Elemental Characterization by EDXRF of Imperial Longquan Celadon Porcelain Excavated from Fengdongyan Kiln,Dayao County

A mass of Longquan porcelain shards carved with ‘Guan’ or the dragon patterns were unearthed in the early Ming Dynasty layer of the Fengdongyan kiln site at Dayao County. These celadon shards were fired in the Hongwu and Yongle eras of the Ming Dynasty. In order to research the raw materials and firing technology of the imperial porcelain, 85 typical shards were analysed by energy‐dispersive X‐ray fluorescence (EDXRF). The results indicate that the contents of TiO₂ and Fe₂O₃ in the body vary in the Hongwu and Yongle eras. Compared with Longquan glazes in the Southern Song Dynasty, the average values of K₂O, Fe₂O₃ and TiO₂ are higher, but that of CaO is lower in early Ming imperial porcelain glazes. Principal components analysis (PCA) shows that different degrees of elutriation of the same raw materials are the main reason for this difference in the Hongwu and Yongle periods. However, the raw materials of imperial porcelain glazes show no obvious changes and have inherited the earlier tradition. The production and firing technology of imperial porcelain reached a higher level and had not declined in the Early Ming Dynasty.     

TOWARD A MULTIDIRECTIONAL FUTURE OF HISTORIOGRAPHY: GLOBALITY,INTERDISCIPLINARITY, AND POSTHUMANITY

Compared with the survey offered in the New Perspectives on Historical Writing nearly three decades earlier, historical practices around the world today have witnessed a remarkable change on several fronts. First, marked expansions occurred in such fields as gender history, history of memory, history of knowledge, and visual history, resulting in their noticeable transformation (for example, “gender history” to “history of sexuality” and “visual history” to “history of things”). Second, by exploring and presenting the “other(s)” in modern historiography, new areas are opened up in postcolonial history, global history, emotions history, and so on, which have prompted historians to reconceptualize their notions of time and space. Third, menacing global climate change and notable breakthroughs in various areas of modern technology have exerted an unprecedented impact on historical writing, exemplified by the new developments in environmental history, neurohistory, digital history, and animal history. Science and technology help historians to rejuvenate their research methodology and teaching pedagogy, but they have also demanded that historians acquire a better understanding of the interaction and co-evolution of humans and nonhumans in history, or to take the nonanthropocentric and nonanthropomorphic approach. In sum, what lies ahead for historians and history students today is a multidirectional future, which is at once an opportunity and a challenge.

Local diversity in settlement,demography and subsistence across the southern Indian Neolithic-Iron Age transition: site growth and abandonment at Sanganakallu-Kupgal

The Southern Indian Neolithic-Iron Age transition demonstrates considerable regional variability in settlement location, density, and size. While researchers have shown that the region around the Tungabhadra and Krishna River basins displays significant subsistence and demographic continuity, and intensification, from the Neolithic into the Iron Age ca. 1200 cal. BC, archaeological and chronometric records in the Sanganakallu region point to hilltop village expansion during the Late Neolithic and ‘Megalithic’ transition period (ca. 1400–1200 cal. BC) prior to apparent abandonment ca. 1200 cal. BC, with little evidence for the introduction of iron technology into the region. We suggest that the difference in these settlement histories is a result of differential access to stable water resources during a period of weakening and fluctuating monsoon across a generally arid landscape. Here, we describe well-dated, integrated chronological, archaeobotanical, archaeozoological and archaeological survey datasets from the Sanganakallu-Kupgal site complex that together demonstrate an intensification of settlement, subsistence and craft production on local hilltops prior to almost complete abandonment ca. 1200 cal. BC. Although the southern Deccan region as a whole may have witnessed demographic increase, as well as subsistence and cultural continuity, at this time, this broader pattern of continuity and resilience is punctuated by local examples of abandonment and mobility driven by an increasing practical and political concern with water.     

Tin‐Rich Surface Decoration of Chinese Bronzes: A Case Study of the British Museum Collection

In this paper six bronze artefacts of the Eastern Zhou period to Han dynasty (770 BC ‐ 220 AD) with tin‐rich surface decoration in the British Museum collection were studied using a variety of analytical techniques. The decoration patterns include trellis patterns (菱形纹) on two swords of the Yue state, tiger's striped patterns (hu‐ban‐wen, 虎斑纹) on two swords from the Ba‐Shu region, a hexagonal star pattern (六角星纹) on a spearhead of the Wu state, and a cloud‐like pattern on a garment hook. The tin‐rich decorations on those objects were produced by deliberate tinning processes; at least three different tinning techniques were used, including the use of tin‐rich pastes for the trellis pattern of a Yue state sword and for the mottling decoration on the Ba‐Shu swords, amalgam tinning for the hexagonal star pattern on the spearhead of the Yue state, and hot tinning for the cloud‐like pattern of the garment hook. Different tinning techniques could have been applied to produce similar tin‐rich decoration patterns, and vice versa, a single tinning technique could have been used to produce different tin‐rich patterns on different objects.
