The Roman Government before the Period of the Gracchi
For a whole generation after the battle of Pydna the Roman state
enjoyed a profound calm, scarcely varied by a ripple here and there
on the surface. Its dominion extended over the three continents;
the lustre of the Roman power and the glory of the Roman name were
constantly on the increase; all eyes rested on Italy, all talents and
all riches flowed thither; it seemed as if a golden age of peaceful
prosperity and intellectual enjoyment of life could not but there
begin.
The Orientals of this period told each other with astonishment
of the mighty republic of the west, "which subdued kingdoms far and
near, and whoever heard its name trembled; but it kept good faith
with its friends and clients. Such was the glory of the Romans, and
yet no one usurped the crown and no one paraded in purple dress; but
they obeyed whomsoever from year to year they made their master, and
there was among them neither envy nor discord."
