From his predictions about life and death in the Middle French court of Catherine de' Medici to his uncannily suggestive preconceptions of World War II, Michel de Nostradamus has aroused continual fascination-and commercialization-in the West. Today, many search his elliptical "centuries"-or collected verses-for new truths about 9/11 and End Times, while supermarket tabloids routinely falsify and exploit his pronouncements. What is the difference between prophecy and prediction, and how has it led to a misuse of the ideas of Nostradamus, as well as those of other post-biblical prognosticators? What is the nature of the oracular tradition in the West-stretching back to the oracle at Delphi-and how can Nostradamus be understood from this perspective? In The Essential Nostradamus, the highly regarded spiritual thinker and writer Richard Smoley provides a true sourcebook in the life and messages of one of history's most peculiar figures.
