Chaco Petroglyph Panel Showing Abstract “Blanket” Designs

Chapter 11 of Crucible of Pueblos, by Rich Wilshusen, Scott Ortman, and Ann Phillips, is called “Processions, Leaders, and Gathering Places,” but I think a more concise description of its main concern is ideology. Specifically, this chapter looks at changes in the ideology of leadership, power, and community organization during the Basketmaker III and Pueblo I periods, as seen through the archaeology of public architecture, the portrayal of processions in rock art, and the reconstruction of related vocabulary through comparative linguistics. Due to this innovative interdisciplinary approach, I found this one of the most interesting chapters in the book. Some of the argumentation and conclusions strike me as either weak or overly speculative, but overall this is a fascinating example of how approaches from very different disciplines can be skillfully combined to produce a more complete picture of the past.

The overall argument in the chapter is fairly straightforward. The authors argue that there were a series of shifts in Pueblo society from the Basketmaker III to Pueblo I periods:

  • The overall settlement pattern shifted from dispersed hamlets to aggregated villages.
  • The locations for occasional ritual gatherings shifted from symbolically important central locations with public architecture to specific locations within villages that in some cases were likely residences of village leaders who exerted control over rituals they hosted.
  • The social ties that sustained communities shifted from personal relationships between individuals to symbolic relationships between abstract corporate entities to which individuals belonged.

The authors see all of these shifts as being ultimately driven by the rapid increase in population from an intensification of agriculture (the so-called “Neolithic Demographic Transition”). The actual evidence for this transition, and its relationship to agriculture, seems a bit thin to me, but at least on a theoretical level it makes sense, and there’s certainly no question that populations were increasing rapidly in the Mesa Verde region (to which this chapter, like several others, essentially confines itself due to the scarcity of comparable data for other areas) during the period they discuss.

From archaeology, the most important shift the authors discuss is the well-known change from dispersed settlements during Basketmaker III to aggregated villages in Pueblo I. (Again, we’re essentially just looking at the greater Mesa Verde area here, without any discussion of the possible Basketmaker III villages at Chaco Canyon.) One aspect of the Basketmaker III settlement pattern that is particularly important is the presence of “isolated” public architecture of presumed ritual function, which in some cases took the form of “great kivas” and in other cases took the form of “dance circles,” the main distinction being whether the structure appears to have had a roof. These structures are generally thought to have hosted occasional rituals that brought in people from throughout the surrounding area and helped to integrate them as a social “community.” In addition to the actual rituals performed, about which we know little to nothing, these events would have provided opportunities to trade, share information, and find marriage partners, all important activities to ensuring the success of the community and its members.

As people began to gather in aggregated villages during the Pueblo I period, the nature of public architecture begins to change. Great kivas are still being used in some villages, but less and less over time, and some villages don’t have them at all. Instead, it appears that some of the integrative functions of the great kivas are being taken over by U-shaped roomblocks with associated “oversized pit structures” that have features suggesting ritual use but, importantly, not in the same way as great kivas. The U-shaped roomblocks appear to have been at least partly residential in function, and they may have served as the residences of emerging village leaders who used the plazas they partly enclosed, as well as the oversized pit structures, to host community rituals that served many of the same functions previously served by great kivas. Unlike the great kivas, however, which appear to have been communal sites not associated with any particular members of the community, these structures would have been under the direct control of the families or kin-groups that owned them, who would therefore have the opportunity to amass ever more status, power, and wealth. There have been suggestions, repeated here, that these structures were the forerunners of the later “great houses” at Chaco and its outlier communities, which seems increasingly plausible as more is known about them. (It’s worth noting, however, that great kivas reappear at Chaco as well.)

So far so good, and this is about as far as the archaeology can take us. These ideas are plausible, but they’re not new. Where this chapter goes further than others, however, is in incorporating evidence from rock art as well. The specific focus is on rock art depicting what appear to be ritual processions. The authors analyze two specific panels in detail. One, from Comb Ridge in southern Utah, is thought to date to the Basketmaker III period and to depict the sort of gathering of dispersed communities at a central ritual site that was argued above to have been typical of this period. The other panel is from near Waterflow in northwestern New Mexico, and it is argued to date to later, after the collapse of the Pueblo I villages in the Central Mesa Verde region but before the rise of Chaco to the south. This site is at a key point along what may have been one of the main routes between those two areas, which may be important.

I won’t go into much detail about the analyses of the two panels, interesting though they are. The main points are that the Comb Ridge appears to depict at least two groups approaching a round great kiva or dance circle site from different directions, possibly reflecting the joining of two previously separate communities into one. The focus is on long lines of human figures, some of which have elaborate regalia or carry possible ritual objects, which may indicate that they represent specific individuals. Referring to an earlier study, the authors suggest that the focus on these rituals in Basketmaker III rock art represents a shift in ideology from earlier Basketmaker II art that focused on life-cycle rituals and individualistic shamanism to a more communal type of ritual associated with the central sites.

