All results in this book are new and published for the first time. Based on the New Chronology and ancient sources, the authors show that the biography of the Prophet Mohammed consists of several layers. In particular, these are stories about Emperor Andronicus-Christ from the 12th century, as well as tales about Moses and Joshua from the 15th–16th centuries. The basis of the biography of Mohammed is probably information about the famous Sultan Mohammed II the Conqueror. It turned out that the famous Arab conquest was the Ottoman u003d Ataman conquest of the promised land in the 15th–16th centuries. It is shown that the fall of a large iron meteorite in Yaroslavl in 1421 was reflected in the Bible, Islam, Christianity, as well as in the “ancient paganism” of Ancient Rome and Ancient Greece. The reconstruction proposed by the authors is still conjectural, but the authors are responsible for the accuracy of the dating they calculated. The book is intended for a wide range of readers.
