espanolPresentamos una sintesis del contexto historico y arqueologico de Graccurris, primera fundacion romana de epoca republicana en el valle del Ebro. Nos centramos en el estudio de pavimentos, pinturas y estucos del sector C del yacimiento, prestando especial atencion a los encontrados en la habitacion 2 de la Casa 4, pavimentada con opus signinum, conservado in situ, y decoradas sus paredes con pinturas, halladas en estado fragmentario. El pavimento y el conjunto 2 corresponden a una primera fase decorativa, del siglo I d.C., relacionada con la remodelacion de la ciudad en dicha epoca, mientras que la cronologia del conjunto pictorico 1 nos lleva a principios del siglo II d.C., fecha que coincide con la reforma de la domus. Las primitivas pinturas, conservadas parcialmente, presentan un esquema sencillo: zocalo gris moteado y paneles rojos bordeados de bandas negras en la zona media. La decoracion de la segunda fase es mas compleja: zocalo con imitaciones marmoreas, zona media articulada en una sucesion de columnas y paneles que emulan marmol serpentino y, finalmente, en la zona superior se dispone un sistema de relacion continua. Marmoles y columnas forman parte de la corriente pictorica en boga en el valle del Ebro en el siglo II d.C. EnglishWe present a synthesis of the historical and archaeological context of Graccurris, the first Roman foundation of the republican era in the Ebro Valley. We focus on the study of pavements, paintings and stuccoes in sector C of the site, paying special attention to those found in room 2 of House 4, paved with opus signinum, preserved in situ, and having its walls deco-rated with paintings, being found in fragmentary state. The pavement and the set 2 correspond to the? first decorative phase, from the 1st century AD, related to the remodeling of the city at that time, while the chronology of the pictorial set 1 takes us to the beginning of the 2nd century AD, a date that coincides with the domus reform. The primitive paintings, partially pre-served, have a simple scheme: mottled gray plinth and red panels lined with black bands in the middle area. The decoration of the second phase is more complex: plinth with marble imitations, middle area articulated in a succession of columns and panels that emulate serpentine marble and, finally, in the upper area there is a continuous relationship system. Marbles and columns are part of the pictorial trend in vogue in the Ebro valley in the second century A.D.
