Nostradamus was a 16th century French astrologer and physician who published collections of prophecies that have since become famous. He correctly predicted several major world events including World War I, World War II, the rise and fall of Napoleon, and the death of Princess Diana. While some of his quatrains came true, others are more open to interpretation. He believed three major antichrists would bring destruction to the world, two of which have been identified as Napoleon and Hitler, with the third still to be revealed.
