The colleague of M. Fulvius Nobilior was Cn. Manlius Vulso, who had received Asia as his province, that he might conclude the peace which his predecessor, Scipio Asiaticus, had made with Antiochus, and arrange the affairs of Asia. But Manlius was not content with the subordinate part allotted to him; and being anxious for booty as much as for glory, he attacked the Galatians in Asia Minor, without waiting for any instructions from the Senate, and in direct opposition to the ten commissioners who had been sent to arrange conjointly with him the affairs of Asia. This was the first instance in which a Roman general had made war without the authority of the Senate or the People; a dangerous precedent, which was afterward only too faithfully followed. The Galatians were, as has been already said, a body of Gauls, who, after laying waste a great part of Asia Minor, had settled in the north of Phrygia. They had fought in the army of Antiochus at Magnesia, and this supplied Manlius with a pretext for marching against them. He defeated them in two battles, and compelled them to sue for peace. The campaign greatly enriched Manlius and his legions, as the Gauls had accumulated enormous wealth by their many conquests in Asia. Manlius remained another year (B.C. 188) in the East as Proconsul, and, in conjunction with the ten commissioners, formally concluded the peace with Antiochus, and settled the affairs of Asia. Eumenes, the king of Pergamus, received Mysia, Lydia, and part of Caria. The Rhodians obtained the remaining portion of Caria, together with Lycia and Pisidia. Manlius returned to Rome in B.C. 187, and his triumph, like that of Scipio Asiaticus, was most magnificent. But his soldiers, like that of Scipio, introduced into the city the luxuries of the East. These campaigns, as we shall presently see, exercised a most injurious influence upon the character of the Roman nobles and people, teaching them to love war for the sake of acquiring wealth, and prompting them to acts of robbery and rapine.
