Did Nostradamus Predict 9/11?

NO.  The quatrain which is often quoted is VI. 97, which references the sky burning at latitude 45 degrees, fire burning in the "New City," and something about "Normans."  45 degrees latitude is not New York City.  It's Maine. Some have tried to argue that "45 degrees" meanss 40.5 degrees latitude.  Unfortunately, however, the decimal system was not even invented in France at that time.  "Cinq et quarante degres" would not be the way a Frenchman would describe 45 degrees.  Prof. Lemesurier postulates that Villeneuve-sur-Lot, which sits at 45 degrees and whose name means "new city," is the city referenced in this quatrain.  However, if we were to use 40.5 degrees, then the "new city" could just as easily refer to Naples, which in Greek means "new city," which also sits at 40.5 degrees latitude, and which is near Mt. Vesuvius (fire from the sky).  But if this prophecy is supposed to refer to 9/11, what, pray tell, did the Normans have to do with 9/11?
