Biostratinomy of terrestrial macromammals in Doñana National Park (Spain)

  • Bernáldez Sánchez, Eloísa
There is no scientific guarantee that vertebrate remains preserved in archaeological and palaeontological sites are a representative sample of the palaeocommunity they belonged to, or that they formed a part of the preferences of man consumption since they are mainly waste deposits. We do not know the qualitative and quantitative consequences of pre-depositional processes of trophic activity of human population and of any other carnivore and scavenger that could have affected them. As a consequence of this, we performed a biostratinomic study of the carcasses assemblage scattered throughout the Doñana Biological Reserve in order to know if there is a preservation general dynamics, with general patterns that can be applied to the taphonomic study of archaeological sites.

Technological characterization of polychromies on a Balearic medieval stone altarpiece of the 15th century

The objective of this research is to encrease the historical, artistic and material knowledge of the polychrome finishes in a medieval stone altarpiece within the context of the island of mallorca. There are many examples of Gothic art introducing polychrome finishes on stone sculpture, both in the religious and civil sphere in the Iberian Peninsula. In the Balearics, with the Christian conquest, this practice was also extended. The Passio Imaginis Altarpiece (1448-1453), located at San salvador Sanctuary in Felanitx (mallorca) has been studied. The characterization of the polychromies began with an organoleptic examination and photograph of general visible light and flush, assessed by digital image analysis (DIA). DIA allowed to reveal traces of polychromies that had not been detected by nacked eye in order to carry out the proper sampling. The samples were analyzed by optical microscopy (OM); scan electron microscopy (SEM-EDX), and the study of organic binders. The results obtained in the stratigraphic studies revealed the application of a sequence of layers with pigments employed in Iberian Peninsula. Binders detected are egg or animal glue. data indicates that it is most likely an original finish. Colour study contributes through the knowledge of the Passio Imaginis altarpiece and the awareness of its remains, to avoid the interpretation and/or destruction of the pictorial strata present in stone carvings.

Preventive conservation requires identification evaluations, and prioritization of the maintanance and restoration of cultural heritage under different hazards. The degradation of monuments is due to the effects caussed by different agents (earthquakers, floods, weathering, pollutions agents, anthropogenic factors) that produce total or partial losses of architectonic elements or their alterations. The conservation degree of each monument depends on the vunerability, and its index is an indirect function of the level of deterioration, whereas the hazards depend on the localization and its environment conditions, social development and anthropogenic agents. RIVUPH and Art-Risk are Spanish projects based on the analysis of environmental risk in historical cities and models to assess vulnerability and lives of buildings in order to improve the preventive conservation of monuments with similar characteristics. For this purpose, two different approaches have been evaluated: DELPHI method and Fuzzy Logic, where both tools are based on the opinion of experts in the field. The vulnerability analysis of three churches of Seville (Spain) have been studied to assess the monuments conservation degree. Both models (DELPHI and Fuzzy Logic) are able to forecast the necessities of restoration overlapping different scenarios

Research-action on the heritage object : methodologies for approximation and teaching experiences at the final degree project course in the School of Arquitecture of Seville

The course Proyecto Fin de Grado taught at the Degree in Architecture of the University of Seville was implemented in the academic year 2015-2016. It is conceived as a practical subject that follows a dynamic workshop in which students expose weekly the progress of their project with the supervision of eight teachers, one per area of knowledge. This work deals with the results obtained in the academic year 2016-2017 in relation to the intervention projects in Heritage. Working on a Cultural Property inexorably requires the prior generation of exhaustive knowledge about it. From this perspective, the teaching teams of groups 6.01 and 6.07 - of which the authors of this communication are part - understand that this is an essential preliminary stage that will allow the students to base their architectural discourse of intervention on the heritage values detected and the diagnosis of the state of conservation of what exists. This vision also requires assuming that the interest of the exercise is subordinated to the methodological process developed by the student, inasmuch as it should serve them to analyze and evaluate with coherence each one of the project decisions adopted. Despite the complexity of these exercises, it has been detected that, firstly, a high percentage of students choose to develop this type of project; secondly, it requires the participation of the different areas involved in the teaching of the subject; and thirdly, the academic results are generally more satisfactory.

