Christopher Columbus: Master Double Agent and Portugal’s 007

(Read the article on one page)

Henry IV of Spain – known as "The Impotent" for his weakness, both on the throne and (allegedly) in the marriage chamber – died in 1474. A long and inconclusive war of succession ensued, pitting supporters of Henry's 13-year-old heir, Juana de Trastámara, against a faction led by Princess Isabel of Castile and her husband, Ferdinand of Aragon. Portugal, Spain's much smaller antagonist for centuries already, sided with the loyalists.

The civil war ended in 1480, with the Treaty of Alcáçovas/Toledo, whereby Portugal withdrew support for Juana; in exchange, Isabel and Fernando promised not to encroach on South Atlantic trade routes that Portugal had long been exploring and wished to monopolize.

Treaty Not Worth Much

Spain immediately began to violate the Treaty of Alcáçovas. Portugal's gold trade with Ghana was a powerful enticement, but the Spanish were also lured by the priceless knowledge that Portugal had painstakingly gathered about the currents, territories, winds and heavenly bodies relative to the Atlantic regions. The Portuguese were far advanced in the sciences of geography and navigation pertaining to the Atlantic Ocean, both south and west of Portugal itself.

Meanwhile, John II ascended to the throne of Portugal in 1481, reversing the policies of his father, another weak, late-Medieval ruler who'd surrendered excessive estates and privileges to the nobility.

Large swaths of the noble class rebelled, but John II was an astute diplomat, with powerful alliances among the military and religious orders across Europe, along with an extensive network of spies. He sprang a trap on his adversaries, capturing and executing the ring leader.

Queen Isabel supported the traitors in Portugal, having obtained their promise to annul the Treaty of Alcáçovas. When the conspiracy was exposed, numerous traitors among the Portuguese nobility fled to Spain, where they found asylum, along with a base from which to continue their hostilities against John II. Prominent among the defectors were two nephews of the highly-born wife of Christopher Columbus – who would himself sacrifice the next twenty years of his life to join this exodus, faking desertion to his sovereign's most bitter foe. The internecine strife was so keen that after another occasion when his agents had tipped him off, which resulted in John II personally executing the Duke of Viseu, he threatened to charge his own wife with treason for weeping over her brother.

The Mother of All Secrets

It's now been amply proven that evidence of hostility between Columbus and John II was fabricated. Columbus was, in fact, a member of John II's inner circle, in addition to being one of the most seasoned of all Portuguese mariners. After his false defection to Spain, Columbus attended three secret meetings with John II, the second of these, in 1488, being prompted by the mother of all maritime secrets: Dias having rounded the Cape of Good Hope, thereby establishing the shortest route to India by sea.

Christopher Columbus was arrested at Santo Domingo in 1500 by Francisco de Bobadilla and returned to Spain, along with his two brothers, in chains.

Now, the Holy Grail of all commercial bonanzas was a sea route to the riches of India – sought because Christendom was at war with Islam, and Muslim armies blocked the much shorter land routes across the Middle East. What the most knowledgeable Portuguese pilots knew was top secret, state of the art, a scientific prize for international espionage.

The Portuguese discovered numerous territories and routes during the 15th and 16th centuries. Cantino planisphere, made by an anonymous cartographer in 1502.

The Portuguese had been the first Europeans to launch expeditions in search of the Equator, which they reached around 1470, discovering while they were at it, the islands of São Tomé and Príncipe. By 1485, expert Portuguese technicians had invented charts and tables – based on the height of the sun at the Equator – which allowed navigators to determine their location in the daytime. While King John II was keeping Columbus up to date with all of the cutting-edge developments in maritime science, he was at the same time spreading so much disinformation elsewhere—among friends and foes alike— that we are still unraveling it.


Excellent article!

Is it only a coincidence. then, that the infamous Spanish Inquisition began the very day Columbus set sail in 1492?

 If you consider that Colon was trying to have his voyage sponsored since 1485, then Yes, it was conincidence. Besides, the Inquisition started after 1492. What happened in 1492 was the expulsion of the Jews. Because Isabel and Fernando had, in December 1491 freed Granada, -the last lands of Iberia occupied by the Muslims - and wanted a wholy Christian kingdom, they ordered the Jews, whose ancestors had been living there peacefully for centuries, to leave Spain.

Once upon a time, long before wars, natural disasters and erosion took hold of the ancient Greek statues, these ivory gems vibrated with color. Ancient Greek sculptors valued animated and pulsating depictions as much as they valued perfection and realism, and it has finally become fact that these artists utilized color in their creations.

Myths & Legends

 “Cadmus Slays the Dragon” by Hendrik Goltzius. The Greek myth of Cadmus fighting the serpent may be an allegory for the discovery of the Amazon River. In various accounts, the snake is instead referred to as a dragon or serpent.
The ancient Greek myth of Cadmus battling a snake could be an allegory for the discovery of the Amazon River, said Dr. Enrico Mattievich, a retired professor of physics from the Federal University of Rio de Janeiro (UFRJ) in Brazil. Mattievich wrote a book titled “Journey to the Mythological Inferno” in 2011, exploring connections between Greek myths and South American geographical and historical sites.

In 1526, the Spanish conquistador Francisco de Montejo arrived on the Yucatan Peninsula of Mexico and found most of the great Maya cities deeply eroded and unoccupied. Many generations removed from the master builders, engineers, and scientists who conceived and built the cities, the remaining Maya they encountered had degenerated into waring groups who practiced blood rituals and human sacrifice.

Our Mission

At Ancient Origins, we believe that one of the most important fields of knowledge we can pursue as human beings is our beginnings. And while some people may seem content with the story as it stands, our view is that there exists countless mysteries, scientific anomalies and surprising artifacts that have yet to be discovered and explained.

The goal of Ancient Origins is to highlight recent archaeological discoveries, peer-reviewed academic research and evidence, as well as offering alternative viewpoints and explanations of science, archaeology, mythology, religion and history around the globe.

We’re the only Pop Archaeology site combining scientific research with out-of-the-box perspectives.

By bringing together top experts and authors, this archaeology website explores lost civilizations, examines sacred writings, tours ancient places, investigates ancient discoveries and questions mysterious happenings. Our open community is dedicated to digging into the origins of our species on planet earth, and question wherever the discoveries might take us. We seek to retell the story of our beginnings.
