Here is yet another excellent series of lectures released by the Great Courses. I bought this on a whim while it was on sale, and it was an fortunate choice. I was shamefully ignorant of this subject beforehand. Aside from the Maya, the Aztec, and the Incans (none of whom are covered in this course, since Barnhart focuses on the present-day United States and Canada), I could not name any major pre-contact civilizations in the Americas.
Barnhart begins with our hazy knowledge about the first peopling of the continent. The dates are still contested, as is the method that the early migrants used to reach the New World. DNA evidence heavily favors the hypothesis that humans first reached the New World from Asia, though the theory of an Atlantic crossing is still entertained by some. Far less certain is when this first arrival occurred. For a long while it was believed to have been around 11,000 BCE, but potentially older sites have begun to appear.
Barnhart then moves on to the Clovis Tool industry—the first widespread archaeological culture in the Americas—and the contemporary megafaunal extinction (which he believes was not caused by the humans, but by climate change). Then, after reviewing some of the developments of the archaic period (such as the arrival of Corn from Meso-America) we get to the first known city in North America: Poverty Point. Named after a former plantation in Louisiana, this is a massive series of ridges and mounds whose purpose is still not entirely known. To my eye the symmetrical pattern looks as though it must have had a ceremonial function. But people lived there, too—in the thousands—despite the fact that they were not agriculturalists and eating mostly fish and reptiles.
Poverty Point was the harbringer of a series of cultures sometimes collectively known as the mound-builders (though some would say this is a less than respectful way to call them). This includes the Adena and the Hopewell; and as the name suggests, all these cultures made earthen mounds or pyramids. One of the biggest of these, Monk’s Mound, comes from the Mississippian settlement of Cahokia, another important archaeological site. All of these cultures had vast trade networks that interconnected far-flung people, as well as impressive artistic traditions.
Barnhart then shifts his sights to the American Southwest, which was the home to an equally amazing mosaic of cultures across time and space. These civilizations were based on domesticated corn which had come up from the south. Among the people who eked out a life in this difficult environment were the Basket-Makers, the Mogollon, and the Hohokam people—the last of which are known for their massive irrigation networks. The most striking of all were the Ancestral Pueblo people (previously called the Anasazi), who lived in densely-packed apartment-like clusters of buildings with hundreds of rooms. Nobody can see an image of the Cliff Palace in the Mesa Verda national park and doubt that this was an impressive civilization.
More impressive still is the series of ruins in Chaco Canyon: a complex of buildings big enough to house thousands, and yet betraying no signs of mass habitation. Even the stately roads that lead to and from the canyon stop abruptly after some kilometers, without leading to any destination. A ritual use comes to mind as an obvious explanation. And this is reinforced by the solar and lunar orientations of buildings and structures, some of which were designed to let in sharp shafts of light (known as “sun daggers”) at certain times of the year. An archaeo-astronomist, Barnhart takes care to note an awareness of heavenly rhythms, not only here in Chaco Canyon, but in many of the cultures mentioned above.
The lectures end with an overview of the peoples of North America right before contact. Aside from the civilizations in the Mississippi Valley and the Southwest, there were the bison hunters of the plains, the people of the Northwest (famous for their totem poles), and the Algonquians and Iroquois of the Northeast. The final impression is one of amazing cultural diversity and a high degree of sophistication.
In many ways this lecture series did what I hoped Charles Mann’s 1491 would do. Rather than using indirect data to make speculations about pre-contact peoples, as Mann does, Barnhart stays grounded in the archaeological record, firmly tied to what can be deduced from artifacts and ruins. And he does a wonderful job at telling a coherent story from mute and fragmentary evidence. I look forward to his other lecture series on Central and South America.
