Questioning Craft Production at Angel Mounds Analysis of the 2006–2009 Angel Mounds Field-Schools

Abstract

Seventy years of archaeological investigations at the site of Angel Mounds (12VG1) have led to a broad overall understanding of the cultural practices of the Mississippian people in southwest Indiana nearly 1,000 years ago, but have also raised ever expanding new questions. Recent field-school excavations at Angel Mounds, sponsored by the Glenn A. Black Laboratory (GBL) at Indiana University, explored magnetic anomalies in a previously unexcavated area at Angel Mounds. Analyses of features and artifacts encountered during the excavations at Unit A (the “Potter's House”), including large amounts of Mississippi Plain pottery and craft-production objects, inspired new questions on the organization of craft production at Angel Mounds and other Mississippian archaeological sites. In this article, I test whether a structure at Unit A may have been a craftproduction workshop by reviewing data archaeologists traditionally associate with workshops and examining the standardization of pottery found at the location. Preliminary results demonstrate the variability of Mississippi Plain pottery, even within single locations, and also show the potential analytical utility of such variability for testing important issues in the archaeology of Mississippian societies, including supposed elite-control over craft production and intrasite social organizations.     

The Timing of Angel Mounds Palisade Construction A Search for the Best Chronological Model

Abstract

Angel Mounds was a heavily fortified Mississippian settlement with several discrete palisades. Although the palisades were identified early on, the construction sequence has remained elusive because the construction episodes do not have stratigraphic relationships with one another. Recent work at the site reexamined old test excavations and collected new material for radiocarbon dating. AMS dating yielded a suite of new dates from palisade contexts. To refine the construction sequence, five Bayesian chronological models were constructed for palisade building. These models indicate that palisades were first built at Angel Mounds sometime between A.D. 1278 and A.D. 1410, which precedes or coincides with regional depopulation in the lower Ohio River valley. These results further indicate that palisade building at Angel Mounds may be a consequence of external competition and conflict caused by resource-induced stress resulting from deteriorating climatic conditions.     

Patterns of Faunal Utilization and Sociopolitical Organization at the Mississippian Period Kincaid Mounds Site

Archaeologists have debated the degree of complexity at Mississippian period polities with some arguing that they were highly stratified and centralized and others arguing that they were politically decentralized. Faunal analyses from the Cahokia Mounds and Moundville polities have been used to suggest that there were significant differences in the foodways of elite and nonelite peoples and that deer remains were part of redistributive economies. In this article, I discuss the distribution of faunal remains from five archaeological contexts at the Kincaid Mounds site in southern Illinois. In particular, I explore species diversity and the distribution of deer body parts using utility indices and anatomical units and compare these results to Cahokia Mounds and other Mississippian period villages in southern Illinois. The distribution of taxa and deer elements from both the mound- and nonmound-related contexts at Kincaid follows patterns of possible elite consumption at Cahokia and restricted use of rare species.     

Uniform Probability Density Analysis and Population History in the Northern Rio Grande

One of the basic challenges facing archaeology is translating surface evidence into population estimates with sufficient chronological resolution for demographic analysis. The problem is especially acute when one is working with sites inhabited across multiple chronological periods and the production curves for pottery types are unknown. In this paper, I present a Bayesian statistical method which I call uniform probability density analysis that is tailored to this situation. This method combines uniform distributions derived from the local pottery chronology with pottery assemblage data to reconstruct the population history of individual settlements. I also illustrate applications of this method at the site and regional level using data from Cuyamungue and the surrounding Tewa Basin/VEP II New Mexico project area. The results allow one to identify a period of significant population movement corresponding to the period of Tewa ethnogenesis in the thirteenth century CE.     

The Latest Objects from Silchester,Hants

THIS paper brings together for the first time a selection of medieval glass and pottery distilling-vessels from British sites. A discussion on the technical aspects of distilling by F. Greenaway (Part I) is followed by a report on two important groups of glass and pottery distilling-apparatus from Selborne and Pontefract priories of the middle and late 15th century respectively (Part II). Part III discusses pottery distilling-vessels from other finds in Britain. Two types of pottery alembic are distinguished and their use in association with bases of either furnace or bowl type is suggested; industrial bottles connected with distilling are also briefly considered. The survey has brought much information to light but has also left many problems unanswered. Coordination of documentary research into techniques, archaeological recognition of vessels, and the chemical analysis of residues is necessary before firm decisions can be made about the uses of the vessels and the types of unit required for specific operations. It is hoped that this paper will stimulate further work in this field.     

