The effects of geographical distances on pottery assemblage similarities: a case study from Northern Iroquoia

A basic premise of archaeology is that the more frequently two human populations interacted with one another the more similar was their material culture. A corollary of this is that the closer two human populations are to one another geographically, the more frequently they will interact. This corollary has been expressed in the archaeological study of northern Iroquoia since the 1950s on the basis of historical ethnic territories. The expectation has been that after ca. A.D. 1000 to 1300 there was more interaction between village populations within these historical territories than between village populations located in different historical territories. Here I test this corollary with pottery decoration data from 114 northern Iroquoian village sites dating from c. A.D. 1350 to 1640. Results indicate that geographic distance has little effect on pottery assemblage similarity.     

Neutron activation analysis of fine grey pottery from Conimbriga,Santa Olaia and Tavarede,Portugal

The concentrations of two major elements and thirteen trace elements in 73 selected sherds of fine grey ware from the Iron Age and Roman period, excavated at Conimbriga, Santa Olaia and Tavarede, Portugal, were determined by instrumental neutron activation analysis. These concentrations were used to calculate distance matrices which were then subjected to cluster analysis employing SAHN and k-means methods, as well as to principal components analysis, to group the sherds according to the overall similarity of their compositional characteristics. The results showed that equivalent groupings appeared regardless of the taxonomic method used. Two major clusters were recognized corresponding to two different sites, namely Conimbriga and Santa Olaia, suggesting that the ceramics from these sites were made locally. No significant differences in compositional patterns were observed between iron age and roman sherds from Conimbriga.     

Western technical traditions of pottery making in Tang Dynasty China: chemical evidence from the Liquanfang Kiln site,Xi'an city

This study is based on the SEM-EDS and LA-ICP-AES analyses of a sample of twenty-nine Tang sancai sherds unearthed from the Liquanfang site, Xi'an city. The results indicate that ceramics with yellowish bodies are calcareous and those with red bodies were made of ferruginous clays. The use of calcareous clay in Tang sancai bodies is otherwise unknown in Chinese history, which suggests that the technique of Tang sancai making at this site might have been influenced by ceramic technology from the Near East or Central Asia. The paper therefore argues that the traditional approach of treating calcareous clay as the main characteristic of pottery made in the ancient Near East or Central Asia is not necessarily accurate. It is likely that some calcareous Tang sancai ceramics were made in the capital city of the Tang dynasty.     

The multivariate statistical analysis and XRD analysis of pottery at Xigongqiao site

A series of pottery samples excavated from the Xigongqiao site in Tengzhou city of Shandong province was determined using inductively coupled plasma atomic emission spectrometry. Together with excavation data and archaeological analysis, the potential for provenance and technology of unearthed ancient pottery was studied by using multivariate statistical analysis and X-ray powder diffraction pattern (XRD) analysis. In order to characterize and classify these earthenware samples, the major and minor/trace element concentrations were studied with both cluster analysis and principal component analysis. The results showed that there were three different groups in cluster analysis dendrogram in good correlation with their colors. This indicated that the potteries were made from clays of different composition. These results were in agreement with the results of principal component analysis. XRD analysis further assessed the validity of multivariate statistical analysis.     

Re-placing plainware: Production and distribution of domestic pottery,and the narration of the pre-colonial past in the Peruvian Andes

The location of domestic pottery production is central to archaeological narratives. Yet too often, unfounded assumptions are made about place of production, especially in relation to place(s) of distribution and use. Only rarely is this geography of production and distribution explored in detail and with perspective. Here, we investigate this problem in the context of the Peruvian Andes. We present the results of extensive ethnoarchaeological research on the manufacture of domestic vessels in over thirty villages with potters in Northern Peru. Drawing on the ethnographic concept of technical style, we identify three tendencies on the relationships between toolkits, manufacturing techniques, geographic units, and exchange. From these tendencies we develop two models of domestic pottery production and distribution: the local production model and the non-local production model, which are applied in analysis of archaeological materials. While this distinction is apparently simple, we demonstrate how the explicit or implicit use of each of these models has shaped some of the most important debates and issues in Andean archaeology. In sum, we explain how understandings of the manufacture, exchange, and use of plainware impacts narratives about the pre-colonial past.     

