How might one interpretation involve a asteroid impact?
A possibility (originally proposed in Charles Berlitz in ‘Doomsday 1999 AD’ (1981) and taken up by Stefan Paulus in ‘Nostradamus 2000 – who will survive’ (1996)) is that the King of Terror refers to a comet/ asteroid which will hit the earth causing devastation and a shift of the east/west power balance, enabling the rise of the 3rd Antichrist. Heavenly bodies have been treated in an anthropomorphic fashion throughout history, hence the reference to a King. Most of the rest of this document will explore this possibility.