Statistical tool for dating and interpreting archaeological contexts using pottery

Analyzing chronological patterns is one of the major issues in archaeology. How can the date of a specific context be estimated? Is it possible to identify residual and intrusive material in it at the same time? Numerous statistical methodological approaches have been developed and implemented to estimate dates but have less often addressed the issue of socio-economic area or the functional interpretation of contexts. This article deals with the construction and analysis of two different probability estimate density curves of context dates using pottery. By contrasting the two curves we can define the boundaries of the socio-economic area and make a chrono-functional interpretation of a context. This statistical tool allows the archaeologist to visualize and analyze chronological patterns easily. The method is applied to the analysis of contexts in the town of Tours in particular and more generally in the centre-west of France, based on collected pottery finds.     

Physical and Geochemical Characteristics of Soils from Angel Mounds State Historic Site,Indiana, including a Case Study of Sherds from Unit A

Abstract

Using physical and chemical characteristics of soil to evaluate archaeological artifacts and their preservation potential along with associated features is well established. The soil characteristics and geochemistry of the Angel Mounds site (12Vg1) indicate the soil geochemistry is very homogenous and composed of loams and silt loams with a range of pH values from 4.69 to 6.17, mean value of 5.40 ± 0.47. The slightly acidic nature of the soil favors the preservation of pollen and soil diatoms, with minor corrosion potential for the bone, shell, and sherd artifacts. A comparison of the geochemistry of the soils from Unit A and site-wide sampling to sherds from Unit A suggests that elevated phosphorus (P) in the sherds is either the result of the addition of a P-rich temper material or from the sourcing of nonlocal clay-rich sediment, and not from use-derived residue or from the soils themselves.     

Fort Ancient-Mississippian Interaction and Shell-Tempered Pottery at SunWatch Village,Ohio

Abstract

The use of mussel shell for tempering pottery vessels by Fort Ancient societies is poorly understood. Suggestions have included both diffusion from neighboring Mississippian social groups and local developments, although no studies have investigated whether shell-tempered pottery is non-local or associated with Mississippian features and artifact types within Fort Ancient sites. This study begins to remedy this deficiency by examining the social and temporal contexts and petrographic composition of shell-tempered pottery at the Sun Watch site, a Fort Ancient village located in sw Ohio that was occupied during the height of neighboring Mississippian developments (ca.A.D. 1150–1450). Our findings indicate that shell tempered pottery was not produced locally and is linked with a village leader and Mississippian-inspired architecture.     

夹砂陶器掺合料的初步研究

夹砂陶是陶器中非常重要的一个品种,特别是作为炊煮器是古人生活中不可或缺的日用器具。对夹砂陶器中掺合料的研究能够反映当时夹砂陶的制作工艺,也可以用来探讨掺合料的来源以及当时手工业分工以及产品的流通等问题。为此,本研究主要利用显微共聚焦拉曼光谱分析等技术手段对河南灵宝西坡遗址出土夹砂陶器中人工分离出的掺合料进行了初步分析,讨论了其中掺合料的类别、所占比重及来源。结果表明,西坡遗址出土的红褐色夹砂陶中掺合料的矿物成分主要以长石、石英、云母为主,而对样品及砂粒的称重结果表明,一些样品所用掺合料的比重可达20%左右。同时,对该遗址出土石料的分析表明,石料的物相组成与掺合料相似。另外,结合对良渚古城遗址夹砂陶器的分析结果,提出古代夹砂陶器的掺合料很有可能一部分来自于当时石器和玉器等加工废料的论断。研究成果为今后有关陶器掺合料的研究提出了新的方法和思路,同时也为探讨古代手工业生产的专业化模式提供依据。     

THE DISCOVERY OF ANOMALOUSLY HIGH SILVER ABUNDANCES IN POTTERY FROM EARLY ROMAN EXCAVATION CONTEXTS IN JERUSALEM*

This is the first study on the differential distribution and concentrations of silver in ceramics recovered from archaeological excavations. The chemical compositions of 1174 pottery vessels from 38 Roman‐period sites in Israel have been determined. Unusually high and variable abundances of silver were discovered in pottery samples of all vessel types and chemical compositions from four distinct archaeological contexts dating to late first century bce to 70 ce Jerusalem. The large majority of the Jerusalem vessels could be distinguished by their silver abundances from all analysed pottery pieces recovered at rural sites outside Jerusalem, even when the pottery types and chemical compositions, except for silver, of pottery found within and outside Jerusalem were indistinguishable. The evidence is suggestive of a human origin for the high and variable silver abundances, and dispersion of the silver by aqueous transport. The differential silver concentrations found in excavated pottery from Jerusalem and other urban and rural sites suggest that attention to the distribution of silver in pottery from excavated contexts may be helpful for evaluating the nature and function of archaeological remains and patterns of urban contamination.     

