Prusias II of Bithynia in Wikipedia
Prusias II Cynegus ("the Hunter", c. 182 – 149 BC) was the king of Bithynia. He was the son and successor of Prusias I and Apama III.
Prusias joined with Eumenes of Pergamon in a war against Pharnaces I of Pontus (181 - 179 BC). He later invaded the territories of Pergamon (156 - 154 BC), only to be defeated, and the Pergamenes insisted on heavy reparations. Prusias married his maternal cousin Apame IV, a princess from the Antigonid dynasty, by whom he had a son called Nicomedes II. He sent his son Nicomedes II to Rome to ask their help in reducing the amount of these reparations, but Nicomedes revolted and became King.
Prusias in Harpers Dictionary of Classical Antiquities (1898)
II. King of Bithynia, son and successor of the preceding, reigned from about B.C. 180 to 149. He courted assiduously the alliance of the Romans. He carried on war with Attalus, king of Pergamus, with whom, however, he was compelled by the Romans to conclude peace in 154. He was slain in 149 by order of his son Nicomedes, as is related in the life of the latter. (See Nicomedes II.) Prusias is described to us as a man in whom personal deformity was combined with a character the most vicious and degraded. His passion for the chase is attested by the epithet of the "Huntsman" (Κυνηγός) given to him (Polyb. xxiv. 1).
