morges, on Lake Geneva, was broken and its pieces were scattered and lay in all directions; when assembled, they all showed one and the same magnetic orientation, which proves again that the magnetic field of the earth was unable to change the orientation originally acquired by the clay when fired and cooled in the kiln.
Large changes of the earth's magnetic fields in historical timesBy measuring the magnetic properties of bricks and other accurately dated human artifacts, geophysicists can reconstruct the history of the local magnetic field. Near Loyang, China, the field was as much as 54% higher in 300 A.D. than it is now. It was 15% higher in 1500 A.D. In 1000, it was less than today's value.

Comment. Direct measurements of the earth's field go back only a few hundred years, but they are consistent with the data reconstructed from artifacts, both showing a steady decrease since 1500. No one has estimated the effects of these substantial changes on radiocarbon dating and, perhaps, human biology.
"Earth In Upheaval", Immanuel Velikovsky, p 133Most interesting is the discovery that the last time the reversal of the magnetic field took place was in the eighth century before the present era, or twenty-seven centuries ago. The observation was made on clay fired in kilns by the Etruscans and Greeks.

These researches, continued and described in a series of papers by Professor Mercanton, presently with the Service Meteorologique Universitaire in Lausanne, show that the magnetic field of the earth, not very different from what it is today, was disturbed sometime during or immediately following the eighth century to the extent of complete reversal.

9 Manley speaks of "the possibility of its [earth's magnetic field] reversal in historical times, 2500 years ago, to be cleared up by more research." However, the more exact date is, according to the original works of Folgheraiter and Mercanton, the eighth century before the present era, or shortly thereafter.
I am not saying it is aliens.....
I had no idea there was a field of study devoted to Barbra Streisand and Madonna.
Good to see you back, I’ve always appreciated your posts.
BTW, you once did an article on blond blue eyed horsemen from North Africa. I was thinking about it a few months ago, but couldn’t find it. Any chance you might repost?
Welcome back.
I think Congress should p[ass a law against any flipping.
Just as white is the new black, south will be the new north.
Wonder if the Czechs will be taken, too?
Why is only Poland impacted?
But what about Guam?
Why doesn’t anyone care about Guam?
It could flip, too!
Is this because of Black Panther?
I’ve always wondered what is happening to the earth’s balance with all this international trade, moving things by the megaton all over the earth, many of those things being made of iron.
Plus all the iron and nickel ore being extracted from the earth to manufacture things must have some effect on the magnetic field.
We are messing with the Global Magnetic Field! We must stop all this trade and manufacturing NOW!!!!!!.......................
We should impose a mgnnetism tax on Africa and use it to offset the damage their selfish hegemony has wrought.
But what about Guam?
Why doesn’t anyone care about Guam?
It could flip, too!
Excellent. Yet another reason all of us to fly in to a blind panic and run around in circles in our living rooms yelling “wububba, wububba, wububba” until we collide with a wall or door frame and knock ourselves unconscious...
Another 5/5/2000 prediction......?
So if you flush the quarterback in the Northern hemisphere, will he go down clockwise, or counterclockwise?
Magnetic north was headed south fast, but, it is now headed west to Russia. Damned Russians.
So, after the shift, will Guam tip in the opposite direction than it would right now?
O nie!
