Nostradamus 10:72 says

X 72

L'an mil neuf cens nonante neuf sept mois;
Du ciel viendra vn grand Roy d'effrayeur;
Resusciter le grand Roy d'Angolmois;
Auant apres Mars regner par bon heur.

"Year 1999, seventh month;
There will come from the sky a great king of terror;
to resuscitate the great King of the Angolmois (anagram for "Mongolians")
Before and after, Mars will reign happily"

Well now there's a couple of "Terrifying" things in the sky on July 29, 1999 (O.S.).

There's a third "sign in the sky I would like to mention: Two amateur astronomers named Hale and Bopp simultaneously discovered a comet after midnight Sunday July 23, 1995...

...that was 107 times 77 days before tonight, and was in the 1999th year since the coming of Christ, January 1995 being 1998 years since the Annunciation and Conception of Christ)

Another type of "King of Terror" occurred when a nationwide blackout--the worst in 50 years--struck Taiwan late July 29, 1999, causing fears that an invasion by Communist China had begun.
