Nostradamia investigates the validity of the prophecies of Nostradamus contained in his poems titled The Centuries. The actual meaning of the Centuries can only be found through the knowledge of the Middle Ages French language, Provencal, which is close to the Catalan language, the history of Grecve, Rome and Rebirth era, the Revelations and Daniel Biblical prophecies and the political environment of the 16th Century in France.
