Ancient Maps and Their Incredible Discrepancies with Modern Maps: A Journey into the Mysteries of Antarctica

Ancient Maps and Their Incredible Discrepancies with Modern Maps: A Journey into the Mysteries of Antarctica



We all know that there are levels of knowledge where the more you dig, the more you discover what was hidden beneath the surface, much like the tip of an iceberg. Most of the iceberg lies below the water's surface. Similarly, in the film "The Matrix," the question is posed: how deep does the rabbit hole go? Today's topic is ancient maps and their incredible discrepancies compared to modern maps. 



**The Mysteries of Antarctica**


Antarctica is a land of beautiful landscapes, natural ice walls, icebergs, possibly pyramids, and many other mysteries. The comparisons to the Ice Wall in the series "Game of Thrones," which separates the known world from the unknown, are striking. Today, we delve into what ancient maps say about Antarctica and the Arctic.


**Like and Subscribe**


If you enjoy this topic, be sure to like the video, subscribe to the channel, and join me as I reveal how deep the rabbit hole goes. 


**The Mercator Map**


Many have seen this map created by Gerardus Mercator, a cartographer depicted with a compass in hand. The Mercator projection, a famous map projection, is named after him. This map is well-known for its unusual depiction of the North Pole. In the Mercator map, America is shown in pink, Asia in yellow, with Iceland and Greenland prominently marked.


**The Enigmatic Four Lands**


At the center of the map, we see four lands surrounding a central mountain. Comparing Mercator's North Pole to the modern official North Pole, we notice that the lands Mercator depicted have disappeared. Did Mercator add these features for aesthetic reasons, or was there something more? 


**The Southern Hemisphere and the Great Discrepancy**


Looking at the Mercator atlas of 1595, we see "Terra Australis," meaning the land of the south in Latin. This map shows a certain harmony with current maps, except for a bulge west of South America. The significant discrepancy, however, is the size. The area of South America is 17,840,000 km², while Antarctica is 14,200,000 km². Yet, in Mercator's map, Antarctica appears almost twice as large as South America.


**Comparing Sizes**


Let’s test this. Placing South America on Mercator's Antarctica, we find it takes nearly two South Americas to cover it. This suggests that Mercator's Antarctica is approximately six times larger than the modern-day measurement.


**The History of Antarctic Maps**


Official history and science offer explanations for these discrepancies. Mercator’s map, while intriguing, is not alone. Abraham Ortelius, another cartographer, depicted Antarctica similarly in his 1570 atlas. Ortelius' map shows a massive, verdant Antarctica, challenging our modern perceptions.


**Orthodoxy and Speculation**


Other cartographers like Petrus Plancius and Jodocus Hondius also depicted Antarctica similarly. The official narrative suggests that these depictions were speculative, based on limited exploration. As navigators discovered more, the space for the hypothetical "Terra Australis" shrank, leading to its eventual disappearance from maps by the 18th century.


**The Enigma of Piri Reis**


Another fascinating map is the Piri Reis map of 1513. It shows parts of South America, Africa, and possibly Antarctica, depicted without ice and with detailed coastlines. The map's accuracy, based on older charts, raises questions about the historical climate and geography of Antarctica.


**Modern Understanding and Ancient Insights**


The differences between ancient and modern maps of Antarctica suggest significant changes in our understanding of the continent. Were these ancient maps based on observations or speculation? Is it possible that Antarctica was once ice-free, or has its representation been altered over time?


**Conclusion**


The rabbit hole goes deep when exploring ancient maps and their incredible discrepancies with modern ones. These maps offer a glimpse into a world that might have been very different from what we know today. Whether due to changing climates, forgotten knowledge, or artistic interpretation, these maps challenge our perceptions and invite us to keep digging.


**Engage and Explore**


What do you think about these ancient maps? Were they based on observations or speculation? Leave your thoughts in the comments and join the discussion. If you're curious to see where this journey takes us, remember to like and subscribe for more explorations into the mysteries of the past.



Ancient maps hold fascinating mysteries that challenge our understanding of history and geography. The stories they tell, whether based on observation or imagination, continue to captivate and intrigue us.

