Some Observations on the Ethnography and Archaeology of the American Aborigines
Samuel George Morton (1799–1851)
This study examines the physical and cultural remnants of indigenous American populations, arguing for a fundamental, shared identity among these disparate tribes through the lens of archaeology and physical anthropology.
In Short
This scientific treatise serves as an early attempt to synthesize archaeological findings with ethnographic observations to define the origins of the indigenous peoples of the Americas. By analyzing skeletal remains—specifically crania—and comparing them with architectural patterns and burial practices, the text proposes that all American tribes, from the ancient mound-builders of Ohio to the sophisticated civilizations of Peru and Mexico, belong to a single, distinct race. It stands as a historical record of nineteenth-century intellectual efforts to categorize human diversity through the collection and measurement of material artifacts.
The Story
The inquiry begins with a call to action for travelers and researchers to preserve the rapidly vanishing vestiges of the American aborigine. The author argues that objects once dismissed as curiosities—such as stone tools, burial remains, and pottery—are vital scientific data. The narrative arc moves from this general plea for systematic preservation to a specific examination of two skulls recovered from a mound in Huron, Ohio. These remains, found without any trace of European influence, provide the initial evidence for the author's central thesis: the American "type" is characterized by specific cranial features, such as a rounded head shape, wide cheekbones, and large jaws, which appear consistently across the continent.
As the study expands, the focus shifts to a broader comparative analysis. The author draws upon a vast collection of over four hundred crania gathered from regions as diverse as Chile, Mexico, Florida, and Michigan. By presenting this data, the author asserts that regardless of geography or linguistic differences, there is a "conformable and national type of organization" that suggests a single origin for all these populations. The argument is further bolstered by addressing potential counter-evidence, such as the elongated skulls of the Aymara in Peru. The author concludes that these variations are not biological anomalies but the result of intentional, mechanical deformation practiced during infancy—a cultural tradition intended to shape the head into specific, socially significant forms.
The text then transitions from biological to architectural evidence. By discussing the work of contemporary explorers like John Lloyd Stephens and Josiah Gregg, the author bridges the gap between the monumental ruins of Central America and the humble, modern dwellings of the Pueblo peoples. Through these observations, the author contends that the architectural styles—such as the use of parapets and trap-door entryways—show a direct, linear connection between the ancient "temple-builders" and the modern indigenous tribes of the region.
The final segments address the interpretation of artifacts, such as discoidal stones found in South Carolina, which the author speculates were used for games resembling European quoits. The study concludes by revisiting the practice of cranial compression, detailing the specific, complex bandaging methods used by various tribes to achieve different head shapes. Rather than seeing these as signs of different races, the author frames them as conventional cultural badges. The work ends by reinforcing the notion that, despite the complexity of their social structures or the diversity of their artistic expressions, the American aborigines represent a unified biological and historical population that has been fundamentally misunderstood by those who assume a fragmented or exotic origin.
How It Unfolds
The call for preservation The text opens by emphasizing the urgency of documenting archaeological sites before the progress of modern civilization destroys them forever. It urges researchers to record findings meticulously to build a reliable, cumulative body of knowledge.
The evidence of the crania The author introduces the analysis of specific skulls from Ohio, using their physical measurements to establish a baseline for the "American race." This section serves as the foundation for the claim that distinct anatomical features link tribes across thousands of miles.
The expansion of the dataset The scope broadens to include hundreds of skulls from diverse geographic locations, including Peru, Mexico, and the United States. The author uses this wide-ranging collection to argue that the physical type is consistent across both North and South America.
The interpretation of cultural practices The focus turns to how the indigenous people intentionally modified their appearance, specifically through cranial deformation. The author explains the methods of compression used to achieve specific shapes, framing these practices as evidence of complex social conventions.
The synthesis of architecture and history The study connects ancient, ruined cities with modern Pueblo structures to argue for a continuous cultural lineage. It refutes the idea that the ancient architects were a "lost" race, instead insisting they are the ancestors of modern native populations.
The final classification The work concludes by cataloging specific artifacts, like discoidal stones, and reasserting that all evidence points toward a single, distinct racial origin. It dismisses alternative theories that would classify these diverse groups as anything other than a singular, unified people.
The People
The text is driven by the author, Samuel George Morton, who acts as the primary investigator and judge of his collaborators' findings. Morton is motivated by the desire to prove his "axiom" of racial unity and spends years comparing skeletal structures to validate his hypothesis. He interacts with a network of contributors, such as Mr. Charles W. Atwater, who provides the crucial Huron skulls, and Dr. Blanding, who offers insights into the use of discoidal stones. Morton views these contributors as essential data-gatherers, often relying on their field observations to fill the gaps in his own laboratory-based conclusions. He also engages with the work of travelers like Mr. Norman and Mr. Stephens, often critiquing their interpretations of ruins to align them with his own belief in the continuity of the American race. Throughout the study, the "people" are effectively the indigenous populations themselves, viewed through the objective, sometimes detached, lens of nineteenth-century craniology and archaeology.
In Its Own Voice
"Time and the progress of civilization are daily effacing the vestiges of our aboriginal race; and whatever can be done to rescue these vestiges from oblivion, must be done quickly."
This passage serves as the author's primary motivation for the documentation and preservation of archaeological sites and artifacts.
"I can aver that sixteen years of almost daily comparisons have only confirmed me in the conclusions announced in my Crania Americana, that all the American nations, excepting the Eskimaux, are of one race, and that this race is peculiar and distinct from all others."
This statement summarizes the author’s long-standing, core argument regarding the biological unity of the American indigenous populations.
What It's Really About
The central argument revolves around the scientific categorization of humanity in the mid-nineteenth century. The author seeks to prove that the indigenous populations of the Americas are a distinct and unified race, separate from other human groups. Underlying the entire discussion is a desire to impose order upon the vast, often confusing archaeological record of the Western Hemisphere. By framing architectural ruins and burial practices as evidence of a single, coherent tradition, the author attempts to explain the "bewildering light" of recent archaeological discoveries. The text reflects a moment in history where physical measurement and material classification were treated as the ultimate tools for solving the mysteries of human origins and migration.
Why Read It Today
Readers interested in the history of science will find this a fascinating, if challenging, primary source. It provides an unvarnished look at how nineteenth-century researchers interpreted cultural artifacts and human remains to form theories about race and human development. The prose is precise and clinical, reflecting the author’s background as a physician and his commitment to an empirical, if narrow, worldview.
However, modern readers must approach the text with the awareness that its conclusions are deeply rooted in the racial science of the 1840s. The author’s preoccupation with categorizing human skulls and his assumption that physical shape dictates racial identity will feel alien—and often problematic—to contemporary sensibilities. Furthermore, the reliance on long-debunked methodologies means the book is not a reliable source for modern anthropology. It is best read as a window into the intellectual climate of the nineteenth century, capturing a specific period when scholars were first attempting to reconcile the vast, ancient history of the Americas with their own emerging scientific frameworks. The inclusion of detailed lists of artifacts, locations, and correspondence offers a unique glimpse into the collaborative, albeit limited, world of early American archaeology.