Ceramic form and function in the Neolithic Gulf. A view from Bahra 1

This paper discusses the possible functions of ceramic vessels in the Neolithic Gulf, based on new data from the Ubaid-related settlement of Bahra 1 (Kuwait). Two pottery groups identified at the site—Ubaid Ware and Coarse Red Ware—are found in great numbers and variety of forms which provides grounds for a reconsideration of the role of pottery vessels in the societies of the Gulf. Analysis of this material reveals a more varied function of pottery vessels compared to that suggested in earlier studies. It was also possible to define the function of certain pottery vessels in more detail, both in their economic and social context.     

The mineralogy and petrography of Low Lands Ware 1 (Roman lower Rhine–Meuse–Scheldt basin; the Netherlands,Belgium, Germany)

Over the last 80 years Belgian, Dutch and German archaeologists working in the lower Rhine–Meuse–Scheldt basin have encountered a Roman pottery group that occurs in large quantities at most Roman sites in the region. Several researchers have separately tried to define this pottery, resulting in different names. Petrographic and geochemical analyses of 100 samples have now shown that the production of this ware predominantly made use of one source of raw material, divisible into three sub-groups on the basis of technological choices. The probable source lies in the early-Pleistocene Tegelen-formation, a clay rich in muscovite mica and garnet, which outcrops in the tertiary Scheldt escarpment (Nl) and the campine microcuesta (B). On the basis of geographical characteristics, Roman finds and the presence of a large Medieval pottery industry, production in the Bergen-op-Zoom area is suggested. In view of these new findings the name ‘Low Lands Ware 1’ is introduced to refer to this pottery group.     

The Pottery of Khirbet En-Nahas: A Rejoinder

Abstract

Smith and Levy (2008) have published an assemblage of pottery from the copper production centre of Khirbet en-Nahas in Jordan. Based on their interpretation of the ¹⁴C dates from the site and contra the accumulated knowledge on the ceramic typology of the Levant they argue that this pottery dates to the Iron I and Iron IIA, and that there was no later activity at the site. We show that much of the Khirbet en-Nahas pottery dates to the Iron IIB–C. We argue that the charcoal samples sent for radiocarbon dating originated from the waste of industrial activity at the site in the Iron I and Iron IIA, while the pottery came from a post-production activity in the Iron IIB–C — an activity that included the construction of a fort on the surface of the site. We propose that the fort was built along the Assyrian Arabian trade route, at the foot of the ascent from the Arabah to the Assyrian headquarters of Buseirah.     

Gabbroic clay sources in Cornwall: a petrographic study of prehistoric pottery and clay samples

Summary.  This analysis of prehistoric pottery and clay samples from Cornwall demonstrates that the clay used to make Cornish gabbroic pottery in prehistory originated around the gabbro rock outcrop in a small area of the Lizard peninsula. The research uses petrographic and chemical analysis to subdivide the prehistoric pottery into six groups. Owing to the unusual geology of the Lizard these groups can be attributed to specific locations. The most abundant pottery fabric, Typical Gabbroic , was made using coarse clay which is mainly found in a 1 km² area near Zoar. A finer version of this clay, found higher in the soil profile or slightly transported and redeposited, was used to make Fine Gabbroic pottery and an even finer variant called FNS (Fine Non-Sandy) Gabbroic . We identify for the first time here a Loessic/Gabbroic pottery fabric which can be matched exactly to clay found at Lowland Point. Serpentinitic/Gabbroic pottery was made using clay from the gabbro/serpentinite border zone. Pottery made from the Granitic/Gabbroic fabric did not match any clay from the Lizard, showing that gabbroic clay was sometimes removed and made into pottery elsewhere in Cornwall. The main clay source near Zoar was used for clay extraction throughout the Bronze Age and Iron Age for pottery which was traded all over Cornwall. Other gabbroic clay sources produced pottery only during certain periods and exclusively supplied particular settlements, such as the Loessic/Gabbroic fabric which was found only at Gear and Caer Vallack. The results suggest that pottery was produced by several small-scale cottage industries, which may have operated on a seasonal, part-time basis and probably formed only part of a wide range of activities located around the Lizard area.     

PETROGRAPHIC AND GEOCHEMICAL EVIDENCE FOR LONG‐STANDING SUPPLY OF RAW MATERIALS IN NEOLITHIC POTTERY (MENDANDIA SITE,SPAIN)

Pottery from the Neolithic Mendandia site has been studied. The radiocarbon dating of the site corresponds to a range of dates from 7488–7546 cal bc to 5283–5437 cal bc : the first occurrence of pottery is dated at 5968–6040 cal bc for the lower level III, and up to 5386–5560 cal bc for level II. The antiquity of the potsherds places them within the oldest pottery production sequences in the Iberian Peninsula, which adds to the interest of this study. Ten potsherds from level II and five from level III are analysed for their petrographic and chemical characterization. The petrographic data show two different methods of raw materials manufacture—intentionally tempered pottery (ITP), using calcite and/or limestone and grog, and naturally or non‐intentionally tempered pottery (NTP). According to the matrix paste features, on the basis of the amount, shape, and average or size range of the mineral inclusions, clayed (type A) and sandy (type B) paste types were established and related to two different source areas. The chemical features also indicate two raw material sources and are in agreement with the petrographic paste types. The absence of significant chemical and mineralogical differences between the pottery from levels II and III suggests two contrasting areas for raw materials supply that lasted for at least 600 years.     

