The importance of tool-class use lives in the formation of archaeological assemblages is established both in theory and empirically, and accurate inference from the material record requires that use lives be measured or estimated with confidence. Unfortunately, no method of measuring use lives directly from archaeological remains has been developed. However, this important quantity may be related to elementary properties of tool classes such as size and weight, properties which are themselves directly measurable. Ethnographic data on ceramic vessels, in which use life is related to such properties, is described and analyzed. Using!Kung San and Ingalik data, a similar analysis is performed for a variety of nonceramic tools and objects, although few of the stone-tool classes common to archaeological assemblages are included. There, use life is related most strongly to manufacturing cost and curation rate, an archaeological measure of which is proposed. Neither is an elementary property, but they can be estimated accurately for many tool classes. These results are noteworthy but not definitive, and they underscore the continued value of museum ethnographic collections and ethnoarchaeological research.

Iconographic, epigraphic, and linguistic data provide new evidence that the tamale constituted the primary maize food of Classic Maya diet. Archaeological and ethnohistoric data pertaining to the tamale and tortilla are reviewed and discussed in terms of the widespread representation of the tamale in Classic Maya epigraphy and art. Iconographic forms of the tamale are isolated and compared with hieroglyphic signs. Glyphs T:14, 39, 86, 130, 135, 506, 507, 754, 577, 584, and 739 are identified as representations of the tamale. Affix T130 contains either of two tamale types, both possessing the phonetic value wa or wah in the ancient script. This syllable provides readings for the Postclassic water group, the action of standing, and an unusual emblem glyph possibly referring to a supernatural region. In addition, the two tamale forms of T130 provide partial readings for the Classic terms for the numbers six, eight, and the name glyph of God N. It is suggested that the tamale constituted an important offering in Classic ritual, and is a principal subject of 819-day cycle texts.

Recent archaeological efforts to model processes of intersocietal interaction have been hampered by a dearth of conceptual tools suitable to these analyses. In particular, there is a need for a theoretical structure that shifts concern from our traditional focus on spatially distinct cultures and their relations to the physical environment. Without such a shift, questions of intersocietal contact cannot be addressed successfully. This article suggests that the concept of social identity has a role to play in this reorientation. The use of social identity focuses attention directly on intersocietal interactions by encouraging us to ask such questions as who is interacting with whom, under what conditions, and what are the effects of the contact on local social change? This paper defines social identity, provides examples suggesting its utility in archaeological research, and considers the specific questions raised by the application of social identity to archaeological materials.

The aim of this review is to introduce readers of American Antiquity to some recent literature in Old World archaeology on the subject of cross-cultural interaction and its role in culture change. The coverage is not representative of Old World archaeology as a whole, but rather focuses on European research, with which this reviewer is most familiar, and primarily introduces literature published in English. It is hoped that readers of this journal may find material in this review that can be of direct use to them in their research on questions of culture change in New World contexts.

Excavations conducted during 1983 and 1984 at the Temple of Quetzalcoatl at Teotihuacan, Mexico, encountered three important burials, including an extensive multiple burial with lithic, shell, and bone offerings. Various lines of evidence suggest that human sacrifices were being practiced on a large scale early in Teotihuacan's history. Moreover, the nature and content of the offerings demonstrate the importance of military aspects in early Teotihuacan society. In addition, other data from excavations at the Old Temple of Quetzalcoatl suggest that religious and political conflicts probably occurred since the time of its construction.

Archaeologists have sought to assess prehistoric pottery production by using hardness as an indicator of the relation between ceramic materials and firing temperature. Yet hardness testing commonly has been limited to a scratch test, which is imprecise and lacks the precision necessary to investigate these relations. Recent research has developed the application of indentation hardness testing for prehistoric ceramics. A sample of low-fired plainware pottery from the Shoofly Village Ruin in Arizona was used as a test case. Results indicate the technique produces continuous scale measurements which are precise and useful for the investigation of intraassemblage variations. The method overcomes many limitations of the traditional scratch test and may be used for either prehistoric or experimental ceramic samples. Indentation hardness testing provides the precision needed to more fully examine the complex relations between hardness and other ceramic attributes.

