关于南京明城墙的建造年代,相关史料的记载或有疏漏、或相矛盾、或语义不详,造成了后世对明南京城墙建造年代的多种说法。本文根据史料并结合实地勘察,提出南京城墙建造的起至时间为元至正二十年(1360年)至洪武三十一年(1398年),前后共计39年。 相似文献

Many timber finds lack some or all of the outer, sapwood rings formed in the years just before felling. In order to estimate felling date once the outermost remaining ring has been dated, it is necessary to estimate the number of sapwood rings originally present. Methods doing this for oak are reviewed in the light of an intensive study of living trees at one site and an extensive study of 175 samples from living trees in North Wales and northwest England. Some methods reported in the literature are found to be invalid. A method reported by Hollstein (1965) is most reliable, with modifications for known variations in sapwood number with position in the tree. At present the best available estimate is that a value of 30 sapwood rings be used (95% confidence limits: 19–50). 相似文献

Domestic chickens (Gallus gallus domesticus L. 1758) are one of the most valued farm animals in the world today. Chickens are widespread and economically and socially significant in Africa. Despite their importance, little is known about the nature of their introduction and subsequent integration into African economies. One reason for this is the morphological similarity of domestic chickens to wild galliform birds in Africa such as guineafowl and francolin. Here, we present direct dates and morphological evidence for domestic chickens recovered from Mezber, a pre‐Aksumite (>800–450 BCE) rural farming settlement in northern Ethiopia. Key morphological markers differentiated these domestic chickens from francolins. The Mezber direct chicken element accelerator mass spectrometry (AMS) dates of cal 820–595 BCE and indirect/charcoal AMS dates of cal 921–801 BCE constitute the earliest osteological evidence for chickens in Africa. Chicken bones in the domestic food waste of an early rural settlement at Mezber and their presence in later Aksumite urban contexts show that chickens were integrated into diverse Ethiopian highland settings. The Mezber specimens predate the earliest known Egyptian chickens by at least 550 years and draw attention to early exotic faunal exchanges in the Horn of Africa during the early first millennium BCE. These findings support previous archaeological, genetics and linguistic data that suggest maritime exchange networks with South Arabia through ports along the African Red Sea coast constitute one possible early route of introduction of chickens to Africa.

Foundation deposits underneath the walls of two temples near Semna, Sudan (c. 1500-1480 BC), included dried plant material. Five fruit species are represented: Vitis vinifera (grape), Ficus carica (fig), Citrullus vulgaris (water melon), Phoenix dactylifera (date) and Ziziphus spina-christi. Of particular interest are the remains of tubers of Cyperus esculentus. The plants mentioned above are known as funeral gifts in Egyptian tombs. 相似文献

Examination of fibers from a colored fabric fragment from Seip Mound Group, Ohio, demonstrates the utility of sequencing analytical techniques: (1) minimally destructive pretreatment to remove humic acids followed by plasma-chemical oxidation, in preparation for accelerator mass spectrometric determination of radiocarbon age and (2) direct analysis in real time mass spectrometry (DART-MS) of the pretreatment solution, for the determination of red colorants. Pretreatment followed by plasma-chemical oxidation provided the opportunity to date 3?mg of fiber using just 200?mcg of carbon. Examination of the pretreatment solution by DART-MS confirmed the composition of anthraquinones consistent with those from bedstraw root (Galium sp.). The date determined (1,805?±?35 B.P.) places the textile in the midrange of radiocarbon dates previously obtained for the Seip earthworks; identification of the dye plant shows that the Hopewell possessed a sophisticated knowledge of plants and their uses. 相似文献
