2. A son of Nicomedes II., king of Bithynia, who was placed by his father on the throne of Paphlagonia, and made to assume the name of Pylaemenes, in order that he might appear to belong to the rightful line of the kings of that country. (Just. 37.4.) He was afterwards expelled by Mithridates the Great, in B. C. 90 (Eutrop. 5.5), and it does not appear that he himself ever recovered his throne: but after the final overthrow of Mithridates, the sons of Pylaemenes were reinstated by Pompey in the possession of some part of their father's dominions with the title of king. (Strab. xii. p.541.)

There are extant coins bearing the titles ΒΑΣΙΛΕΩΣ ΠΥΛΑΙΜΕΝΟΥ ΕΥΕΡΓΕΤΟΥ, which may probably be ascribed to one of the two preceding kings, but it is impossible to say to which they belong. (Eckhel, vol. ii. p. 394.)
