The purpose of this work is to evaluate the possible impact of the so-called “crisis of the 3rd century” in the area between Tarraco (Tarragona) and Saguntum (Sagunt), currently corresponding to the southern limit of Catalonia and the north of Valencia, which during the Roman era made up the southernmost part of the conventus Tarraconensis. The processes of change experienced in rural settlements and cities between the Severan dynasty and the beginning of the tetrarchy are analyzed, and the importance of the city-country relationship is examined to explain these changes. The extent of the Frankish invasion during of the Gallic period, initially substantiated by sources and now by archaeological evidence, is discussed. The study of coin hoards (treasures and deposits) from the second half of the 3rd century, found in abundance in this area, is a very interesting aspect of this topic. In addition, a quantitative approach is used to study the population changes experienced as a result of the rural settlement of this area during the 3rd century, between the High and the Low Empires.

The ancient temple dedicated to the Roman Emperor Augustus on the hilltop of Tarraco (today’s Tarragona), was the main element of the sacred precinct of the Imperial cult. It was a two hectare square, bordered by a portico with an attic decorated with a sequence of clypeus (i.e. monumental shields) made with marble plates from the Luni-Carrara’s quarries. This contribution presents the results of the analysis of a three-dimensional photogrammetric survey of one of these clipeus, partially restored and exhibited at the National Archaeological Museum of Tarragona. The perimeter ring was bounded by a sequence of meanders inscribed in a polygon of 11 sides, a hendecagon. Moreover, a closer geometric analysis suggests that the relationship between the outer meander rim and the oval pearl ring that delimited the divinity of Jupiter Ammon can be accurately determined by the diagonals of an octagon inscribed in the perimeter of the clypeus. This double evidence suggests a combined layout, in the same design, of an octagon and a hendecagon. Hypothetically, this could be achieved by combining the octagon with the approximation to Pi used in antiquity: 22/7 of the circle’s diameter. This method allows the drawing of a hendecagon with a clearly higher precision than with other ancient methods. Even the modelling of the motifs that separate the different decorative stripes corroborates the geometric scheme that we propose.

One of the founders of numismatics in Modern Age was the archbishop of Tarragona and renowned jurist Antonio Agustín. He was educated during the mid-sixteenth century mainly in Italy, particularly in Bologna and Padua. His role in the development of antiquarian studies – and interest in collecting – ran parallel to the development of numismatics in the Cinquecento. His interest in realia , i.e., the materials and documents perceived as primary evidence of history understood in a global sense, make him a pioneer in setting the trends and methodologies which would be later employed by Bernard de Montfaucon. The period Antonio Agustín spent in Bologna, at the Reale Collegio di Spagna, between 1539 and 1544, afforded him the opportunity to enter a very cultivated circle where the admiration and study of the Antique was well established since the mid-fifteenth century. The cultural effervescence taking place in Bologna was encouraged by the court of Giovanni II Bentivoglio and the University alike. Artists also contributed to the development of antiquarian knowledge, and the painter Amico Aspertini (ca. 1475-1552) exemplifies this. It is clear that Antonio Agustín certainly benefited from the scholarly environment in Bologna during the first half of the Cinquecento, which had been firmly anchored since the fertile Quattrocento. Although the documentary evidence is scarce, and it is difficult to pinpoint the details, it is undeniable that Antonio Agustín was heavily influenced by his Bolognese experience.

This article presents a panoramic view of the development of the so-called serliana or Serlian motif throughout the Italian Renaissance, focusing on the most relevant examples in the architecture of that period. The use of this motif during the Early Renaissance was pioneered by Filippo Brunelleschi in religious buildings. As its employment become widespread in a range of different settings, architects frequently incorporated local building traditions. It was only during the last twenty years of the Quattrocento that Giuliano da Sangallo and Leonardo da Vinci adopted the Serlian arch in residential architecture designed for the ruling elites. Thanks to Bramante and other artists such as Raphael, Baldassare Peruzzi, Antonio da Sangallo the Younger and Giulio Romano, the motif was extraordinarily popular during the High Renaissance period. Ever-increasingly complex and monumental compositions eased the adaptation of the serliana to both exterior and interior spaces, and in works such as the design by Galeazzo Alessi in Genoa, the imperial connotation of the motif is clear. This process illustrates the progressive transfer from the religious to the courtly sphere, and, at the same time, the permeability between the sacred and the profane. During the sixteenth century, Spain too was at the European avant-garde, due to its contacts with Italy and the latest fashions, such as the employment of the serliana in residential architecture, were followed in the fortified palace at La Calahorra, the Vich palace in Valencia, or the palace of Charles V in Granada, as part of a complex iconography of power. Throughout the sixteenth century, the serliana featured in that specifically-Spanish typology, the monumental altarpiece or retablo, as well as in monumental tombs. Italy was certainly the leading force in the process and had an indisputable influence on Spanish art, but the latter would develop its own original solutions in the sixteenth century, which matched the innovative character of Italian creations.

