This article presents the results of a coring operation which brought to light new evidence for the evolution of the coastal plain of Aulis (Boeotia, Central Greece) in the Holocene. Thanks to Homer, Aulis is best known as the gathering point of the Achaean fleet before it sailed to Troy and a sanctuary of the goddess Artemis. Ancient sources and archaeological evidence suggest the presence of an ancient marine bay, potentially used as a harbor. In the course of investigation, we drilled two cores, to a maximum depth of 4.20 m in the marshy lowlands and performed mollusc and micro-paleontological identifications, laser grain size analyses, and magnetic susceptibility measurements in order to reveal the facies evolution of the area. We obtained a chronostratigraphy sequence through a series of seven AMS 14C radiocarbon dates. Our study shows that the area was affected by a shallow marine incursion from the first half of the 6th millennium BC and gradually turned into a succession of shallow marine/lagoon environments from ca. 5000 cal. BC to the 2nd Century AD, and into a confined lagoon environment during the Roman and Byzantine periods.  相似文献

A sedimentary deposit discovered at Kerguelen Islands in 1988 is interbedded in the Cape MacLear cliffs, near Mont Rond (Ronarc'h Peninsula). The age of this oceanic deposit is considered to be lower to middle Miocene as indicated by isotopic dating of both the underlying and overlying basalts. This deposit yields a fauna essentially consisting of molluscs (bivalves, gastropods) and crustaceans (cirripedes). This fauna exhibits some similarities to Miocene to Recent austral faunas (New Zealand, Argentina) as a result of the establishment of the Antarctic Circumpolar Current. However, it has no species in common with the extant Kerguelen fauna. The Mont Rond fossil assemblage is best compared with either of two types of extant communities developed on a bare sandy sea floor where infaunal species are dominant, but most likely to an opportunistic one in depths from approximately 10 to 80 m.  相似文献

The article is a critical review of the literature investigating the impact suburbanization has had since the mid-20th century on the downtowns of Canadian mid-size cities and the strategies deployed to revitalize these districts. It demonstrates that large city downtowns are more likely than their mid-size city counterparts to enjoy conditions favourable to their success, hence the need to devise revitalization efforts tailored to the reality of mid-size city downtowns. The article identifies revitalization strategies adopted over the last decades, which mostly failed to reverse the decline affecting these downtowns. It then concentrates on the present, and likely enduring, revitalization model, which emphasizes hospitality, recreation, culture, services, and walkability. The article refines the understanding of the differences between mid-size and large city downtowns by concentrating on their specific dynamics and explores future revitalization options for mid-size city downtowns. It discusses the present and likely enduring absence of alternatives to the present revitalization model and highlights its equity downsides as it challenges the downtown low-income resident living environment.  相似文献

We apply eco-cultural niche modeling (ECNM), an heuristic approach adapted from the biodiversity sciences, to identify habitable portions of the European territory for Upper Paleolithic hunter-gatherers during the Last Glacial Maximum (LGM), circumscribe potential geographic extents of the Solutrean and Epigravettian technocomplexes, evaluate environmental and adaptive factors that influenced their distributions, and discuss this method's potential to illuminate past human–environment interaction. Our ECNM approach employed the Genetic Algorithm for Rule-Set Prediction (GARP) and used as input a combination of archaeological and geographic data, in conjunction with high-resolution paleoclimatic simulations for this time frame. The archaeological data consist of geographic coordinates of sites dated by Accelerator Mass Spectrometry to the LGM and attributed to the Solutrean and Epigravettian technocomplexes. The areas predicted by ECNM consistently outline the northern boundary of human presence at 22,000–20,000 cal BP. This boundary is mainly determined by climatic constraints and corresponds well to known southern limits of periglacial environments and permafrost conditions during the LGM. Differences between predicted ecological niches and known ranges of the Solutrean and Epigravettian technocomplexes are interpreted as Solutrean populations being adapted to colder and more humid environments and as reflecting influences of ecological risk on geographic distributions of cultures.  相似文献

The Port‐Vendres 4 shipwreck is evidence of coastal export trade between Hispania Citerior and Narbonne in 40/30 BC. The cargo is made up of a particular assemblage of Roman wine amphoras (Pascual 1, Dressel 1B and Lamboglia 2) destined for Gallic markets. Archaeological and archaeometric analyses conducted on a selection of the amphoras allowed the provenance of the cargo to be identified as Hispania Citerior and the central‐southern Tyrrhenian coast of Italy. Iluro and/or Baetulo are proposed as the ports of departure, enabling the reconstruction of the trade route and the historical and economic significance of this shipwreck.  相似文献

The principle of reason, that is accounting for all things by referring them to an unquestioned, fundamental principle, commands for Heidegger the total mobilization and universal computation of the world by the technical. The critique of this principle seems to lead Heidegger toward a thinking of the relinquishment of things and an epistemology of innocence, freed from any effect of metaphysical, political, or sociological power. That innocence is however ambiguous. It recalls the Heraclitean play of the child-king and announces the return of a mysterious sovereignty. The power of the technical is warded off for the benefit of another power, not less commanding and absolute, a “superpower” which in its turn could effectively mean, in a still more decisive way than the becoming-technical of thinking, the accomplishment and the end of metaphysics.  相似文献

The burial of a child of two years of age from the 4th century site of Lisieux‐Michelet (Calvados, France) was examined for bone hyperplasia and a variety of mechanical deformations recognized in association with skeletal trauma. Results of DNA analysis of bone using the PCR method identified this child as female. Microscopic features of the teeth (interglobular dentine) and a sample taken from the tibia conclusively determined that this child suffered from vitamin D‐resistant rickets and possibly X‐linked hypophosphataemic rickets as its most common form of occurrence. In addition, evidence for child abuse is suspected based on the presence of cranial and tooth fractures and the appearance of successive plaque‐like endocranial (meningeal) appositions. This is the first palaeopathological report of child abuse in antiquity. Copyright © 2002 John Wiley & Sons, Ltd.  相似文献
