The progress of nations was much slower in ancient days than now, and these two rival empires continued their gradual growth and extension, each on its own side of the great sea which divided them, for five hundred years, before they came into collision. At last, however, the collision came. It originated in the following way:
By looking at the map of Italy, the reader will see that the island of Sicily is separated from the main land by a narrow strait called the Strait of Messina. This strait derives its name from the town of Messina, which is situated upon it, on the Sicilian side. Opposite Messina, on the Italian side, there was a town named Rhegium. Now it happened that both these towns had been taken possession of by lawless bodies of soldiery. The Romans came and delivered Rhegium, and punished the soldiers who had seized it very severely. The Sicilian authorities advanced to the deliverance of Messina. The troops there, finding themselves thus threatened, sent to the Romans to say that if they, the Romans, would come and protect them, they would deliver Messina into their hands.
The question, what answer to give to this application, was brought before the Roman senate, and caused them great perplexity. It seemed very inconsistent to take sides with the rebels of Messina, when they had punished so severely those of Rhegium. Still the Romans had been, for a long time, becoming very jealous of the growth and extension of the Carthaginian power. Here was an opportunity of meeting and resisting it. The Sicilian authorities were about calling for direct aid from Carthage to recover the city, and the affair would probably result in establishing a large body of Carthaginian troops within sight of the Italian shore, and at a point where it would be easy for them to make hostile incursions into the Roman territories. In a word, it was a case of what is called political necessity; that is to say, a case in which the interests of one of the parties in a contest were so strong that all considerations of justice, consistency, and honor are to be sacrificed to the promotion of them. Instances of this kind of political necessity occur very frequently in the management of public affairs in all ages of the world.