This paper presents the results of testing technological and techno-functional hypotheses concerning the effects of organic temper. Behaviorally relevant tests are used to compare the performance characteristics of untempered, mineral-, and organic-tempered briquettes and vessels. The characteristics tested include impact resistance, abrasion resistance, portability, thermal shock resistance, ease of manufacture, and heating effectiveness. Organic-tempered ceramics have superior performance characteristics during manufacture, allowing for an expedient ceramic technology. This, along with reduced weight and greater portability, may explain the preference for organic-tempered vessels by groups that frequently shift their residence. Moreover, it is found that all low-fired ceramics, but especially organic-tempered ceramics, are susceptible to complete breakdown in a moist environment under freeze-thaw conditions. Frost wedging is thought to be responsible for an underestimation of Late Archaic organic-tempered ceramics in northern latitudes as well as the destruction of any low-fired pottery subject to a moist depositional environment and freeze-thaw cycles.

This paper introduces a new technique for the quantitative analysis of ceramic thin sections through petrography. The technique is a version of point counting that estimates with considerable precision the amounts of human additives (temper) and natural inclusions (silt and sand) in ceramic pastes. In concert with traditional qualitative identification of mineral inclusions, this technique expands the capacity of petrography to shed meaningful light on such topics in ceramic analysis as technology, production, trade, and classification. To demonstrate the utility of the technique it is used to reassess the taxonomic status of the type Spring Hollow Incised. The results conclusively show that Spring Hollow Incised is much more closely related to a newly defined Early Woodland ceramic assemblage in the Upper Mississippi Valley region than to the Middle Woodland Linn ware to which it originally was assigned.

Blakeslee (1987) has suggested that the Mound Builder myth in part can be traced to John Rowzée Peyton, who reportedly crossed the Great Plains in 1774 and probed a mound, attributing it to a past, non-Indian civilization. However, critical examination of the account, first published in 1867, indicates that John Rowzée Peyton’s adventure actually was invented by his grandson, John Lewis Peyton.

The John Rowzée Peyton book is believed to be an eighteenth-century original with some nineteenth-century additions that probably derive from John Lewis Peyton. This does not affect the episode of the mound excavation in Kansas described in the book in question.

Sullivan and Rozen (1985) suggest that inadequate typologies limit the interpretation of chipped-stone debitage. We contend that the methodology of inference rather than typological structure is limiting debitage analyses. Inferences about the meaning of archaeological data must be derived from sources that are independent of the archaeological record.

Amick and Mauldin (1989) claim that our approach to describing debitage assemblage variation is unproductive because our typology is free of interpretation. They suggest that our method for assigning meaning to archaeological data is sterile because it is based solely on observations of the archaeological record. Their views seem to be based on inattention to key analytic concepts, an unfamiliarity with the full range of factors affecting lithic assemblage content, and an empirically unsupported position about how knowledge of the past may be obtained from the archaeological record. Experimental studies are useful for developing generalizations about how technological factors may influence debitage assemblage characteristics, but sound description of those characteristics is an essential prerequisite to reliable interpretations.

Sullivan and Rozen (1985) attempt to provide an improved method of debitage analysis. We suggest that their article is misleading in a number of ways and fails to address the methodological and theoretical issues under discussion. It is doubtful if their four new debitage categories are "interpretation free," since it now is recognized widely that a theoretical basis necessarily underlies interpretation. Their debitage categories are best viewed as morphological or descriptive groups, with technological correlates which are the expected outcomes of generalized reduction practices. They should not be used in interpretation, since the technological inferences drawn from the four debitage categories are assumed without adequate supporting experimentation on the mechanics of flake fracture. We also reject Sullivan and Rozen"s notion that lithic analysis is best interpreted as a continuum and find the criticisms of so-called stage typologies to be unfounded. Lithic artifacts ultimately should be placed within a product group or step, whenever possible, to facilitate recognition of overall manufacturing practices. Finally, we suggest that the only way to improve the subjective nature of debitage analysis is by example, and we point out where this course is not followed in their study.

Ensor and Roemer (1989) claim that our debitage categories inherently are linked to our interpretations (i.e., are not interpretation free), that we have dismissed unfairly the work of lithic analysts who use stage typologies, and that our view of lithic reduction as a continuum is questionable. In responding, we review the descriptive and interpretive limitations of stage approaches, and explore terminological issues that arise from Ensor and Roemer's zealous adherence to stage approaches. Finally, we reiterate our position that approaches like ours, which seek to describe and interpret distinctive assemblages of lithic artifacts, are more likely to yield productive results than those, such as stage approaches, which focus on identifying distinctive artifacts.
