The aim of this work is to characterize the original concrete from Roman buildings for public spectacles, theatre and amphitheatre, from Emerita Augusta, Mérida, Spain. An advanced knowledge of the Roman concrete composition is required for a reliable restoration and preservation of these ancient monuments. The concrete was studied through mineralogical (optical polarized microscopy and X-ray diffraction) and petrophysical (bulk and real density, open porosity to water and Hg, mechanical strength and ultrasonic velocity) analyses. With this work, it is possible to fill the gap that exists in this field and the characterization of the materials used in the Roman concrete from these two buildings, never previously studied, despite the significance of this archaeological ensemble, declared a World Heritage Site by UNESCO in 1993. The results allowed us to determine the composition of the Roman concrete and to infer the provenance of the aggregates used in these monuments.  相似文献

Research projects undertaken in the Cantabrian region since 1980 have produced new, high-quality information about the neolithisation process(es) in this area. It is now necessary to review this archaeological information and test the main hypotheses put forward to explain it. This paper presents an update on the archaeological evidence (sites, chronological dates, archaeozoological, archaeobotanical and technological information) for the early Neolithic in the Cantabrian region. It summarizes recent research on neolithisation in the region, and assesses the impact of this process during the early Neolithic, and its later consolidation. Although the available information is still incomplete, it is now possible to identify the focal point of the introduction of elements characteristic of the Neolithic way of life in the region. Current evidence suggests that it is in the eastern sector, where the earliest arrival of domesticates and new technologies such as pottery has been attested. The existence of continuities—such as sustained reliance on hunting and gathering and the coexistence of old and new funerary rites—suggests the persistence of native populations, which gradually participated in the neolithisation process after an ‘availability phase’.  相似文献

Historians’ continuing interest in the origins of the Spanish Civil War has recently extended to the colonial policies of the Spanish Second Republic in Morocco, a relatively unexplored issue in previous decades, which has informed new approaches to the military uprising of July 1936. Foreign sources and archives, however, have been generally overlooked in this context. This article claims that British and French delegates in Morocco made critical observations about republican reforms in Spanish Morocco, which have much to add to this debate. They raised questions regarding the continuity of republican policies in Morocco and the anti-republican attitudes within the Army of Africa. They also challenged conventional knowledge concerning the difficulties encountered by alternative colonial projects in Morocco. In the end, their reports not only questioned metropolitan options but also anticipated the attitudes of the British and French governments, vis-à-vis the military rebellion.  相似文献

Portus Ilicitanus (Picola, Alicante) was the main sea harbour of the Roman Colonia Iulia Ilici Augusta and as such played a crucial role in the supply of fundamental commodities to the Iberian Peninsula. Excavations yielded large quantities of glass in fourth‐ and early fifth‐century contexts. Elemental analysis of 60 samples by laser ablation – inductively coupled plasma – mass spectrometry (LA–ICP–MS) confirmed that the glasses were imported from the Eastern Mediterranean. A majority of the glasses correspond to the HIMTa primary production group, which originates from Egypt. The statistical evaluation of published data of 589 HIMT glasses further revealed differential distribution patterns of the HIMTa and HIMTb subtypes between the Eastern and Western Mediterranean, suggesting chronological trends that are linked to wider geopolitical changes. This demonstrates the need for systematic large‐scale approaches to identify supply patterns and possible factors underlying geographical differences and/or chronological developments.  相似文献

This paper evaluates the impact of accessibility on the productivity of Spanish manufacturing firms. We suggest the use of accessibility indicators of workers and commodities, integrating transport, land use, and individual components, computing real distances or traveling times using the Spanish full road network. Estimated firms’ total factor productivity is explained as a function of the accessibility indicators and additional control variables. Results evidence the crucial role on firms’ productivity to the accessibility of commodities and to a slightly lesser extent the workers.  相似文献

López-Gappa, J., Pérez, L.M. & Griffin, M. February 2017. First record of a fossil selenariid bryozoan in South America. Alcheringa XX, xxx-xxx. ISSN 0311-5518.

Selenariidae Busk 1854 (Bryozoa) is considered endemic to Australia and New Zealand. Here we describe a new species of Selenaria Busk 1854 from the lower Miocene Monte León Formation (Patagonia, Argentina). Selenaria lyrulata sp. nov. is characterized by autozooids with a lyrula-like, anvil-shaped cryptocystal denticle, opesiular indentations and lateral condyles, as well as avicularia with a shield of fused costae. This is the first record of a selenariid bryozoan in South America.

In the small Peruvian, Quechua-speaking town of Chinchero, processes of heritagization of the Pre-Hispanic legacy encouraged by the State and supported by the tourist industry have been trying to create among the population an obligation of historical and emotional identification with their Inca ancestors. This operation has been mainly effected through the territorial transformation of the vernacular space of the Inca ruins into an archaeological site for tourism consumption. The operation has left out other histories grounded in grassroots events, like the struggle for the land against the abusive landowners that took place during colonial times. More than the distant history of the Incas, it is this kind of more recognisable and meaningful folk history what people remember the most and what largely constitutes the fabric of social memory in Chinchero. It is precisely folk history what forms the basis for local heritage values that, unlike what happens with the Inca remains, express intense affective ties with the physicality of other non-archaeological spaces. In light of these developments, the author explores how the people of Chinchero are contesting official versions of heritage and history by foregrounding the emotional power of their own heritage values.  相似文献

This article studies the particular case of the mythological plays of Calderón that form a cohesive and recognizable set of works in certain circumstances. This kind of comedy is modulated by specific issues of reception, under the dominant global principle of playfulness, through the mechanisms of admiratio, and different strategies of courtly game that can be summarized in four basic areas: conventional comicity, the writing of a theater full of sensorismo, the importance of the intellect games, and finally, the strategies to point identity marks of a particular social group.  相似文献

Middle Egypt provides a unique insight into the organization of power, politics, economy, and culture at the turn of the third millennium BC. The apparently easy integration of this region into the reunified monarchy of king Mentuhotep II (2055–2004 BC) was possible because the interests and the local lineages of potentates were preserved. Trade and access and/or control of international exchange networks were important sources of wealth and power then. And Middle Egypt appears as a crossroads of diverse populations, as a hub of political and economic power, as a crucial node of exchanges through the Nile Valley, and as a power center whose rulers provided support to the monarchy in exchange of local autonomy and considerable political influence at the Court. In the new conditions of early second millennium, potentates from Middle Egypt succeeded in occupying a unique advantageous position, not matched elsewhere in Egypt, because of the concentration of wealth, trade routes, new technologies, political power, and autonomy in the territories they ruled.  相似文献
