Secrets & Mysteries of the Sephardim : Lulu.com : 9781329051904 : 1329051904 : 23 Feb 2023 : The book "Secrets & 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. Manu
