A spatial data warehouse to predict lithic sources of tombs from South of Portugal: mixing geochemistry, petrology, cartography and archaeology in spatial analysis

MEGAGEO - Moving megaliths in the Neolithic is a project that intends to find the provenience of lithic materials in the construction of tombs. A multidisciplinary approach is carried out, with researchers from several of the knowledge fields involved. This work presents a spatial data warehouse specially developed for this project that comprises information from national archaeological databases, geographic and geological information and new geochemical and petrographic data obtained during the project. The use of the spatial data warehouse proved to be essential in the data analysis phase of the project. The Redondo Area is presented as a case study for the application of the spatial data warehouse to analyze the relations between geochemistry, geology and the tombs in this area.

Desmitificaciones, historia y símbolos: los héroes impuros (Rosibel Morera)

In this article I analize the novel Los héroes impuros by the Costa Rican authoress Rosibel Morera. The analytical categories used include, from the elimination of absolute historical facts, all the way to the notion of eternal return (Mircea Eliade), processes of idolization, and the various symbols appearing on the text. Examination of these categories shows the characters´ duality because of their universality, and also the worldview and the conception of literature held by Morera.
