Recent Archaeological landscape studies in the Valley of Alcoi (Eastern Iberia) have detected important settlement changes during the 1st c. BC related to Roman territorial organization. Rural settlement of previous Iberian Iron Age was confined to areas close to fortified oppida due to defensive strategies, but Roman pacification and dominion of the region created a context of political stability that allowed an increase of rural sites, with significant occupation of previously empty areas. The resulting rural landscape was composed by small farms connected to small plots of intensive uses, with manuring and terracing as agrarian strategies. This spatial organization characterized the later Roman Imperial Landscape. The aim of this communication is to present the archaeological data that permits the characterization of this landscape of intensive farmers. We present an analytical strategy combining spatial analysis, microstratigraphic analysis by means of soil micromorphology and physical-chemical analyses of bulk soil samples, as well as archaeobotanical analyses including palynology, phytoliths and other calcitic microfossils. This high-resolution, multiscalar, and multianalytical approach pursues to characterize these archaeological contexts to singularize these intensive agricultural practices. The creation of this peasant landscape is related to specifics models of economic and social organization in the Roman period.

[EN] This paper presents a multi-proxy proposal based on crossreferencing different teaching strategies such as traditional class, flipped teaching and the case method in the subject of Ancient Universal Prehistory (second year) in the Degree in History at the University of Valencia whitin the framework of the METARQ Teaching Innovation Project. The learning of theoretical and practical content has been reinforced in a single evaluable activity for the practical part of the course, which consisted of different stages. The results show that 58% of the students participating in the proposed activities, improved their grades in the theoretical-practical contents of the subject. It is, therefore, a proposal with a very positive impact on student learning and performance., [ES] En este trabajo se presenta una propuesta multi-proxy basada en el empleo cruzado de distintas estrategias docentes como la clase tradicional, la clase inversa y el método del caso en la asignatura de Prehistoria Universal Antigua (2º curso-1er cuatrimestre) en el Grado de Historia de la Universitat de València, en el marco del Proyecto de Innovación Docente METARQ. El aprendizaje de contenidos teórico- prácticos se ha reforzado en un única actividad evaluable para la parte práctica de la asignatura y que constaba de diferentes etapas. Los resultados muestran que el desarrollo de actividades evaluables que revisan todos los contenidos teórico-prácticos puede tener un impacto muy positivo sobre el aprendizaje y el rendimiento del estudiantado.

Este trabajo tiene por objetivo evaluar las posibilidades que ofrece el análisis de imagen efectuado sobre soporte fotográfico obtenido con smartphone en la caracterización colorimétrica de los pigmentos utilizados en el arte rupestre prehistórico. Con este fin, se procedió a la elaboración experimental de pigmentos minerales, siguiendo distintas recetas basadas en datos arqueológicos y etnológicos, y se aplicaron sobre una superficie de roca carbonatada similar al soporte donde se localizan las pinturas rupestres holocenas del arco mediterráneo. Cada trazo elaborado con las distintas recetas fue fotografiado con un smartphone en ambiente controlado y analizado con un espectrómetro de fluorescencia de rayos X portátil para evaluar la relación entre los niveles elementales de los pigmentos y los parametros de color obtenidos por análisis de imagen.

This paper presents the study of various Roman materials used in the construction of the Maritime Theatre, one of the main buildings in the Hadrian’s Villa complex, a designated UNESCO World Heritage Site located in Tivoli (Rome, Italy), dating to the first half of the II century A.D. The plaster layers (arriccio and intonachino) and overlying original Roman paintings that form the concave wall of the portico as well as some bedding mortars of the pyramidal stone elements (i.e. cubilia) of the circular masonry have been studied in particular. In addition, the acid volcanic rocks of the cubilia have been investigated, aiming to understand their state of alteration and geological origin. By mineralogical-petrographic microscopy (OM), diffractometry (XRPD), Raman spectroscopy, Point Load Tests (PLT), helium pycnometry, and particle size analysis, the composition and granulometric distribution of the aggregate, type and characteristics of the binder, and various physical-mechanical properties (density, porosity, water absorption, imbibition and saturation indices, mechanical resistance) of mortars and stones were defined. In addition, through digital image analysis of thin sections, the binder/aggregate ratio and some geometric characteristics of the aggregates (e.g. circularity) were determined. The research aims to improve the knowledge of the constructive technologies of the Maritime Theatre through the analysis of its materials.

In this work, a fast method for obtaining a quantitative elemental mapping of highly inhomogeneous samples by µ-LIBS maps is proposed. The method, transportable and cheap, allows the analysis of large maps through the use of a Self-Organizing Map clustering method coupled to Calibration-Free LIBS for quantification of cluster prototypes. The method proposed has been verified on heterogeneous materials such historical lime mortars but it can be easily applied to a larger class of inhomogeneous materials for very different applications (modern building materials, biological samples, industrial materials, etc.).
