Charles A. Ward is perhaps the best known of the academics who have endeavoured to explain the relevance of Nostradamus' prophecies.

Charles Ward was a believer and once you've read his book you will be too. He is also a consummate stylist; his convoluted Victorian prose will leave many readers rubbing their eyes.
