The obscuration is claimed to have been done to avoid his being tried as a magician. Of course a skeptic might say it was done so the quatrains could be interpreted to fit numerous situations.
An example of one of his more famous quatrains is from Century #2 Quatrain #24. The French and English versions are as follows:
Bestes farouches de faim fleuues tranner; Plus part du champ encontre Hister sera,En cage de fer le grand fera treisner, Quand rien enfant de Germain obseruera.
Beasts ferocious from hunger will swim across rivers: The greater part of the region will be against the Hister, The great one will cause it to be dragged in an iron cage, When the German child will observe nothing.
So does Hister actually refer to Hitler? An instance of Nostradamus changing letters around? Is this a reference to Germany during WWII? (Activemind.com)
