Another nutty conspiracy theory!! That’s what I first supposed.
I now believe Christopher Columbus is guilty of a huge fraud.

This new book, COLUMBUS versus COLÓN, is the English edition of a doctoral dissertation proving once and for all that the 500-year history was false. Uncovering the truth about Christopher Columbus, the putative discoverer of the Americas, is more than just an esoteric quest for knowledge of the 15th century. Dr. Rosa’s research reveals how the explorer was born a Portuguese nobleman in 1455, not an Italian weaver born in 1451.  

Forged documents led historians astray for centuries. Christopher Columbus’ history was a devious labyrinth falsified by many different actors working in different centuries and for different reasons. 


A Falsified Story

Documents about some Cristoforo Colombo weaver from Genoa, include many forgeries, as Ulloa, Altolaguirre, Strahan and others declared. The Contemporary Review (1937) stated that “the forgery of documents referring to Columbus has not stopped, being more intensified after his death.” Consuelo Varela described forged documents stating that “the great celebration of the 400th Anniversary brought out forgers that were better experts.” Guadalupe Chocano mentions the doubts and contradictions inherent in the Genoese documents. Ezquerra Abadía observed that many Genoese documents were not authentic, saying that “with a certain abundance have appeared in the current century.” 

The Raccolta Colombiana was a government propaganda incentive that served the purpose of grafting a Genoese weaver Colombo into the noble navigator’s story, even if by fraud. It was not a search for the truth. 

Armando Cortesão wrote that many Genoese documents “were later discovered to be forgeries” and was astonished that such a keystone document as the Assereto had never been found in the Genoese archives until the Genoese needed to prove 1451 as the year of their Colombo’s birth. The Assereto Document is the most egregious fraud committed against academics and the historical truth in the last century. 

At any time, the Italian lobby could have opted for seeking truth and let the world know about their lack of documents. Instead, they chose to bluff the world with misleading documents and their manipulations succeeded in deceiving thousands of academics for over 100 years. By deceiving countless biographers and investigators, this fraud was a crime against the Humanities. We are deceived no more! 

What COLOMBO versus COLÓN presents are the solid facts on which to anchor a new biography and a new and more accurate story. 


33 Years of Research  

Extraordinary claims require extraordinary evidence and Dr. Manuel Rosa did an unbelievable job as an investigative detective matching up documents from different countries to show how the world had accepted a history as being written in stone when it was actually written on shifting sands. The amount of new information in Columbus versus Colón is amazing for anyone who likes true conspiracy and mystery detective tales, except this one turns out to be a true story. 

Columbus versus Colón deals meticulously over Columbus’ name and country of origin. I’ll say the book is painstaking in trying to determine his birth and lineage. The author methodically checks off the lies, the misinformation, the forgeries, and focuses on the aspects of Don Cristóbal Colón’s life the historians had ignored or tried to explain away with ridiculous assertions. This doctoral dissertation is a  fantastic book, well researched, complete with details and sources. A stunning array of artifacts and data connecting the dots to a medieval conspiracy, so massive, so bold, so risky, and so well executed, that it has continued to fool the world for 500 years.    


COLUMBUS in the Crosswind   (Lisbon, 2024)

COLUMBUS in the Crosswind is an abridgment of COLUMBUS the Untold Story written at the request of the Admiral of the Portuguese Navy Fleet, Henrique Gouveia e Melo. He plans to gift copies of the book to his counterparts during foreign travel.

I am honored to have  Admiral Gouveia e Melo's support in the promoting of the historical truth.  

The book release was held at the Navy Museum in Lisbon on June 3, 2024 and is only available for sale at the Museum store in Lisbon.

I am currently seeking a US publisher for this shorter version which is perfect for readers who are not interested in all the documents and details of this 500-year-old labyrinth.

Columbus history is changing. Christopher Columbus is no longer Italian. In fact his name was never even Columbus. Eventually all history books will be changed to present the corrected story, until then, your only source for the explanation of the truth and the explanation of the lie is COLUMBUS the Untold Story which can be purchased here: Columbus-Book.com and COLUMBUS in the crosswinds can be purchased at the at Museum Book Store

COLUMBUS IN THE CROSSWINDS

A work by one of the most respected historians today.