There is very little rock art associated with the Pueblo I villages, and no known procession scenes at all. The authors don’t discuss this fact in any detail, but it seems significant as evidence for a shift in ideology associated with the new ritual forms they describe as indicated by the architecture. Yet another shift appears to be indicated by the reappearance of procession scenes during the Pueblo I/Pueblo II transition as represented by the Waterflow panel. Here, the procession is primarily of animals rather than people, and they are approaching a square divided into halves and decorated with abstract designs. The whole panel has much more of an abstract feel, and it includes symbols of authority known from later Pueblo religion such as twin mountain lions who appear to be guarding the square. The authors interpret the square as representing the community, with the animals approaching it possibly being symbols of corporate groups like clans that make it up rather than known individuals. Of particular interest, the authors suggest on the basis of other rock art evidence that the symbols on the square actually represent a specific community, as there are apparently other symbols like this with various abstract symbols that may depict community in a sort of “heraldry” comparable to the city glyphs known from Mesoamerica. There are also intriguing petroglyphs of human figures with these squares as heads, possibly indicating village “heads” or chiefs. This system doesn’t appear to continue into later periods, at least in this form, though it may be worth taking another look at distinctive rock art motifs found at later sites to see if there is any continuity in the symbolism. The so-called “blanket” motifs found in rock art at Chaco are similar at least in form.

So the overall picture from the rock art evidence is of a shift from showing communities as consisting of groups of individual people who gather at a central location on certain occasions to more abstract depictions of communities as consisting of social categories, rather than individuals. This may reflect a further step in the development of community ideology after the first, apparently failed, experiments with village living during Pueblo I. The elaborate system that developed subsequently at Chaco may have been yet another step.

Turning to language, this is a particularly interesting part of the chapter for me given my linguistic background. It is based on Ortman’s dissertation, subsequently turned into a book, which considered linguistics along with other lines of evidence to understand the cultural makeup of the Mesa Verde region in the later Pueblo III period. While several languages from different families are spoken by the modern Pueblos, here the discussion is limited to the Kiowa-Tanoan language family, the only family that is both primarily spoken by Puebloan peoples and complex enough in structure to analyze historically in any detail. The analysis is based on what terms for culturally important items and technologies can be reconstructed to different stages of the language, and how the presence or absence of certain terms relates to when they were introduced in the archaeological record. So, for example, the (Puebloan) Tanoan languages share some terms related to agriculture with the (non-Puebloan) Kiowa language, but lack shared terms for such items as pottery, beans, and the bow and arrow. Since these items were introduced to the northern Southwest in the Basketmaker III period, it appears that Kiowa broke off from the other languages no later than Basketmaker II. The subsequent divisions within Tanoan look a lot shakier to me, but if they do hold up they seem to indicate that the Towa language split off during Basketmaker III, which would have left the language ancestral to Tiwa and Tewa as having been spoken during Pueblo I, possibly in some of the early villages of the Mesa Verde region. Tiwa and Tewa are said to have split after Pueblo I, which the authors of this chapter suggest indicates that it was the collapse of those villages that caused the split.

This is an interesting approach to trying to align the linguistic and archaeological records, and I’m glad people are looking at it. It doesn’t seem to add much to the other two lines of evidence in this specific case, however, and there are some potential issues that make it hard to apply in general. For one, it can be hard to tell if the inability to reconstruct a term to a given protolanguage truly indicates that the item it represents was not present during the period when that protolanguage was spoken, especially in a small language like Kiowa-Tanoan. Terms can be lost in daughter languages in many ways, with the ultimate result being the same in the present language as if it had never existed. However, this is a much more productive approach to the problem of correlating linguistics with archaeology than some others that have been tried, like glottochronology, and it’s definitely worth pursuing to see what insights it can provide.

Another problem, however, is that there are several other Pueblo languages not related to Kiowa-Tanoan, and this type of analysis doesn’t, and can’t, say anything about when and where they might have been spoken. A better approach to try to address the diversity of languages among the Pueblos is to look at loanwords, both between different Pueblo languages and between them and non-Pueblo ones, and try to see what can be inferred about when certain items were introduced to speakers of a given language based on that. There have been some studies along these lines that have given some interesting insights and more work would be useful.

Overall, this chapter is a really interesting approach to trying to correlate different types of analyses to complement each other and get a better answer to a specific question about the past than any one type of analysis individually. At the end the authors call for more work like this, and I second that call. The specific conclusions arrived at in this publication may or may not hold up under further study, but the process it demonstrates for getting them will be helpful in moving forward and getting more complete and reliable answers.