Les darreres recerques dutes a terme en el Projecte Ager Tarraconensis (PAT) han permès augmentar considerablement els coneixements existents sobre l’antiguitat tardana al territorium de Tarraco, tema que ja havíem estudiat parcialment en la nostra tesi doctoral (1992), que inclou també altres àrees del Camp de Tarragona no incloses al PAT. D’altra banda, en els darrers anys hem tingut també ocasió d’estudiar parcialment el poblament antic a la zona de les terres de l’Ebre i al nord del País Valencià, molt especialment a les comarques de l’Alt Palància i la Plana de Castelló. El conjunt d’aquests estudis ens permet plantejar una visió general sobre el poblament tardoantic en una zona determinada que correspon a la part costanera meridional de l’antiga provincia Tarraconensis, amb els límits i la denominació que rep a partir de la divisió de Dioclecià. L’estudi comparatiu del poblament tardoantic d’aquestes àrees permet contrastar, a més de punts en comú, també algunes diferències, tant en el diferent grau de pervivència dels hàbitats després de la crisi del segle III com en l’aparició de nous tipus d’hàbitats (poblats en altura) que no apareixen en totes les àrees, sinó només en les més meridionals. S’aborda també la problemàtica de l’existència d’unes poques vil·les luxoses durant el segle IV (especialment la controvertida de Centcelles), en contrast amb altres hàbitats més modestos, així com el pas de la vil·la a un altre tipus de poblament dispers.

En los últimos años, se han publicado diversos estudios que han permitido tener un buen conocimiento sobre las importaciones (terra sigillata, ánforas, lucern as) en la costa de la antigua Hispania Tarraconensis en época romana tardía. Este conocimiento, concerniente a los contextos urbanos (las ciudades antiguas de Barcino, Tarraco y otras) y los establecimientos rurales, permite determinar las tendencias de las importaciones y la economía en esta área entre los siglos IV y finales del VI e inicios del VII d.C. El aumento de datos necesita una interpretación, orientada hacia la determinación de las tendencias del comercio y las importaciones, y la relación económica entre la ciudad y el campo en la actual Cataluña en la Antigüedad Tardía. Con esta contribución, esperamos poder colaborar en la elaboración de un trabajo interpretativo de síntesis sobre estos aspectos.

Dentro del Proyecto Ager Tarraconensis, se han estudiado en el Camp de Tarragona 19 yacimientos con indicios de instalaciones de producción de aceite o vino, que se centran especialmente entre los siglos I a.C. y II d.C. También se han estudiado 22 yacimientos con indicios de alfarería, en siete de los cuales se conoce la producción de ánforas vinarias. El hallazgo de diversas marcas de alfarero dónde identificamos el nombre de M. Clodius Martialis apunta hacia una rica familia de la elite de Tarraco, con la que se han relacionado cuatro yacimientos y quizás un quinto. Entre la época de Augusto y el siglo III, el vino se confirma como el producto principal de una agricultura desarrollada dentro del sistema de la villa, enfocada al mercado de ultramar. El aceite se debió producir para el consumo local. Esta región no volvió a potenciar la producción de vino a nivel de gran negocio de ámbito internacional hasta el siglo XVIII, con el cual se establece una comparación.

L"estudi ha estat realitzat sobre restes dentals recuperades al jaciment de Forat de Conqueta. La majoria de les dents s"han trobat aïllades, fora del suport ossi, la qual cosa n"ha dificultat la identificació i l"estudi. Entre els objectius de l"estudi paleodontològic, volem destacar la determinació d"un nombre mínim i màxim d"individus a partir de les restes. L"estudi ha estat molt limitat a causa de la tipologia funerària (enterrament col·lectiu en cova) i del ritual d"enterrament (cremació parcial). El resultats provisionals assenyalen que el nombre mínim d"individus representats per la mostra estudiada és de 41 i que, d"aquests, fins a sis individus podrien pertànyer a un grup d"edat infantil o juvenil

Ceramic vessels and milling stones are important components of the archaeological record in several Nuraghi from the Pranemuru Plateau (Sardinia). To obtain information on the possible uses of the milling stones and the content vessels is of great interest to understand the economical activities carried out in these sites by these populations. One of the approaches to obtain information on the plant uses was the phytolith analyses of the sediment adhered both to the surface of the milling stones and to the surface of the vessel content. In total we analyzed eleven archaeological samples and two control samples collected from five different Nuraghi in the Pranemuru Plateau (Nuoro Province, Sardinia). The Nuraghi were located in an area of 10 km radius from nuraghe Arrubiu and were chronologically ascribed to the Bronze Age and one site -Pranu Illixi- to the Iron Age.