ONE OF THE BIGGEST SECRETS OF THE PORTUGUESE MARITIME EXPANSION


In 1492, Captain Cristóvão Colón led a three-ship expedition to the Caribbean, which generated great interest and speculation about new lands in the west.

For centuries, Colón's journey was considered the first made by Europeans to the New World, but this is not true. Vikings had previously inhabited parts of Greenland and Canada, and the Portuguese also visited Canada before 1424.

The evience presented in this book reveals that Portuguese navigators had already arrived in Brazil before 1494, during the reign of D. João II. This discovery, surrounded by secrecy, would have been the main motivation for signing the Treaty of Tordesillas. ( More…

The truth is that the book is AWESOME!!! The wealth of information, the clarity and beauty of the scripts and the pace of an authentic suspense thriller make the book impossible to put down. The book leads to surprising reflections (which leave the reader awestruck) as well as obvious reflections which make the reader wonder: 'How come I didn't think of this before?'

Manuel Rosa (center) awarded PhD in Insular and Atlantic History (XV-XX Centuries) – Azores University “unanimously and with distinction” with a dissertation titled CRISTOFORO COLOMBO versus CRISTÓBAL COLÓN: CristoforoColombo, weaver from Genoa, was not Don Cristóbal Colón, the navigator from Ibéria.

- What Manuel Rosa has accomplished by writing "Columbus-The Untold Story" is stunning. Through his extensive research, familiarity with traditions and customs of the times, and his mastery of Portuguese, Italian, and Spanish, he has managed to piece together and expose a history, taught to us and our children, fraught with inaccuracies and outright lies about "The Great Discoverer," Christopher Columbus.

- Lot of detail… fascinating story impressive research.

- The truth is so much more exciting than fiction taught in school books. Columbus - The untold story has made me wonder... What other "history" has been twisted?

- I have read many books on Columbus, but Columbus - The untold story gives only rational reason why Columbus advised the Spanish Crown to sail West to reach the Indies! He was Portuguese and a Portuguese agent.

- Sometimes the work of scrupulous historians with a very inquisitive mind offers us a very decent and convincing account on the historical revisionism. Recently Manuel Rosa the American amateur historian with Portuguese roots provided a book entitled “Columbus - The untold story'', in which he presented convincing theory already partially supported even by investigations of DNA material… This is a example of a very decent and well-researched historical revisionism that is supported by the scrupulous and tedious analysis of available sources.

- Extraordinary claims require extraordinary evidence and Manuel Rosa did an unbelievable job as an investigative detective matching up documents from different countries to show how the world had accepted a history as being written in stone when it was actually written on shifting sands. The amount of new information in Columbus the Untold Story is amazing and it has convinced me that Columbus was indeed a Portuguese secret double agent and the 1492 voyage was all a big ruse against Spain. This book will make a great cloak and dagger film. I highly recommend its reading to anyone who likes history, true conspiracy and mystery detective novels, except this one turns out to be a true story.

- Fantastic book. The author methodically checks off the lies, the misinformation, the forgeries, and focuses on the aspects of Colón's life the historians have ignored or tried to explain away with ridiculous assertions…. I cannot wait for more information to come to light!

- Columbus the Untold Story deals meticulously over Columbus’s name and country of origin. I’ll say the book is painstaking in trying to determine Cristoforo’s birth and lineage through an interesting theory on why Columbus’s stuck to his discovery of ‘India.’

- If you want a book that is well researched, complete with details and sources, then this is the tome for you… a stunning array of artifacts and data, complete with DNA test results; one that resulted in the deceitfulness of power, of politics, false identities and false discoveries… connects the dots to a medieval conspiracy, so massive, so bold, so risky, and so well executed, that it has continued to fool the world for 500 years. Columbus the Untold Story , without a doubt, is one of the best to captivate me in a very long time.