The first war criminal: Peter von Hagenbach

In the 20th century, we had many individuals convicted of war crimes, with some sentenced to death. However, the first recorded trial of this kind was in Europe during the Middle Ages, over 500 years ago, a topic covered in the Nerdologia podcast. Welcome to a new episode of "História Nerdologia." My name is Felipe Figir.


As a history columnist, podcaster, YouTuber, professor, and someone familiar with law, or if you watched Nerdologia's episode on the trial of Peter Von Hagenbach in August 2023, we discussed the history and establishment of the International Criminal Court, currently prominent in the news. It is the first permanent international tribunal for judging individuals for genocide, crimes against humanity, war crimes, and the crime of aggression.


In that video, we commented on how history, unfortunately marked by violence, has many well-documented events since antiquity characterized as massacres or similar terms, especially during wartime. This violence sparked moral and ethical debates condemning episodes of excessive or unnecessary violence and advocating for what should be appropriate or ethical conduct for a warrior.


From the Code of Hammurabi onward, topics like the treatment of prisoners, pillaging of cities, and the recognition of vulnerable groups such as the elderly and children have been present across various cultures throughout history. Although not codified as war crimes as they are today, such acts were prevalent in medieval Europe, integral to its portrayal in films, series, and games—perhaps even excessively compared to reality.


On May 9, 1469, in the region of Padre Calé, the Treaty of San Omer was signed. Duke Sigismund of Habsburg leased some of his lands in southern Alsace to Duke Charles of Burgundy for 50,000 florins, a currency containing gold. Sigismund aimed to form a defensive alliance with Charles to better defend his lands against the French and Swiss, also using the money to acquire land in the Alpine region of Tyrol.


The Duchy of Burgundy enjoyed significant autonomy and rivalled its more powerful neighbors, situated between the Kingdom of France and Germanic lands, sometimes aligning with one and sometimes with another. At various times, it even served as a vassal of France. Charles of Burgundy appointed a knight named Peter Von Hagenbach as his administrator of the leased lands, including a smaller territory in Alsace.


He organized a small army and set out to control the new territories, which turned into a disaster. Initially, local German-speaking people did not welcome a new ruler who spoke French and was a vassal of the Duke of Burgundy. Peter Von Hagenbach proved to be a cruel and violent administrator, increasing taxes, imposing recruitment of farmers, and his soldiers were abusive and violent towards villagers. He ordered roadblocks, tolls, and bribes from Swiss merchants passing through, even though they were not under his authority. Reports of abusive arrests surfaced.


When representatives from the village of Tan requested an audience to complain, they were executed without trial. According to accounts cited by the French historian Baron de Barante, Peter Von Hagenbach was prone to using sexual violence against women as a weapon, authorizing his soldiers to commit such crimes freely and committing such acts himself, including against a nun.


At the same time, Peter Von Hagenbach was trusted by the Duke of Burgundy, serving as an interpreter in official talks between the Duke and Emperor Frederick III of the Holy Roman Empire, discussing a potential marriage between their children. Peter Von Hagenbach's actions against Swiss merchants prompted closer ties between the Swiss Confederation and the Duke of Austria, who leased the lands, arguing that the tax increase violated the lease agreement.


Sigismund of Habsburg sought the return of his lands, but Charles of Burgundy refused. Simultaneously, some cities in the region rebelled against Peter Von Hagenbach. An anti-Burgundy league formed, including the Swiss, the Duke of Austria, and rebellious cities in Alsace, part of a larger war lasting several years—Burgundian Wars.


The league defeated Peter Von Hagenbach's soldiers, who took refuge in the city of Brisach. The city did not want him there, so he repeated his customary actions: massacring part of the inhabitants. His behavior was so tyrannical that his own soldiers mutinied and handed him over to the enemies.


The Duke of Austria decided to convene a jury of 28 representatives from the major cities forming the league to judge the knight. The trial began at 8 a.m. on May 9, 1474, in Saas. Peter Von Hagenbach's defense argued that the court had no authority, that the accusations of sexual violence were actually consensual encounters, and that his actions were merely obeying the orders of his lord, the Duke of Burgundy. According to the records, one of his representatives said that he recognized no judge or master other than the Duke of Burgundy, from whom he received his commission and orders. He had no right to question the orders he was tasked to execute, and it was his duty to obey.


