RUBICON, a small stream of ancient Italy, which flowed into the Adriatic between Ariminum and Caesena, and formed the boundary between Italy and the province of Cisalpine Gaul.
I was like one who never casts a look behind, who hesitates before some Rubicon to be crossed, but having touched the farther bank sees no more the shore he has just left."
By September he had crossed the Rubicon, Henry Newman (his rector at Shepton Beauchamp and Sparkford) accompanying him on a tour in Carnarvonshire.
The historic importance of this event gave rise to the phrase "crossing the Rubicon" for a step which definitely commits a person to a given course of action.
It was adopted by Augustus as the boundary of Gallia Cispadana; the far-famed Rubicon was a trifling stream a few miles farther north, now called Fiumicino.
As such it was assigned to Julius Caesar, together with Transalpine Gaul, and it was not till he crossed the Rubicon that he entered Italy in the strict sense of the term.

Romanization had, however, progressed considerably, the foundation of colonies and the construction of roads had gone on during the 2nd century, and the whole district as far as the Padus was given the Roman franchise in 89 B.C., while the Transpadanes received Latin rights, and were fully enfranchised forty years later.
The Ronco (Bedesis) and Montone (Utis), which flow into the sea together east of Ravenna, were also tributaries of the Po; and the Savio (Sapis) and the Rubicon seem to be the only streams from this side of the Tuscan Apennines that ran directly into the sea in Roman days.
