How to Make an Unfired Clay Cooking Pot: Understanding the Technological Choices Made by Arctic Potters

Between about 500 a.d. and the late nineteenth century, clay cooking pots associated with the Thule culture were produced in the Arctic region. Ethnographic and archaeological records indicate that these vessels were typically underfired (often even unfired), highly porous, and easily broken. Despite these characteristics, the evidence indicates that they were used to heat water over open fires. In this paper, we examine how Arctic potters were able to produce unsintered vessels capable of holding liquids without disintegrating. We conclude that the application of seal oil and seal blood to the pot’s surface was the key to their success.

Landscapes of the Ghost Dance: A Cartography of Numic Ritual

Recent historical and ethnographic research indicates that the study of ritual behavior could be greatly enhanced by combining parameters of place and landscape use with interpretation of material culture. This strategy is especially useful for identifying the archaeological record of ritual among societies that incorporated topographic features and natural resources into their liturgical order. In this article we apply a behavioral framework to the study of Numic ritual technologies. By intergrating ethnographic and historic data on the geography, practice, and material culture of the nineteenth-century Nevada Ghost Dance, we demonstrate how this framework helps to determine the configuration of a ritual place and its position relative to other ritual and nonritual places.     

Wissen in Geschichten. Zur wechselseitigen Erhellung von Literatur,Medien und Wissenschaft

Knowledge in Stories. On the Mutual Lucidation of Literature, Media, and Science. What are science studies for? The article faces this question by arguing, 1. that they can help to improve literary criticism, and 2. that such an improved criticism allows to recognize how knowledge, whether scientific or not, is linked with history and culture respectively. Both aspects are demonstrated by some remarks on Theodor Fontane's most famous novel, Effi Briest, and its allusions to the then newly discovered microbes on the one hand as well as to mediumistic phaenomena on the other hand.     

Rocks of ages: propagation of hot-rock cookery in western North America

Cook-stone technology's Old-World roots were established by 30,000 B.P. and reappeared in the New World by 10,000 B.P., after millennia of direct-fire cooking. Hot-rock cookery, which is necessary for foods that require prolonged cooking, facilitated land-use intensification by affording greater utilization of nutrients in available foods on a given landscape. This technology gradually diversified during the early Holocene in western North America. By 4000 B.P. its initial intensification was underway; final intensification began by 2000 B.P. and typically peaked during the last 1500 years. Propagation of hot-rock cookery exemplifies pre-Columbian food crises and signals carbohydrate revolutions wherein more high-cost foods feed growing populations. As modeled, cook-stone griddles, earth ovens and steaming pits with rock heating elements are more costly facilities, insofar as fuel is used to heat rocks that, in turn, extend cooking time and temperature. More expensive still is stone boiling, given that fuel heats rocks that, in turn, heat water that cooks the food. Even more expensive in terms of energy expended is the manufacture of heating elements in the form of stone, ceramic, and metal cooking containers, all of which afford further evidence of land-use intensification.     

Composite hunting technologies from the Terminal Pleistocene and Early Holocene,Niah Cave,Borneo

Renewed archaeological investigation of the West Mouth of Niah Cave, Borneo has demonstrated that even within lowland equatorial environments depositional conditions do exist where organic remains of late glacial and early post-glacial age can be preserved. Excavations by the Niah Cave Research Project (NCP) (2000–2003) towards the rear of the archaeological reserve produced several bone points and worked stingray spines, which exhibit evidence of hafting mastic and fibrous binding still adhering to their shafts. The position of both gives strong indication of how these cartilaginous points were hafted and gives insight into their potential function. These artefacts were recovered from secure and ¹⁴C dated stratigraphic horizons. The results of this study have implications for our understanding the function of the Terminal Pleistocene and Early Holocene bone tools recovered from other regions of Island Southeast Asia. They demonstrate that by the end the Pleistocene rainforest foragers in Borneo were producing composite technologies that probably included fishing leisters and potentially the bow and arrow.     

HDOR 410, a mid-Holocene campsite (Hadramawt, Yemen) and the difficulty of determining cultural tradition

Located in Wâdî Mikhfar, Yemen, the stratified site of HDOR 410 was excavated by the French Archaeological Mission in Jawf-Hadramawt. The site illustrates the co-existence of a form of expediency and a form of complexity in the production of lithics, revealing the presence of industries with low technological visibility (expedient production of flakes) at a time traditionally characterised by marked typological constraints (production of trihedral points).