By 4 p.m. that day, the jury found Peter Von Hagenbach guilty of murder, sexual violence, perjury, and pillaging. He symbolically lost his titles and was sentenced to death. Representatives from seven cities vied for the chance to be the executioner. The criminal asked for forgiveness for his crimes and for other even worse things, and was beheaded with an axe, according to Father Erhard Von Oppenweiler. 6,000 people were reportedly present.


Later, Peter Von Hagenbach's history of cruelty took on legendary proportions, with his mummified head displayed, and stories of his ghost haunting a forest. His widow ordered the construction of a chapel in his honor, demolished in the 16th century to build a fortress. In the 20th century, a play was written about him.


With the consolidation of scientific historical methodology, historians began to address other issues, considering that some of Peter Von Hagenbach's crimes may have been exaggerated to ensure his guilt not only for the crimes he committed but also to serve as a scapegoat to exonerate the Duke of Burgundy.


His trial was resurrected as a precedent during preparations for the trials of Nazi criminals in Nuremberg after World War II. Peter Von Hagenbach's defense that he was merely following orders was not accepted in his time, and in 1946, it became the fourth principle of Nuremberg: that a person cannot justify a crime by claiming they were just following orders; this effectively creates two guilty parties and does not absolve those involved.


Today, the Nuremberg principles are a crucial part of international law against war crimes and crimes against humanity. Peter Von Hagenbach is considered the first war criminal in the modern sense of the term. Remember, this video is a condensed version; unfortunately, many fascinating details had to be omitted. Sources and further suggestions are available in the description and comments of Nerdologia.

The Trial of Peter von Hagenbach: A Landmark in War Crimes Justice

**The Trial of Peter von Hagenbach: A Landmark in War Crimes Justice**


In the annals of history, the 15th century marked a significant turning point with the trial of Peter von Hagenbach, a momentous event often overshadowed by more recent legal precedents. Situated amid the tumultuous backdrop of medieval Europe, this trial stands as a seminal episode in the evolution of international law concerning war crimes.


Peter von Hagenbach, a knight appointed by Duke Charles of Burgundy, governed a region in Alsace with an iron fist during the mid-1400s. His administration was marked by brutal taxation, arbitrary imprisonment, and heinous acts of violence, including reported sexual assaults against women. These atrocities sparked local outrage and ultimately led to his trial in May 1474.


Convened in the town of Breisach, the trial was extraordinary for its time. It represented a stark departure from the prevailing norms where such acts of cruelty by feudal lords often went unpunished or were dealt with leniently. The proceedings, conducted by a jury composed of representatives from several cities in the region, charged Hagenbach with murder, rape, perjury, and pillaging.


The defense argued that Hagenbach was merely executing orders from his superior, Duke Charles, and therefore should not be held individually accountable—a defense eerily reminiscent of subsequent claims made during more modern war crime tribunals. However, the jury’s verdict was unequivocal: Hagenbach was found guilty on all counts and sentenced to death by decapitation.


The execution of Peter von Hagenbach resonated far beyond the borders of Alsace. It set a precedent that transcended the era, influencing legal doctrines centuries later, particularly during the Nuremberg Trials after World War II. The principle that individuals cannot evade responsibility for their actions by citing superior orders—a principle underscored in the Nuremberg Principles—was foreshadowed in Hagenbach’s trial.


In contemporary context, Hagenbach serves as a poignant reminder of the enduring struggle to uphold justice in times of conflict. His trial highlighted the evolving moral and ethical standards surrounding warfare, challenging the impunity often enjoyed by those in positions of power.


Today, the legacy of Peter von Hagenbach endures not only as a historical curiosity but as a foundational moment in the development of international humanitarian law. His trial represents a pivotal step towards holding individuals accountable for egregious acts committed during war—a principle that continues to shape legal frameworks aimed at preventing atrocities and protecting human rights worldwide.


As we reflect on this watershed moment in history, we are reminded that justice, though often belated and imperfect, remains a beacon of hope in the face of unchecked brutality.
