3. Q.MarciusPhilippus, L. F. Q. N., son of No. 2, was praetor B. C. 188, and obtained Sicily as his province. Two years afterwards, B. C. 186, he was consul with Sp. Postunmius Albinus. These consuls were commanded by the senate to conduct the celebrated inquiry into the worship of Bacchus, which had been secretly introduced into Italy and been the occasion of much immorality and profanity. We accordingly find the name of Philippus in the senatus consultum de Bacchanalibus, which has come down to us. After Philippus had finished his share in these investigations, he set out for Liguria, where he and his colleague had to carry on war. Here, however, he was unsuccessful. In the country of the Apuani, he was surprised by the enemy in a narrow pass, and lost
These services did not go unrewarded, and in B. C. 169 Philippus was a second time chosen consul, and had as his colleague Cn. Servilius Caepio. The conduct of the Macedonian war fell to Philippus. This war had already lasted two campaigns, during which Perseus had maintained his ground against two consular armies. Philippus lost no time in crossing over into Greece, where he arrived early in the spring of B. C. 169, and received in Thessaly the army of the consul of the preceding year, A. Hostilius Mancinus. Here he did not remain long, but resolved to cross over the mountain ridge of Olympus and thus descend into Macedonia near Heracleium. Perseus was stationed with the main body of his forces near Dium, and had taken possession of the mountain passes which led into the plain. If Perseus had remained firm, he might have cut off the Roman army, or compelled it to retrace its steps across the mountains with great loss; but, at the approach of the consul, he lost courage, forfeited the advantages of his position, and retreated to Pydna. Philippus followed him, but was unable to accomplish any thing worthy of mention, and in the following year handed over the army to his successor L. Aemilius Paulus, who brought the war to a close. We learn from Livy that Philippus was at this time more than sixty years of age. In B. C. 164, Philippus was censor with L. Aemilius Paulus, and in his censorship he set up in the city a new sun dial. (Liv. 38.35, 39.6, 14, 20, 48, 40.2, 3, 42, 42.37-47, 43.13, 44.1_16; Plb. 24.4, 6, 10, 27.1, 28.10, &c.; Plin.
