Refining oxygen isotope analysis in the Nasca region of Peru: An investigation of water sources and archaeological samples

The development of complex societies, irrigation agriculture and sociopolitical transitions are of interest to researchers working in the Nasca region on the south coast of Peru. Occupied for thousands of years, many questions regarding the circumstances of these changes in the area are being investigated. Oxygen isotope analysis provides a method for exploring residential mobility of past peoples during these transitions. This study presents new δ¹⁸O data from water sources that would have been used by the ancient inhabitants, providing important information regarding the oxygen isotope variability in the region and the necessary baseline data for migration studies in this region. Our results suggest that the isotopic composition of water sources in the Nasca region is not highly variable. In addition, archaeological human tooth enamel samples from the sites of La Tiza and Pajonal Alto are analysed. The δ¹⁸O_c results of the human enamel samples confirm the local nature of the burial population, as suggested by previous strontium isotope analysis (⁸⁷Sr/⁸⁶Sr).

湖南桃源出土战国彩绘陶器的科学分析

为研究湖南桃源县战国楚墓出土彩绘陶器的组成结构及保存现状,采用能量色散X射线荧光光谱法(EDXRF)、扫描电镜-能谱法(SEM-EDS)、X射线衍射法(XRD)和激光拉曼光谱法(LRS)等手段对陶器胎体成分、表面彩绘、金属涂层等进行分析检测。结果表明:这批彩绘陶器胎体成分相近,为普通易熔黏土。彩绘陶器表面的红色颜料为朱砂(HgS),黑色颜料为炭黑(C)。在彩绘陶壶、陶鼎和陶敦表面发现金属涂层装饰,通过扫描电镜能谱和X射线衍射分析,确定涂层为单质锡,属于锡涂陶的范畴。同时红外光谱测试显示锡层内面棕黑色物质为生漆,可能混合其他胶结材料。以上结果为研究战国时期彩绘陶器,特别是锡涂陶的制作工艺及发展提供了新的资料。     

Illuminated addresses,national identity and Irish sport, 1880–1901

ABSTRACT

This essay examines the cultural significance of illuminated sporting addresses in Ireland at the turn of the twentieth century. Illuminated addresses were used in civic society as a means of commemoration, celebrating retirement and relocation for instance, and they were also physical expressions of public sporting events in Ireland. Illuminated addressees are documents which provide an insight into the cultural histories of late nineteenth- and early twentieth-century Irish sport. This essay pays particular attention to illuminated addresses sponsored by members of the Gaelic Athletic Association and also considers the significance of a late 1890s example which was funded by supporters of the Irish horse-racing which sheds light on the sub-culture of the Irish turf. Illuminated addresses are meaningful documents and this essay recovers, for the first time, some of their hidden history.     

Dama Dentition: A New Tooth Eruption and Wear Method for Assessing the Age of Fallow Deer (Dama dama)

Reliable ageing techniques for wild animals are notoriously challenging to develop because of the scarcity of sizeable collections of known‐age specimens. Without such techniques it is difficult to reconstruct hunting patterns, which is a significant problem for the examination of assemblages from pre‐farming cultures. This paper presents a new method, based on mandibular tooth eruption and wear, for assessing the age of fallow deer. The method was developed from a large collection (n = 156) of known‐age Dama dama specimens, has been blind tested by members of the zooarchaeological community and represents a user‐friendly system with the potential to generate large compatible datasets through which the dynamics of human–Dama relationships can be examined.
