The toponym Kerend has a long history. This study explores the appearance of Kerend in pre-modern sources, beginning with the toponym Karinta? in the late second millennium BC. Kassite, Elamite and Assyrian rivalry for control over the central western Zagros mountains is discussed and the survival of the name in later antiquity is investigated. A derivative of the name appears in Claudius Ptolemy’s Geography and in the Parthian Stations of Isidore of Charax, as well as in the late Antique Cosmographia of the Anonymous Geographer of Ravenna. A homonymous name from the area east of the Caspian Sea is also discussed, as are several unrelated names occurring in other sources (Achaemenid Elamite, Armenian). 相似文献

The death of the Persian dynast Rostam b. Farrokh-Hormozd at the Battle of al-Qādisiyyah during the Arab-Islamic conquest of Iran received much attention in both the Islamic conquest literature and the Persian epic tradition canonized in the Shāh-nāmeh. A careful examination of the narratives of early Islamic history teaches us much about the mindset of those living in the first centuries following the momentous events of the seventh century. By removing the layers of literary embellishment and moralistic exegesis, we can understand better the impact of the death of this Sāsānian dynast. In addition, by comparing the narrative traditions, we can uncover valuable testimony regarding the early development of what might later be described as an Islamic Iranian identity. 相似文献

Ethnoarchaeological research combined with morphological analysis of modern and ancient grinding stones was completed in 2013 and 2014 as part of the Eastern Tigrai Archaeological Project (ETAP), based in the Gulo Makeda region of northern Ethiopia. Research focused on investigating the cultural context of grinding, grinding stone morphology, and use-surface area employing low power use-wear analysis of grinding surfaces. In the Gulo Makeda region today, men manufacture grinding stones and women use them in food processing for many hours per day. While grinding, relationships are formed and maintained with other women, and archaeological evidence suggests that women were grinding together in the past. It was discovered through interviews that distinctive grinding surfaces are preferred for processing different cereals based on grain size. Rough surfaces are used to process larger grains such as imported Near Eastern barley (Hordeum vulgare), wheat (Triticum spp.), maize (Zea mays), and the African domesticate sorghum (Sorghum bicolor), while fine/smooth surfaces are used for smaller, locally domesticated African grains including finger millet (Eleusine coracana) and t’ef (Eragrostis tef). Comparing ethnoarchaeological data with evidence of different use-surfaces on ancient Mezber grinding stones suggests that both locally domesticated and imported grains have been processed in the region for thousands of years. Interpretations are made about the use of grinding stones in the past through analogy, supported by evidence of ancient stone tool morphology and surface wear. The archaeological record at the pre-Aksumite site of Mezber indicates that grinding stone sizes have changed through time, with larger grinding surface areas likely reflecting the need for the production of greater amounts of flour. 相似文献

The state of Louisiana is widely recognized for the Creole and Cajun cuisines of south Louisiana. Yet several Indo-Spanish foodways have been preserved in northwest Louisiana since the colonial era. In this paper, we explore the tamale-making traditions of three distinct culture groups who reside in the region and how traditions are a source of ethnic identity. Tamales are primarily associated with residents of Indo-Spanish heritage in Sabine Parish, but they are also part of the foodway traditions of the French Creoles and Cane River Creoles of Natchitoches Parish. It is asserted that the tamale-making traditions in these communities resulted from a process of creolization that took place during the eighteenth century with the start of European colonization. We assess the role of tamale-making among contemporary cultural groups to demonstrate how this tradition has survived in the region. 相似文献

Evidence for the conflict between two rival candidates for the bishopric of Rome following the death of Zosimus at the end of 418 comes from a group of twenty‐five letters, most of which are official letters to and from Emperor Honorius (the rest being from other imperial officials and the emperor's sister), all but one of which are found in the Collectio Avellana. Interestingly, we have nothing preserved from the two episcopal claimants about this matter. The group of letters chronicle imperial concern for the preservation of public order. Do we have here an example of imperial interference in episcopal elections in Rome? In this article a careful examination of the letters reveals that Honorius was concerned only that the Roman church's procedures had been followed (Collectio Avellana, Ep. 15), which should determine who was lawful bishop. Sociological Conflict Theory is employed to investigate the nature of the evidence to address issues of the nature of the dispute and its participants, what values were contested, how it escalated, and how it was resolved. Such an approach makes clear that our evidence focuses on the role of the emperor and only incidentally tells us of the thinking and strategy of the two candidates. The final decision was made not on the merits of the candidates and the legality of one of the two elections, but upon Eulalius' violation of the conditions imposed upon the two rivals while the dispute was to be settled. Despite the emperor's concern only to facilitate the church settling this conflict itself, in the end it was an imperial measure that determined the outcome of the disputed election. 相似文献

We studied the composition, colour chromaticity and form of application of red pigments in human bone samples from seven Classic period Lowland Maya sites. The samples were analysed by X‐ray diffraction, scanning electron microscopy (SEM) and X‐ray energy‐dispersive spectroscopy (EDS). Colour was measured using conventional colour identification standards (Munsell) and reflectance spectroscopy. Cinnabar and hematite were identified as the pigments used. We conclude that the reflectance method has advantages over conventional visual results, as it provides precise, objective and quantifiable optical data to distinguish the chromaticity, colour saturation and brightness of the pigments. 相似文献

Bells of copper and copper alloys and gold–copper alloys were deposited in events at the Cenote Sagrado at Chichén Itzá, Mexico during the site's primary occupation (ad 750–1050) and in later centuries. Housed in three museums in the United States and Mexico, bells (n = 38) were evaluated for traces of fabrication and alteration using Vis–UV–IR optical microscopy. Bulk compositions were determined through p‐ED‐XRF. Phases and compositional variation by depth were characterized through XRD and RBS. The technological styles of bell groups were ascribed to communities of metallurgical practice, from West and Central Mexico to Costa Rica and Panama. 相似文献

This contribution focuses on the study of historical mortars from a Roman archaeological site known as Villa dei Quintili, a monumental villa located in the south‐eastern part of Rome (Italy). The study was carried out on 38 mortar samples, collected from several edifices within the complex. A multi‐analytical approach, including polarized optical microscopy, scanning electron microscopy coupled with energy‐dispersive system and laser ablation inductively coupled plasma mass spectrometry, was used to analyse the pozzolanic material used for the preparation of mortars. Data obtained on both major and trace elements were compared with the compositions of Pozzolana Rossa, Pozzolana Nera and Pozzolanella samples from the Alban Hills volcanic district, collected from a historic quarry nearby, as well as with literature data. The results of such a multidisciplinary approach allowed us to recognize the use of all three pozzolan types for the aggregate fraction of examined mortars from the Villa dei Quintili. 相似文献
