Microarchaeology of a collective burial: cova des Pas (Minorca)

FTIR and phytolith analyses have been used to understand the exceptional preservation of the organic remains at the burial cave of Cova des Pas (Minorca), and to obtain high-resolution data of the plant remains present in the sediments. The presence of sodium nitrate and gypsum suggests a relatively dry environment that has enabled the preservation of the organic material, and contributed to the natural mummification. The dry conditions also favored phytolith preservation. Grass inflorescence phytoliths are abundant all over the site suggesting that phytolith accumulations might have an anthropogenic origin and are related to the burial ritual.     

On the Reuse of Multiscale LiDAR Data to Investigate the Resilience in the Late Medieval Time: the Case Study of Basilicata in South of Italy

The Middle Ages have been traditionally considered a crisis period due to the demographic decrease and economic deterioration occurred in Western Europe. Nevertheless, the historical reconsideration has been focused not only on decline and decay, but also on resilience and recovery which characterized the Europe of the fourteenth and fifteenth centuries. So, today the main open question is as follows: how can we explain the diverse attitude (namely recovery versus decline) and the reasons why some settlements were more (or less) resilient than others? To provide a contribution to this issue, we focused on two medieval villages which are located very close to each other (in the Basilicata Region Southern Italy) and selected because they are characterized by diverse vicissitudes: Irsi abandoned in the fourteenth century and Montepeloso (still “existing” and renamed Irsina) where the population of Irsi moved to. To improve our current knowledge on Irsi, we reused and integrated multiscale LiDAR datasets in order to cope with the lack of documentary source. The use of LiDAR data enabled (i) the reconstruction of the potential urban fabric of Irsi, along with its temporal development and the transformation of the surrounding landscape, and (ii) the definition of a hypothesis about the causes of its desertification based on the inter-site analysis between Irsi and Montepeloso. The main results from the LiDAR-based analysis were as follows: (i) the diachronic reconstruction of the building phases of the village and (ii) the identification of a significant indicator obtained as the ratio between the amount of cultivatable land (close to the settlement area) and the population to characterize the resilience behavior in hilly landscape. This approach has been also successfully applied to another similar case study. Outputs from our analyses pointed out that LiDAR data can fruitfully improve medieval archaeological investigations and facilitate knowledge improvement from intra to- inter-site scale analyses and from local up to a landscape perspective.

     

Early Neolithic funerary diversity and mitochondrial variability of two Iberian sites

An analysis of the burial characteristics of the individuals recovered from two Early Neolithic sites in Navarre (Los Cascajos and Paternanbidea), in the Spanish Basque Country, revealed a complex funerary ritual. The individuals recovered from the Paternanbidea site were distributed in three double graves and a multiple one, while the individuals from Los Cascajos were buried in individual pit-shaped tombs; furthermore, the tombs had a variety of cultural and funerary features. The aim of this study is to evaluate the burial ritual by means of mitochondrial DNA data and the funerary characteristics of 36 individuals recovered from these two sites. The results show that the diversity of these Early Neolithic burial practices from the northern Iberian Peninsula cannot be explained by means of maternal kinship relationships.     

Huerequeque: An inland outpost of the Initial Period Sechín Alto Polity in the Casma Valley of Peru

The Sechín Alto Polity effectively controlled the Casma Valley zone on the Peruvian north coast during the Initial Period (2100–1000 cal b.c.) through an inclusive administrative strategy whereby large inland centers and their component monumental architecture served specific, complementary functions within the polity. Smaller satellite sites established on the coast insured a supply of marine protein to the inland agricultural centers. The political strategy of the Sechín Alto Polity also included expansion inland to colonize the mid-sized site of Huerequeque at a key location in order to annex abundant agricultural land, to access a trade route to the highlands, and to extend and define the eastern Sechín Alto Polity boundary farther. Huerequeque is unique, however, because of its distinct cultural heritage, and excavations there have made it possible to examine the process through which the expanding polity established an administrative presence, imposed Sechín Alto Polity practices, and eventually abandoned the site. More broadly, elucidating this process is critical to a better understanding of the development and expansion of complex societies.     

Comparing expeditious procedures for the seismic vulnerability assessment on the European territorial context: reliability,feasibility, cost,and time consumption

ABSTRACT

The definition of strategies for the preservation and protection of cultural heritage is a topical issue, especially in view of the increasing relevance of the theme of seismic risk mitigation and reduction.

The prediction of the impact an earthquake could have on existing buildings requires the knowledge of their dynamic behaviour. The procedure to be adopted for this purpose is quite complex and onerous in terms of costs, time, and implementation, especially when the study concerns territorial areas rather than single buildings. The definition of methodologies aimed at respecting the principles of economic sustainability and preserving human life and architectural heritage is of paramount importance to assess seismic vulnerability using available resources. Rapid methods for the seismic vulnerability assessment, aimed at defining buildings vulnerability and intervention priority lists, must be implemented to guarantee the preservation of historical centers.

This article describes the application to some case studies of different methods aimed at creating fragility curves for the vulnerability assessment on the European territorial context. The comparison between a deterministic approach and a new probabilistic one is performed for all case studies, to define the most suitable methodology in terms of reliability and savings in cost and time.     

Hallux Valgus among an 18th Century Population of the Canary Islands

Hallux valgus is defined as the lateral deviation of the great toe. It is considered a disease mainly related to the use of boots or shoes that constrict the foot. This process usually ensues along many years and is accompanied by changes at the metatarsophalangeal joint, which serve to make the diagnosis on bare bones. Diagnostic criteria include lateral deviation of the metatarsophalangeal joint (1), lateral subluxation of the first phalanx, degenerative changes of the sesamoid articular facets, and exostosis or remodelling of the medial tuberosity. Following other authors, we have defined hallux valgus as the presence of (1) and any of the other three criteria. In a series of the 18th century burials from the church La Concepción, in Tenerife, Canary Islands, we found 35 cases of hallux valgus out of the 117 cases for which necessary data for the diagnosis could be recorded (29.91%). A significant association was found between changes in the left toe and burial site near the altar, where priests and other people of the high social status were interred.
