A certain Andriscus, who was a native of Atramyttium and resembled Perseus in appearance, caused a wide area of Macedonia to revolt by pretending to be his son and calling himself Philip. First he went to Macedonia and tried to upheave the country, but as no one would yield him allegiance he took his way to Demetrius in Syria to obtain from him the aid which relationship might afford. Demetrius arrested him and sent him to Rome, where he met with general contempt, both because he stood convicted of not being the son of Perseus and because he had no other qualities that were worthy of attention. On being released he gathered a band of revolutionists, drew after him a number of cities, and finally, assuming the kingly garb and mustering an army, he reached Thrace. There he added to his army numbers of the independent lands as well as numbers of princes who disliked the Romans, invaded Macedonia (which he occupied), and setting out for Thessaly made not a little of that territory his own. The Romans at first scorned Andriscus and then they sent Scipio Nasica to effect some peaceful settlement in those parts. On reaching Greece and ascertaining what had occurred he despatched a letter to the Romans explaining the case; then after collecting troops from allies there he gave attention to the business in hand and advanced as far as Macedonia. The people of Rome when informed of the doings of Andriscus sent an army and Publius Juventius, a praetor. Juventius had just reached the vicinity of Macedonia, when Andriscus gave battle, killed the praetor, and would have annihilated his entire force but for its withdrawal by night. Next he invaded Thessaly, damaged a very great extent of it, and ranged Thracian interests on his side. Consequently the people of Rome once more despatched a praetor, Quintus Caecilius Metellus, with a strong body of troops: he proceeded to Macedonia and enjoyed the assistance of the fleet of Attalus. The fleet inspired Andriscus with some alarm for the coast districts so that he did not venture to advance farther but moved up to a point slightly beyond Pydna. There he had the best of it in a cavalry encounter but out of fear of the infantry turned back. His elation was such that he divided his army into two sections, and with one remained on the watch where he was, while he sent the other to ravage Thessaly. Metellus in derision of the forces confronting him joined battle, and by overpowering those with whom he first came into conflict he got control of the remainder with greater ease; for they made terms with him readily, inasmuch as they had erred. Andriscus fled to Thrace and after assembling a body of fighters gave battle to Metellus as the latter was advancing on his track. His vanguard, however, was routed first; then his contingent of allies was scattered; and Andriscus himself was betrayed by Byzes, a Thracian prince, and executed.
