Michel de Nostredame loved from 1503 to 1566. He was most well known during his life as an apothecary. He was also an astrologer and known as what was known as a seer someone who can see things that are going to happen in the future. During his life he worked hard to document his large range of prophecies that have become extremely popular in recent times.
In reality the vast majority of his writings were extremely obtuse. When anything happens in recent times that seems to have significant historical context there is a means to connect it to something that had been said by Nostradamus. That does not mean that his prophecies have absolutely no merit, but it is something to be considered when trying to connect them to things that happen in our world.
During his life he was most famous for prophecies that he printed inside of his almanacs. He became so popular among elites that he was eventually summoned to Paris to meet with Catherine de Médicis who was the wife of King Henry the II, of France. At the time he was concerned that he would be persecuted, but he was so favored that he was appointed as Counselor and Physician-in-Ordinary for her son.
He did also do prophecies for individuals. He had a major flaw, however, in that he refused to take the time to chart out their place and time of birth and translate is appropriately as was the custom of astrologers. Many of his clients did not find this concerning, but others accused him of being a fraud.
In modern times it is believed that he prophesied a number of wars, the robbing of his own grave, the invention of aircraft and more. With the election of various leaders it has been asserted that they were the coming of the anti-christ that Nostradamus spoke of in his quatrains. This is directly related as well to the threat of a war that will be bigger than all other wars ever known. Leaders around the world have been believed to fit the description.
Nostradamus is either is believed to predict the future, or simply a fraud that had an irrational beliefs about his abilities depending on who you ask. In either case, his story has stood the test of time. There is no doubt that the story of Nostradamus and his quatrains will continue to lead to speculation regarding their accuracy.
