En los últimos años el estudio del complejo subterráneo existente por debajo de la ciudad ha desarrollado una prometedora línea de investigación para la comprensión de los acontecimientos que llevaron al auge de la cultura teotihuacana. La existencia de cuevas en el valle y su importancia en la cosmovisión indígena es conocida desde antiguo. En este artículo se analiza el papel que pudieron jugar las cuevas ceremoniales del sureste de la Pirámide del Sol durante el período de formación del estado teotihuacano hasta el cierre de las mismas en el Tlamimilolpa tardío (350 dC).

En un artículo anterior, presentamos algunos de los datos obtenidos durante los trabajos de investigación realizados en las cuevas situadas al sudeste de la Pirámide del Sol (lámina 1, cuadrante N3E2, Millon 1973). Durante los meses de marzo a agosto de 1993 se realizaron excavaciones en esta área, que permitieron definir un complejo subterráneo ceremonial compuesto por tres cuevas integradas dentro de un patio hundido. En este artículo se exponen los datos arqueológicos de la tercera cueva que ha proporcionado materiales pertenecientes a fases de ocupación posteotihuacanas (900/1000-1200 dC) y su relación con otras investigaciones realizadas en la zona arqueológica en los últimos años.

This study examines the correlation between buccal dental microwear and stable isotopes. The buccal surface of post-canine teeth casts from El Collado, the largest Mesolithic site in Spain, were examined under Scanning Electron Microscope; photomicrographs were taken from the middle third of the buccal surface with magnification 100X. Only six individuals passed the criteria for buccal dental microwear analysis. The photomicrographs were treated by adobe Photoshop 8.01 to cover an area 0.56 mm² of middle third of buccal surface, the output photomicrographs were digitized using Sigmascan Pro 5 by SPSS. Then the correlation between buccal microwear pattern and stable isotopes of the same individuals, of the previous study of Guixe et al., 2006, was examined using a Pearson test. Statistical analysis revealed that there is no significant correlation between stable isotopes and buccal dental microwear of the people of the Mesolithic site of El Collado. The historical and archaeological documentation suggest that the Mesolithic people tended to consume marine food. Fish-drying techniques were used during the Mesolithic period which allowed the introduction of dust and sand to the fish. These abrasive particles affected the buccal dental microwear pattern, so that no correlation between the isotopes and microwear may be expected. This also suggests that the buccal dental microwear pattern exceeds dietary reconstruction to reconstruct food processing techniques.

Toda obra arquitectónica necesita de una proyección previa que implique la definición y justificación de sus formas y proporciones, proyección que, a menudo, viene modificada por la realidad ya existente o, en casos de periodos constructivos largos por cambios de opinión, de finalidad o, incluso de promotor. Es el caso del Concilium Provinciae Hispaniae Citerioris de Tarraco, un gran complejo monumental de más de 12 hectáreas de extensión, que necesitó un periodo de tiempo de construcción de entre 70 a 75 años. Los restos arqueológicos conservados permiten la identificación de dos proyectos arquitectónicos sobrepuestos que implican un profundo cambio de proyecto durante el proceso constructivo.

Una revisión de los datos arqueológicos actualmente conocidos en relación a la antigua Tarraco nos permite plantear nuevas hipótesis de trabajo, que apuntan a la posibilidad de que la primera fortificación romana corresponda al período de la Segunda Guerra Púnica, debiéndose a los hermanos Escipiones o a Escipión el Africano. Asimismo, creemos que existen suficientes datos para plantear una posible implantación urbanística ex novo situada entre el praesidium militar y el oppidum indígena, en el tercer cuarto del siglo II a. de J.C., que podría haber sido fundada por Escipión Emiliano. Por ello, la frase pliniana Tarraco Scipionum opus alcanza nuevas dimensiones no valoradas hasta la fecha.

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.

El artículo presenta el estudio de un área arquitectónicamente compleja, integrada dentro del denominado Foro Provincial de Tarraco . El análisis de la estratigrafía arquitectónica y de los procesos de construcción, ha representado un instrumento fundamental para la interpretación de un área caracterizada por una compleja evolución urbanística, poniendo en evidencia el desarrollo del proyecto constructivo de una obra de gran envergadura como la del Foro Provincial. Desafortunadamente, la ausencia de datos procedentes de las excavaciones arqueológicas, ha limitado la definición de una cronología absoluta exacta. El proceso de monumentalización de la cima de la colina tarraconense iniciado, según las fuentes históricas y numismáticas, en época julio-claudia, culminó en época Flavia con la finalización del complejo monumental distribuido en tres terrazas. El sector que se examina, situado junto al circo, se encuadra dentro de un sistema de substructiones que a menudo caracterizan los conjuntos forense y sacro organizados en terrazas.

This paper presents a brief description of the archaeological research in the territory and in the city of Tarraco, the ancient capital of provincia Hispania Tarraconensis and one of the main centres for the spread of Hispanic Christianity. Althoug Tarraco was the last capital under imperial control and the firs Hispanic metropolitan see, the city had only a secondary role by comparison with other Hispanic cities during late antiquity. This evolution shaped the development of Tarraco during the 7th century, but archaeologists identify an important architectural vitality still in the 6th century at the same time as other episcopal cities were evolving. During this period, the final Christianization of the symbolic spaces of ancient paganism took place, establishing the ideological basis of medieval urbanism that is still preserved today. The paper also interprets the sites through raising key questions as well as describing rural settlements, where archaeological knowledge is not so far advanced, due in part to the difficult nature of archaeological research, and in part to the need to study new construcitve models, as well as to the systematic collection of the relevant material culture.

The city of Tarragona houses an important architectural heritage mainly from its past as ‘Tarraco’, capital of the Roman province of Hispania Citerior, but also from its medieval and late 19th century history. The archaeological ensemble of Tarraco was inscribed as a UNESCO World Heritage Site in 2000, but although many efforts have been devoted by archaeologists and historians to unveil and understand the history and aspect of the Roman city, many aspects remain unknown. This is largely caused by the absence of a coherent body of historiographical material, which is todays cattered across several institutions and, specially, the lack of precise and useful graphical representations of the remains and of the existing city that allows in-depth analysis and interpretations of future findings. In recent years, researchers from the Catalan Institute of Classical Archaeology (ICAC) and the Architecture School of the URV (ETSA) have teamed up to produce comprehensive, detailed graphic materials, including a new set of plans and sections of the old city, of the grandiose areas of representation of the Provincial capital, and of the hidden structures beneath the city’s surface. These have been executed with the latest technologies (fotogrammetry, laser scanning) but also with traditional methods (measurement, topography), on t op of a mixture of existing materials (hand-drafted cartography from municipal master plans) and of historical and archaeological documentation.
