#446 – Ed Barnhart: Maya, Aztec, Inca, and Lost Civilizations of South America

1-Page Summary

Theories about lost or undiscovered ancient civilizations in the Americas

Archaeologist Ed Barnhart suggests evidence points to an advanced civilization thriving in the Amazon rainforest, contrary to common assumptions about the region.

Barnhart cites Terra Preta soil and large geometric earthworks as signs of extensive farming and urban settlement. Areas like the Xingu in Brazil display mounds and causeways indicative of dense populations and advanced city planning.

While Barnhart is open to undiscovered civilizations, he disagrees with theorist Graham Hancock's hypothesis of a single "mother civilization" that spawned all later societies.

Barnhart argues the lack of physical evidence makes Hancock's claims implausible. He believes sophisticated cultures developed independently, with cultural similarities stemming from common ancestry rather than external influence.

The origins, development, and sociopolitical structures of major Mesoamerican and South American civilizations

The Maya possessed a highly advanced civilization with complex religious beliefs centered on a "fanged deity" and a sophisticated writing and calendar system.

Their sociopolitical structure shifted from hereditary dynastic rule to decentralized council systems over time.

The Inca built a vast empire in the Andes sustained by the "mita" rotating labor system and a knotted string record-keeping method called "khipu".

The Inca strategically assimilated conquered populations, transporting ancestral mummies to Cusco to symbolize dominion while honoring their heritage.

The impact of European contact and colonization on indigenous populations

Following European arrival, up to 90% of indigenous populations perished due to epidemics, resulting in an immense loss of knowledge and cultural erosion.

Barnhart recounts how European explorers like Hernando de Soto brought disease, violence, and oppression, decimating societies like the Maya and Aztec.

The "Mississippian Shatter Zone" describes how previously thriving indigenous societies across North America were dispersed and displaced by European expansion.

Barnhart advocates teaching "Before the Americas" in schools to fully recognize pre-colonization civilizations' history.

Counterarguments

  • While Terra Preta and geometric earthworks suggest advanced civilization, some scholars argue that the extent of urbanization and complexity in the Amazon is still not fully understood and requires more evidence.
  • The interpretation of the Xingu's mounds and causeways might be contested by some archaeologists who may argue for different functions or scales of settlement.
  • Some researchers might support aspects of Hancock's theories, suggesting that there could be shared knowledge or contact among ancient civilizations, even if not a single "mother civilization."
  • The understanding of Maya sociopolitical structures is complex, and interpretations can vary; some scholars might argue that the shift from dynastic rule to decentralized systems was not uniform or did not occur in all regions.
  • The efficiency and reach of the Inca's mita system and the interpretation of khipu are subjects of ongoing research, with some scholars proposing alternative views on how these systems functioned.
  • The strategy of Inca assimilation and the role of ancestral mummies could be interpreted differently by scholars focusing on regional variations or resistance to Inca policies.
  • The figure of up to 90% population loss due to European contact is debated among historians and demographers, with some arguing for lower mortality rates or different timelines for population decline.
  • The impact of European explorers is a complex topic, and some historians might emphasize the diversity of indigenous responses, including adaptation and resistance, rather than only victimization.
  • The concept of the "Mississippian Shatter Zone" is one of several frameworks for understanding the impact of European expansion, and alternative models or interpretations may be proposed by other scholars.
  • The advocacy for teaching "Before the Americas" is a pedagogical choice that might be challenged by educators who prioritize different historical narratives or methods of instruction.

Actionables

  • You can deepen your understanding of pre-colonial civilizations by creating a themed book club that focuses on indigenous cultures and histories. Start by inviting friends or community members who share an interest in history.

#446 – Ed Barnhart: Maya, Aztec, Inca, and Lost Civilizations of South America

Theories about lost or undiscovered ancient civilizations in the Americas

The dialogue between experts reveals both the looming possibilities and the skeptical viewpoints regarding lost or undiscovered ancient civilizations in the Americas, specifically within the lush landscapes of the Amazon rainforest and beyond.

