Philippus
25. A brother of Perseus, king of Macedonia, apparently a son of Philip by a subsequent marriage, as he was so much younger than his brother, that the latter adopted him as his son, and appears to have continued to regard him as the heir to his throne even after the birth of his own son Alexander. Thus we find him holding the post of honour next to the king on occasions of state; and after the fatal battle of Pydna he was the constant companion of Perseus during his flight and the period of his refuge at Samothrace, and surrendered together with him to the Roman praetor Cn. Octavius. He was led in triumph before the car of Aemilius Paulus, B. C. 167, and afterwards consigned to captivity at Alba, where he survived his adopted father but a short time. (Liv. 42.52, 44.45, 45.6; Plut. Aemil. 33, 37; Zonar. 9.24.) According to Polybius (Fr. Vat. xxxvii. p. 447) he was only eighteen years old at the time of his death.
