Creative geographies of ceramic artists: knowledges and experiences of landscape,practices of art and skill

This paper argues for a conception of art as an embodied and creative material practice. It draws on research conducted with seven professional ceramic artists who deal with landscape in their work to explore their processes of art-making through interview and (filmed) observation. It demonstrates the distributed range of embodied and relational more-than-artistic practices which inform how landscape is encountered, known and ultimately represented. It argues that artists’ self-expression in art is based upon material, social and political knowledges which interweave in artists’ lives. By studying ceramicists’ making this paper demonstrates both the non-conscious skill and the conscious technical knowledge needed to make art. It shows chance to have a triple role in practices of making, as something to work alongside, to work against and to draw on as a creative resource. This paper both argues for and demonstrates the value of an approach to art-making that frames it as a complex of both conscious, socio-cultural, technical knowledges and non-conscious skills which together (in)form works of (ceramic) art.     

WHAT IS A SCHOLARLY PERSONA? TEN THESES ON VIRTUES,SKILLS, AND DESIRES

What is the problem that “epistemic virtues” seek to solve? This article argues that virtues, epistemic and otherwise, are the key characteristics of “scholarly personae,” that is, of ideal‐typical models of what it takes to be a scholar. Different scholarly personae are characterized by different constellations of virtues and skills or, more precisely, by different constellations of commitments to goods (epistemic, moral, political, and so forth), the pursuit of which requires the exercise of certain virtues and skills. Expanding Hayden White's notion of “historiographical styles” so as to encompass not only historians' writings, but also their nontextual “doings,” the article argues that different styles of “being a historian”—a meticulous archival researcher, an inspired feminist scholar, or an outstanding undergraduate teacher—can be analyzed productively in terms of virtues and skills. Finally, the article claims that virtues and skills, in turn, are rooted in desires, which are shaped by the examples of others as well as by promises of reward. This makes the scholarly persona not merely a useful concept for distinguishing among different types of historians, but also a critical tool for analyzing why certain models of “being a historian” gain in popularity, whereas others become “old‐fashioned.”     

常熟赵用贤宅无地仗层彩绘的保护研究

赵用贤宅彩绘是江苏明代无地仗层彩绘的重要遗物。为对其进行保护,采用XRD、FT-IR、EDS及视频显微镜等检测分析彩绘成分和结构层次,较为成功地解决了旧木材内油溶性成分极易因溶剂作用带出,部分彩绘上人为涂饰石灰、涂料的去除等技术难点。同时采用接近原胶粘剂性能的复合天然材料(脱色明胶和壳聚糖复配物)加固彩绘,并以溶剂型有机硅材料封护保护。结果表明,保护处理后不仅有效地延长了加固材料的寿命,同时符合可再处理原则。     

Identifying sword marks on bone: criteria for distinguishing between cut marks made by different classes of bladed weapons

Swords have been one of the major weapons used in violent conflicts for much of human history. Certain archaeological situations, especially those dealing with the recovery and analysis of battle casualties, may raise questions about what type(s) of bladed weapon was used in a particular conflict (e.g., the battle of Kamakura, Japan, AD 1333; the battle of Wisby, Sweden, AD 1361; the battle of Towton, England, AD 1461). Little work has been done, however, on developing criteria to differentiate sword cut marks from other types of cut marks, or to distinguish between marks created by different sword types. To develop such criteria, bovine tibiae (n = 7) were struck using six different types of bladed weapon and the resulting marks (n = 92) were analyzed. Eight traits describing the morphology of the cut mark – such as shape, the presence and unilateral/bilateral state of flaking and feathering, the presence of bone shards, associated breaks, etc. – are defined and related to blade type used. Sword marks were found to be easily distinguishable from knife marks. The variation in marks made by different sword types is significantly correlated with differences in blade weight (p < 0.0001), grip (p < 0.0113), and sharpness (p ≤ 0.0179). The criteria and analyses developed and implemented in this study will be of use to researchers in forensics and osteoarchaeology who want to infer bladed weapon type from marks on bones.     

