Rome itself was changed by the increased wealth of these times. The streets were made wider; temples were multiplied; and aqueducts were built to bring water from distant sources; the same Appius who constructed the great road which now bears his name, having built the first, which, however, disappeared long ago. Another, forty-three miles in length, was paid for out of the spoils of the war with Pyrrhus, and portions of it still remain. With the increase of wealth and luxury came also improvement in language and in its use, and in the year 254, studies in law were formally begun in a school established for the purpose. [Figure: ACTORS MASKS.] The Romans had conquered Italy and Carthage, and the next step was to make them masters of the East. Philip V., King of Macedon, was, as we have seen, one of the most eminent of monarchs of that country. His treaty with Hannibal after the battle of Cannæ, involved him in war with the Romans, which continued, with intermissions, until Scipio was about to go over into Africa. Then the Romans were glad to make peace, though no considerable results followed the struggle, and it had indeed been pursued with little vigor for much of the time. By the year 200, Philip had been able to establish himself in Greece, and the Romans were somewhat rested from the war with Carthage. The peace of 205 had been considered but a cessation of hostilities, and both people were therefore ready for a new war. There were pretexts enough. Philip had made an alliance with Antiochus the Great, of Syria, against Ptolemy Epiphanes, of Egypt, who applied to Rome for assistance; and he had sent aid to soldiers to help Hannibal, who had fought at the battle of Zama. Besides this he had attempted to establish his supremacy in the Ægean Sea at the expense of the people of Rhodes, allies of Rome, who were assisted by Attalus, King of Pergamus, likewise in league with Rome.
