NEW SERIES airs Wednesdays at 9/8c on HISTORY. Was Leonardo Da Vinci, one of history's great philosophers, artists and engineers, a secret prophet? And did he envision world destruction of such biblical proportions that it haunted him until the end of his days? Clues hidden in Da Vinci's paintings, his re-discovered prophetic "riddles" and the events of his life now suggest that he, too, was influenced by the Nostradamus Effect.
