Philetaerus in Harpers Dictionary of Classical Antiquities (1898)

（Φιλέταιρος). The founder of the kingdom of Pergamum, a native of Paphlagonia (Strabo, pp. 543, 623). He had served in the army of Antigonus and later in that of Lysimachus, who put him in charge of the treasure stored at Pergamum. Philetaerus, shifting for himself, declared in favour of Seleucus (q.v.), but after the death of the latter (B.C. 280) practically established his own independence, and on his death (B.C. 263) left the government to his nephew Eumenes (Lucian, Macrob. 12).