Environmental impacts around the time of Norse landnám in the Qorlortoq valley,Eastern Settlement,Greenland

Palynology, radiocarbon dating, and open-section stratigraphies from archaeological trenches are used to examine the impact of human activity around the time of Norse landnám on vegetation and landscape associated with a small farm (Ø34) in the Qorlortoq valley, Eastern Settlement, Greenland (61° N 45° W). Peat deposits from a mire abutting the Norse ruins revealed a discontinuous palaeoenvironmental record containing a possible hiatus from ca. AD 410–1020. Palaeovegetational data were recovered either side of this period. Pollen assemblages suggest that open Salix scrub dominated the landscape during the pre-settlement phase. The later phases of landnám resulted in the creation of hay fields and heavily-grazed grassy heath. Site abandonment is reflected by a re-expansion of Salix. This occurs shortly before the onset of deposition of a Sphagnum peat, dated to cal AD 1420–1630 (2σ) and reflecting an increase in mire surface wetness, probably in response to a deteriorating climate. Radiocarbon dates were obtained on peat and plant macrofossils sampled from either side of the proposed hiatus at two different but closely-spaced (<20 m) locations across the mire. These produced significantly different dates for the cessation of peat formation in the pre-landnám period (cal BC 2130–1770 and cal AD 240–410 respectively), but near-synchronous dates for the recommencement of peat growth (cal AD 890–1150 for peat and a probably more reliable interval of cal AD 1020–1190 based on plant macrofossils). It is suggested that this hiatus may represent the first direct evidence for peat cutting in Norse Greenland.     

邯郸金代墓葬壁画保护性搬迁及后期修复

2017年7月在邯郸华耀城建筑工地发现一座金代墓葬,经清理后发现该墓葬墓室内存留有大量壁画。作为邯郸地区发现数量较少的文物类型,此壁画的发现对研究邯郸历史文化具有重大价值,因此保留壁画实物十分重要且必要。为此,文物保护修复人员按照文物保护修复规范流程,对壁画进行清理、预加固、加固、分幅、支撑、切割、搬运等操作,将全墓壁画分为17幅,全部搬运回文物库房。2020年6月开始进行后期保护修复,采取对砖体的二次打磨切割、脱盐、加固、翻转、画面层清理、补全、作色等操作,壁画保护修复工作圆满完成。

郑州商代大方鼎拼铸技术试析

早在传说的黄帝与夏禹时期,鼎就被作为重器而地位最尊,具有国祚、国运的象征。郑州商代大方鼎、殷墟商代司母戊大鼎,是这种重器的代表作。郑州方鼎大小两种,小者高81cm,重52kg.大者高87cm,重75kg。司母戊鼎高133cm,重875kg。郑州大圆鼎高77．3cm,重33kg。殷商晚期的铸造技术已发展到很高水平,铸造司母戊鼎这样的重器,是没有太大难题的。然而在郑州商代二里岗上层时期,虽比安阳殷墟仅早百多年左右,铜鼎的形制和缺陷,所呈现的技术确实显得原始得多。就同是郑州商代二里岗上层的食品厂同一个窖藏之内两方鼎,在考察铸造技术时发现…     

Prehistoric Seal Hunting on Lake Baikal: Methodology and Preliminary Results of the Analysis of Canine Sections

A number of archaeological sites on Lake Baikal revealed evidence of Neolithic and Bronze Age seal hunting. A collection of 35 canines from four sites was used to develop a methodology for analysing growth increments of canine dentine for the purpose of examining aspects of prehistoric seal hunting. Results from this preliminary analysis indicate that seal hunting at these sites was a seasonal activity confined to spring and early summer. Baikal seals were probably hunted in early spring for their meat, blubber and furs, and later in the season for their meat and skins.
