More than four centuries ago, Nostradamus, a French physician and seer, predicted many events which later shook the world. The great fire of London, the rise of Hitler to power, the bombing of Hiroshima and Nagasaki, the assassination of President John Kennedy and the 9/11 terrorist attacks are some of the events he prophesied. The predictions do not follow chronological coherence and were written combining French, Greek, Latin and occitan. It is believed that it contains anagrams, mythological and astrological references, in a subjective language that makes comprehension difficult.