The importance of a reliable grouping - Neutron activation analysis (NAA) data of Mycenaean pottery sherds re-evaluated with the Bonn filter method

Using the Bonn statistical procedure to form groups of samples of similar composition and hence origin, published NAA concentration data of Mycenaean pottery sherds from Mycenae and Tiryns measured in Vienna have been newly grouped and, after minor interlaboratory adjustments of a few elemental concentration values, proven to agree with well known Mycenaean patterns measured in Bonn and other laboratories. This demonstrates the importance of a good grouping procedure and also, that data from different laboratories can be used in provenance studies providing a larger reference data base.     

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.     

Elemental analysis of pottery in the study of its provenance: A review

Elemental analysis of pottery is a valuable scientific approach to investigation of its provenance. Increasing use is being made of the approach, and this paper presents a critical review of the basic methodology and experimental procedures. Genenal problems and limitations of the technique are discussed, and the procedures involved in each of the four main stages of such studies are described. These stages are: (1) selecting specimens of pottery for analysis, (2) obtaining samples from the specimens, (3) analysing the samples, and (4) interpreting the results. For each stage, suggestions are made for generally useful procedures and experimental precautions, and for aspects on which further study seems desirable. Much of the discussion is also relevant to the analysis and typing of artifacts of other materials, e.g., metal and stone objects.     

Discontinuing Traditions: Using Historically Informed Ethnoarchaeology in the Study of Evros Ceramics

Ethnoarchaeological studies of pottery primarily focus on the ethnographic present, often disregarding the role of history in the production of material culture. This paper integrates information from historical sources and ethnographic interviews to better understand stylistic ceramic change. Beginning in the 1920s, undecorated pots largely replaced decorated pottery in the region of Evros, Greece. I argue that historically informed ethnoarchaeology provides the key to documenting and understanding the concomitant changes in the social context of pottery production and consumption and the distribution of material culture.

Ceramic production in ancient Nasca: provenance analysis of pottery from the Early Nasca and Tiza cultures through INAA

We report the results of an instrumental neutron activation analysis (INAA) undertaken on a regional sample of pottery from the Southern Nasca Region. The samples included specimens primarily from the Early Nasca (ca. A.D. 1–450) and Tiza (ca. A.D. 1000–1476) cultures from a total of 16 different prehispanic sites. The results of the analysis demonstrate centralized production of Early Nasca polychromes and decentralized production of pottery from the Tiza culture. The results of this analysis confirm previous conclusions about the organization of these two indigenous cultures of the south coast of Peru and support the hypothesis of an excess production of polychromes at the ceremonial center Cahuachi for Early Nasca, and multiple centers of production for the Tiza culture.     

Non-destructive fabric analysis of prehistoric pottery using high-resolution X-ray microtomography: a pilot study on the late Mesolithic to Neolithic site Hamburg-Boberg

The characterisation of prehistoric pottery fragments presents a quite complex task. In provenance studies, petrographic and chemical analyses of the ceramic materials are employed to investigate potential production areas in respect to the geolocial background. Moreover, also the production technology of the firing process, as well as the forming techniques used by the prehistoric potters are of great interest. Their investigation is most often accompanied by a destructive preparation of the samples. In this paper, we want to present high-resolution X-ray microtomography (μ-CT), a non-destructive and non-invasive method, as a supplementary research tool in the study of prehistoric pottery.     