The persistence of caffeine in experimentally produced black drink residues

Black drink is a native North American caffeinated tea produced from the leaves of Ilex vomitoria. The beverage was an important part of prehistoric Southeastern culture, as it was the only native source of caffeine in North America. The leaves of I. vomitoria were, therefore, a potentially valuable trade resource during the period. As such, the ability to identify archaeological black drink residues is useful to Southeastern archaeologists. In order to determine the plausibility of detecting I. vomitoria in residues, black drink was repeatedly produced in experimental unglazed pottery. The resulting potsherds were buried in several environmental contexts, recovered, and underwent absorbed pottery residue analysis. After two months of burial in three different soil types, plus a control stored in the freezer, caffeine was well-preserved in all sherds, suggesting that caffeine is a potentially useful biomarker for the detection of black drink.     

Anglo‐Saxon Style Pottery from the Northern Netherlands and North‐Western Germany: Fabrics and Finish,Regional and Chronological Patterns,and their Implications

This paper presents the results of a study of Anglo‐Saxon style pottery in the northern Netherlands and north‐western Germany, involving macroscopic and microscopic analysis of fabrics and finish. Both regions show similar developments in form and decoration in the pottery of the fourth and fifth centuries ad , the late Roman and Migration period, resulting in the typical decoration and shapes that are known as the Anglo‐Saxon style. In the northern Netherlands, this style is traditionally associated with Anglo‐Saxon immigrants. It has, however, been suggested that this style was, rather, part of an indigenous development in areas in the northern Netherlands where occupation was continuous, though influenced by stylistic developments in north‐western Germany. That hypothesis is supported by the analysis of fabrics and finish presented here. The characteristic of fabrics and surface treatment indicate technological continuity. The use of local clay sources for Anglo‐Saxon style pottery and for contemporary regional types indicates that most of the Anglo‐Saxon style pottery in the northern Netherlands was not brought by Anglo‐Saxon immigrants or as imports, but must have been made locally. That applies to settlements with continuous habitation, as well as settlements in the coastal area that were not inhabited during the fourth century ad .     

PETROGRAPHIC MODAL ANALYSIS - A NECESSARY COMPLEMENT TO CHEMICAL ANALYSIS OF CERAMIC COARSE WARE

Bulk chemical analysis is shown to be insufficient for the archaeometric interpretation of coarse ware pottery. Accompanied by quantitative petrographic analysis of the temper much more conclusive information can be obtained at little more expense. Three small groups of prehistoric pottery from Switzerland have been examined with both techniques, showing that expensive chemical bulk analyses may be obsolete or even misleading, and in any case need further confirmation and interpretation by petrographical means. Assuming a rigorous sampling strategy, the number of analyses necessary for valid statements can be substantially reduced relative to those necessary for the statistical interpretation of bulk analyses only.     

Pottery Styles during the Early Jomon Period: Geochemical Perspectives on the Moroiso and Ukishima Pottery Styles

Energy‐dispersive X‐ray fluorescence (EDXRF) was used to determine the minor and trace element chemistry of 92 Early Jomon pottery sherds. The sherds came from four contemporary sites in the Kanto region and belong to either the Moroiso or Ukishima style of pottery. Principal components analysis (PCA) and discriminant analysis indicate that there are four major groups in the data set, which correspond to site location. Furthermore, for sites having both Moroiso and Ukishima pottery, the statistical tests indicate that both styles of pottery were made from the same or geochemically similar raw materials. This suggests that both styles were probably made at the same site, and indicates that if the different pottery styles are reflecting ethnic identity, then intermarriage between ethnic groups is occurring. Alternatively, the pottery styles could be reflecting some sort of social interaction between groups.     

Understanding ceramic variability: an archaeometrical interpretation of the Classical and Hellenistic ceramics at Düzen Tepe and Sagalassos (Southwest Turkey)

Within the aim of contributing to the artisanal craft history at Sagalassos (SW-Turkey), an archaeometric programme including thin section analysis, ICP-MS and multivariate statistics was developed to define the variability on a provenance and/or technological scale of the Classical/Hellenistic ceramic assemblage of Sagalassos and Düzen Tepe. The obtained data were used to evaluate the extent and variation of local pottery production. Petrographic and geochemical analysis as a grouping technique proves to be conditional for documenting the variation in ceramic wares present on both archaeological sites. Elemental evidence supports local production activities between Classical and Hellenistic times, documenting a deliberate change in treatment of raw materials during the Late Hellenistic period in function of ware groups.
