Abstract
This paper focuses on the topography of communication and investigates the semiotic value of one particular site, where highly significant political actions took place. The different strategies of communication at the time of the late Roman Republic are analysed by matching the memory of ancient sources to the investigation of the cultural value of the domus rostrata in Rome. The house is taken as a legitimising element in the ideology of Pompeius, and one which was also appropriated by the subsequent owners of the house.