Hermits and hairshirts: the social meanings of saintly clothing in the vitae of Godric of Finchale and Wulfric of Haselbury

Solitary ascetics in the twelfth century were renowned for their ascetic practices, among them the wearing of hairshirts and loricae. These were not merely items of neutral ascetic value but could contain social symbolism. The varying possible social meanings of ascetic clothing are here explored particularly through a comparison of the Vitae of the two well known English holy men Wulfric of Haselbury and Godric of Finchale. The hagiographers of these holy solitaries used their ascetic clothing as one means of highlighting their subjects’ social roles throughout their lives, but it is also argued that the solitaries’ ascetic clothing was perceived during their own lives as marking their distinctive relationships with the world around them, and that these relationships were remembered through miracle stories.

The transport amphorae of Gela: a multidisciplinary study on provenance and technological aspects

Mineralogical, petrographic and chemical analyses were performed on thirty-eight samples of transport amphorae found at Gela, an important Greek colony on the southern coast of Sicily. Based on macroscopic observation, the amphorae, which are datable between the second half of the 6th and the end of the 5th century B.C., were supposed to be local because of similarities to the common wares from the same site. Therefore, in order to verify the provenance of the samples, they were compared to a reference group of locally made ceramics (kiln spacers, kiln wasters, common wares, ancient mud bricks, modern bricks) and twelve samples of local clayey sediments. The results of the analyses have allowed the assignment of all the amphorae to Gela, with the exclusion of five samples, maybe produced in neighbouring sites, and to determine for the first time the archaeometric characteristics of the Geloan medium-coarse ceramics. The aim of our research has also been to investigate some technological aspects of this production, as the location of the clay sources, the methods of clay preparation, and, in particular, the causes of the typical whitening effect on the surface of the vessels.     

Preliminary Provenance Research on Chinese Neolithic Pottery: Huating (Xinyi County) and Three Yellow River Valley Sites

Instrumental neutron activation analysis (INAA) was applied to sherds from the important site of Huating and, for comparison, several Neolithic sites in the valley of the Yellow River. We hoped to compare the compositions of two stylistically different ceramics found at Huating, and to evaluate the degree of compositional clustering and inter‐site resolution that could be expected in an area that is noted for its extensive, and possibly very homogeneous, loess deposits. In addition, pottery sherds from Huating have been examined by microscopic petrography. All of these results will provide needed input in the planning of research towards the formation of a Neolithic/Shang Dynasty ceramic database for future use in archaeological research in China.     

以青州为例看山东的可移动彩绘陶质、石质文物

近十几年来,青州陆续有龙兴寺佛教造像和香山汉墓彩绘陶俑出土。这些文物有一个共同特点,即彩绘保存较好,且数量很大。通过对山东其他地区出土的同类彩绘文物的色彩、纹饰等的统计,让我们对山东的彩绘陶质和石质文物的艺术特色有一个综合认识。陶质彩绘文物自大汶口文化时期出现,经历了由实用器到明器的转变,到两汉时期发展到高峰,中国雕塑的最大特色之一塑、绘结合成熟了,对其后的雕塑艺术产生了很大影响。隋唐以后,彩绘陶质明器渐渐走向衰落。目前彩绘石质文物在山东最早见于汉代画像石,在北朝时期的佛教造像上得到极大发展。继承了汉代陶俑塑、绘结合的雕塑形式,将外来的宗教艺术中国化了,其细腻的刻画,对形体比例的准且把握,使中国的雕塑艺术达到了一个高峰。     

Late Holocene climatic fluctuations and soil genesis in southern Patagonia: effects on the archaeological record

Geoarchaeological research conducted at five localities in southern Patagonia and Tierra del Fuego identified a mollisol within late Holocene aeolian and colluvial deposits associated with archaeological material. The mollisol's origin and development are related to an increase in humidity (c. 1000 BP) following an episode of severe drought during the Medieval Warm Period. Corroborating data is supplied from dendroclimatic and pollen studies. A drastic reduction in frequency of artefact distribution recorded at the sites studied corresponds to this pedologic event, suggesting a greater human presence at these sites during earlier, regional-scale arid conditions. However, the paucity of archaeological remains may also be the result of the low resolution of cultural evidence following the pedologic development due to superimposition over previous archaeological deposits.
