With the revival during the fifteenth century of interest in the topography of ancient Roman Italy, the matter of identifying the Rubicon in the contemporary landscape became a topic of debate among Renaissance humanists. To support the claim of the Pisciatello, a spurious inscription forbidding the passage of an army in the name of the Roman people and Senate, the so-called "Sanctio", was placed by a bridge on that river. The Quattrocento humanist Flavio Biondo was deceived by it; the actual inscription is conserved in the Museo Archeologico, Cesena. As the centuries went by, several rivers of the Adriatic coast between Ravenna and Rimini have at times been said to correspond to the ancient Rubicon.