Using BIM and GIS to Research and Teach Architecture [en línea]

This paper describes the use of BIM and GIS in our research of architectural heritage and the experience gained from their implementation from Year 1 to Year 5 in the subjects “Drawing and Machine” and “Drawing 3, Graphical Analysis” taught in the Department of Architectural Graphical Expression of the Seville School of Architecture during the academic years 2014/2015 and 2015/2016. We propose a transition towards a teaching model that integrates analogue and digital with a gradual and coherent approach based on an understanding of architecture itself as a complex system made up of various elements and attributes, both visual and alphanumeric, which allow the “graphical” to transcend the visual and incorporate different types of information

Analysis of materials during the restoration of Tota Pulchra

Tota Pulchra (around 1600), a high quality copy of a painting made by an anonymous artist copying probably an Italian painter Giuseppe Cesari, was recently restored due to its bad conservation state. Before and during its intervention, the artwork was analysed in order to get information about materials and painting technique and help at the restoration process. Several invasive and non-invasive techniques for material identification have been used. Extracted samples were studied with OM, SEM-EDX, FTIR and GC-MS. The results revealed the usual palette for the 16th century, linseed oil binder, chalk based preparation and a complex pigment mixture for priming, as well as several later interventions. Under the OM, also organic fibers from the canvas were identified as flax support for the painting.

Deposits of terrestrial snails : natural or anthropogenic processes?

  • Bernáldez Sánchez, Eloísa
  • García-Viñas, Esteban
In the archaeological sites of the southwestern Iberian Peninsula small dumps of land snails are frequently found. It is likely that these deposits are the traces of human activity. However, it could also be possible that these dumps were produced by a natural process at a period of time when these molluscs were inactive. We will try to explain the origin of these snail deposits by undertaking a statistical analysis to test hypotheses comparing biometric analyses from different groups of snails: those collected by people who usually consume snails in 2009, those found in plants where these molluscs accumulate at the end of the summer of 2009 and those registered in several archaeological sites: “La Gallega” (2,500 BC; Valencina de la Concepción, Seville), “El Carambolo” (ninth-sixth century BC; Camas, Seville), “Cerro de la Albina” (seventh century BC; Puebla del Río, Seville), “C/ San Felipe Neri” (second-third centuries BC; Carmona, Seville), “Hospital de las Cinco Llagas” (twelfth century AC; Seville), “La Almagra” (twelfth century AC; Huelva) and “C/ San Fernando” (twelfth century AC; Seville). The biometric analysis and the biostratinomic observations have provided us a mathematical model to ascertain the origin of deposits of land snails in archaeological sites

Abstract: Human interventions are one of the main drivers of coastal change in many areas, often generating undesired impacts like shoreline retreat. Sandspits are especially sensitive to anthropogenically-induced changes, especially those related to sediment supply. This work presents a case study of Valdelagrana spit in SW Spain, a sandbody where anthropogenic influence has been evident since Roman times. A variety of methods were applied to assess geomorphological and morphodynamic changes in the area at various timescales. Historical interventions involve mainly river course diversion, which caused important changes in sediment supply. More recently, coastal engineering structures and land reclamation deeply modified wave and current patterns in the area, triggering massive coastal erosion. As a consequence of this, the system has evolved from a drift-aligned spit to a swash-aligned barrier. This study provides insights into the consequences of human interventions at similar coastal settings.

This paper is focused on the characterization on roman mural paintings from the archaeological site of Cercadilla (Córdoba, Spain). The mural paintings were located in a thermal complex that belonged to a Roman palace complex from tetrarchy era. White mural paintings with red vertical and horizontal edges decorations were studied. Several tecniques were used to study the mural paintings: such as colorimetry, macrophotography, optical microscopy, scanning electron microscopy, micro X-ray diffraction, X-ray fluorescence. The results allowed us to determine the composition of materials. In addition, the conservation condition of the mural paintings and the weathering forms were studied.
