Secrets & Mysteries of the Sephardim

The book "Secrets and Mysteries of the Sephardim"  focuses on events on the Iberian Peninsula  in the 15th century.
    It is based on historical facts about the lives of the Portuguese and Spanish monarchs.  These facts are partially or fully opposite to the legends created by the monarchs and influential political figures of the Holy Roman Empire  of that time.
    It is also based on the archival data of papal bulls  found in the Vatican Apostolic library and many other archival sources.
    And, of course, it is based on the genetic research of Christopher Columbus' brother and son's genes. This research and Columbus's writing style questioned Columbus's Italian origins and revealed his Portuguese-Sephardic origin. It also proves that Columbus' birthplace was not Italy or Spain but Portugal. Readers can find a detailed description of the research in the book, "Christopher Columbus was Portuguese!" by Dr. Manuel Luciano da Silva.
    Another mystery is where the name Columbus originated. There were many cases in history where people took the surnames of those who influenced their lives significantly.
    In the opinion of this book's author, Christopher Columbus might have taken the name of a person whose identity he could not reveal because of sensitive circumstances. But who was this person? And what heroic deed did this person perform that affected him so profoundly?
    Along with the great Sephardim, such as Columbus and other prominent Sephardim who glorified the Sephardim throughout the world with their deeds, the first book includes characters from the time of Columbus who dishonored their Sephardic origin with their actions. These people are inhumane and include, among others, Thomas Torquemada.
