"Les Prophéties" is a collection of verses written by the French seer Nostradamus in the 16th century. The work consists of 942 quatrains, which are four-line poems that predict future events. Nostradamus's writings cover a wide range of topics, including wars, natural disasters, and political upheavals. The quatrains are often cryptic and open to interpretation, leading to various analyses over the centuries. Many people believe that some of his predictions have come true, while skeptics argue that the verses are too vague. Despite the controversy, "Les Prophéties" remains a significant work in the study of prophecy and mysticism.
