SALDVIE n.º 9 2009 pp. 97-118 The Early Iron Age upper and middle Ebro group. Cabezo Morrudo (Rodén, Zaragoza) within the frame of the “Eastern middle Ebro sub-group” El Grupo del Hierro del Alto y Medio Ebro. Cabezo Morrudo (Rodén, Zaragoza) dentro del marco del “Subgrupo del Ebro Medio Occidental” Víctor E. M. Maturén* Abstract The research of domestic assemblages constitutes nowadays one of the best tools in order to study the ethnicity of protohistoric peoples. Taking into account that it is very probable that Early Iron Age middle Ebro peasant com- munities made the largest part of its hand-built wares within the household and that a generalized exogamy took place within more or less established marital areas, this research tries to identify territories connected by a series of privileged ties, as for example the “Eastern middle Ebro sub-group” between the Huerva river and the Martín river. Cabezo Morrudo (Rodén, Zaragoza) Phase II would be completely inserted in this last area, showing an inter- esting destruction layer that should be contextualized within the frame of the 7th and 6th cal BC Ebro valley destruction horizon. Keywords: Ebro valley, Cabezo Morrudo (Rodén, Zaragoza), Early Iron Age, exogamy, domestic domain, hand- made pottery. Resumen El estudio de la cultura material producida dentro del ámbito doméstico constituye, en la actualidad, una de las mejores herramientas con las que cuentan los investigadores para estudiar a los pueblos protohistóricos. Teniendo en cuenta que es muy probable que las comunidades campesinas del Valle Medio del Ebro produjeran la mayor parte de su cerámica manufacturada dentro del ámbito doméstico y que existiera, así mismo, una exogamia gene- ralizada dentro de áreas matrimoniales más o menos establecidas, el presente estudio intenta identificar territo- rios unidos por vínculos privilegiados, como por ejemplo el denominado provisionalmente “Subgrupo del Ebro medio oriental”, entre el río Huerva y el río Martín. La Fase II de Cabezo Morrudo (Rodén, Zaragoza) se encon- traría plenamente integrada dentro de este ámbito geográfico, presentando un interesante nivel de destrucción que debería contextualizarse dentro del marco del horizonte de destrucción del Valle del Ebro en los siglos VII y VI cal A.C. Palabras clave: Valle del Ebro, Cabezo Morrudo (Rodén, Zaragoza), Primera edad del hierro, exogamia, ámbito doméstico, cerámica manufacturada. * DEA in Prehistory, University of Zaragoza.