Ancient civilizations may have existed in the Amazon rainforest that have been swallowed up by the environment over centuries

Ed Barnhart, an archaeologist, discusses the untapped potential of the Amazon rainforest in revealing ancient civilizations. He suggests that while the Amazon might not be a commonly discussed hub of ancient civilization now, it could become a focal point in the future due to its earliest pottery and potential evidence of the region's distant significance.

Archaeologists have found evidence of large geometric earthworks, Terra Preta soil, and other signs of past human settlement in the Amazon basin, suggesting the possibility of an advanced civilization that has been obscured by the dense vegetation

Evidence of Terra Preta, or Black Earth, along with large geometric earthworks in the Amazon basin, points to significant farming and human activity that could suggest a vast civilization. More of these structures are being uncovered as forests are opened up, ranging from the bottom of Bolivia to Guyana. The Xingu area of Brazil, among others, displays evidence of civilizations with large mounds and extensive causeways that indicate dense populations and advanced city planning.

Despite the dense jungle environment, the dialogue suggests that exploring these areas could uncover civilizations like the difficult-to-explore Maya region. Barnhart emphasizes the importance of reasserting the presence of great civilizations in the Americas prior to European contact.

There are theories that a single lost advanced ancient civilization may have seeded the development of later Mesoamerican and South American cultures, but archaeological evidence does not conclusively support this

Ed Barnhart confronts Graham Hancock’s hypothesis of a lost "mother civilization" that influenced subsequent cultures. He points to the stone depictions in Chavin de Huantar, which suggest indigenous practices and religions possibly originating from an ancient Amazonian civilization. This deity and its iconography potentially diffused into Andean civilizations.

Theories about lost or undiscovered ancient civilizations in the Americas

Additional Materials

Counterarguments

  • The idea that ancient civilizations in the Amazon were "swallowed up" by the environment could be challenged by the argument that the evidence of such civilizations may have been misinterpreted, and what is seen as signs of large settlements could be natural formations or smaller-scale human impacts.
  • The interpretation of geometric earthworks and Terra Preta as signs of an advanced civilization could be countered by the view that these could represent the activities of less complex, semi-nomadic groups engaging in practices like slash-and-burn agriculture, which can also lead to soil enrichment.
  • The comparison of the Amazon to the Maya region might be criticized for potentially oversimplifying the unique cultural and environmental contexts of each area, which could lead to inaccurate conclusions if one region's history is used as a template for the other.
  • The emphasis on reasserting the presence of great civilizations in the Americas prior to European contact could be met with the argument that the term "great" is subjective and Eurocentric, and that all cultures have intrinsic value regardless of their material achievements or visibility in the archaeological record.
  • The lack of conclusive archaeological evidence for a single lost advanced ancient civilization could be countered by pointing out that absence of evidence is not evidence of absence, and that many archaeological discoveries are made long after initial hypotheses are formed.
  • The disagreement with Graham Hancock's hypothesis might be criticized for potentially being too dismissive of alternative historical interpretations that could be considered once more evidence is available or new analytical methods are developed.
  • The argument for independent development of sophisticated cultures could be challenged by the idea that cultural diffusion and interaction between different regions and peoples could have played a significant role in the development of complex s ...

#446 – Ed Barnhart: Maya, Aztec, Inca, and Lost Civilizations of South America

The origins, development, and sociopolitical structures of major Mesoamerican and South American civilizations

In this examination of ancient civilizations, the intricate development and sociopolitical structures of the Maya and Incan empires are explored, revealing their sophisticated cultures and belief systems.

The Maya civilization exhibited a highly advanced culture and belief system, including a sophisticated calendar and writing system

The Maya had a complex religious worldview centered around a "fanged deity" that recurred across their art and iconography over thousands of years

Ed Barnhart recognizes a "fanged deity" shared across several Andean civilizations, indicating a complex character with a broad role in Maya belief systems. This deity is represented with circular eyes, a fanged mouth, and snakes emanating from its head and belt, indicative of its involvement in both the more terrifying and ordinary aspects of Maya religion. Despite the deity’s fearsome representation, including being depicted with severed human heads, it’s also shown in a softer light, for instance, with a puppy, suggesting multifaceted significance in their religious worldview.

