AS you have seen, the Romans were generally victorious in the wars which they waged against their neighbors. They were so successful, however, only because they were remarkably well trained.
Not very far from the citadel there was a broad plain, bordered on one side by the Tiber. This space had been set aside, from the very beginning, as an exercising ground for the youths of Rome, who were taught to develop their muscles in every way. The young men met there every day, to drill, run races, wrestle, box, and swim in the Tiber.
These daily exercises on the Field of Mars, as this plain was called, soon made them brave, hardy, and expert; and, as a true Roman considered it beneath him to do anything but fight, the king thus had plenty of soldiers at his disposal.
Ancus Martius had greatly encouraged the young men in all these athletic exercises, and often went out to watch them as they went through their daily drill. He also took great interest in the army, and divided the soldiers into regiments, or legions as they were called in Rome.
As the city was on a river, about fifteen miles from the sea, Ancus thought it would be a very good thing to have a seaport connected with it; so he built a harbor at Ostia, a town at the mouth of the Tiber. Between the city and the port there was a long, straight road, which was built with the greatest care, and made so solidly that it is still in use to-day.
To last so long, a road had to be made in a different way from those which are built to-day. The Romans used to dig a deep trench, as long and as wide as the road they intended to make. Then the trench was nearly filled with stones of different sizes, packed tightly together. On top of this thick layer they laid great blocks of stone, forming a strong and even pavement. A road like this, with a solid bed several feet deep, could not be washed out by the spring rains, but was smooth and hard in all seasons.
Little by little the Romans built many other roads, which ran out of Rome in all directions. From this arose the saying, which is still very popular in Europe, and which you will often hear, "All roads lead to Rome."
The most famous of all the Roman roads was the Appian Way, leading from Rome southeast to Brundusium, a distance of three hundred miles. This road, although built about two thousand years ago, is still in good condition, showing how careful the Romans were in their work.