Maya society was originally organized around hereditary royal dynasties, but later shifted towards more decentralized, council-based systems of governance

Barnhart describes the Maya's original sociopolitical structure as kinship-based, with royal dynasties ruling for approximately 400 years, a period known as the "Age of Kings". This dynastic rule legitimized the divine authority of elites to govern and communicate with the gods. Later, as Maya society evolved, there was a shift from monarchies to more collective, council-based systems. This transition might be linked to significant migrations, civil wars, and other changes during the post-classic period.

Ed Barnhart also discusses the development of Maya society, with the first signs of Maya culture around 1800 BCE. He notes the interconnectedness of the Maya with neighboring societies like the Olmec and Zapotecs. The Maya's religious involvement deepened as they engaged with the Olmecs to the north. The Maya also created a series of calendars, including the Tzolk'in and the Haab', which were central aspects of their culture and demonstrated their timekeeping sophistication and cosmological beliefs.

The Inca Empire built a vast, complex civilization in the Andes region, characterized by advanced infrastructure, record-keeping, and centralized administration

The Inca implemented a sophisticated "mita" system of rotating labor and communally shared resources that enabled their empire to function effectively

Barnhart explains how the Inca Empire used the mita system, where people took turns working in different roles such as farming or serving in the army. This system facilitated immense infrastructure projects and communal feasts with agricultural excess. The empire also implemented khipu, a complex record-keeping system using knotted strings that encoded not only numbers but potentially language and narrative histori ...

#446 – Ed Barnhart: Maya, Aztec, Inca, and Lost Civilizations of South America

The impact of European contact and colonization on indigenous populations

Ed Barnhart addresses the deep and lasting impact of European contact and colonization on the indigenous populations of the Americas, marked by an immense loss of life and the destruction of sophisticated civilizations.

The arrival of European explorers and settlers in the Americas led to the rapid decimation of indigenous populations through the spread of disease

Epidemics of diseases brought from Europe killed up to 90% of the indigenous people in some regions within the first 50 years of contact

Barnhart emphasizes the tragic consequences of the Columbian Exchange, which saw the Americas receiving 13 infectious diseases from the Old World. This resulted in the decimation of indigenous populations, with an estimated 90% of the 150 million native people dying within the first 50 years of contact. He considers these mass deaths as something that did not have to happen, framing them not as a fair fight but as a tragic calamity. Barnhart mentions that this catastrophic mortality rate among the Maya population underscored the lethal impact of these European-brought diseases.

This catastrophic loss of life resulted in a collapse of traditional knowledge, social structures, and cultural continuity in many indigenous societies

The vast death toll led to an irrevocable loss of knowledge, especially because it was often the elders and young—keepers and inheritors of knowledge—who perished. The surviving generation was left demoralized and half-taught, struggling to maintain their traditions and pass on their knowledge. Barnhart recounts the story of a Spanish priest in the Amazon who unknowingly spread disease among the indigenous people, contributing to the erosion of their society and culture.

Indigenous populations fiercely resisted European colonization, leading to cycles of conflict, subjugation, and the fragmentation of once-powerful civilizations

Groups like the Aztec and Maya faced severe oppression and destruction under Spanish colonial rule, with many of their cultural and religious practices being forcibly suppressed

The European explorers and settlers, such as Hernando de Soto, went through indigenous cities, bringing diseases, utilizing resources, and committing acts of violence. De Soto, noted for his brutality and deceit, ruled through fear and without respect, committing murder and other atrocities against indigenous populations, including burning people at the stake and having his dogs attack them.

The Spanish, encountering the Aztecs during a period of severe drought, witnessed human sacrifice practices, which sometimes included consumption of the individuals killed. On one occasion, the Spanish reacted to one of these ceremonies by locking the doors and slaughtering e ...
