3. A general of Tigranes or Mithridates, who together with Mithraus expelled Ariobarzanes from Cappadocia in B. C. 92. (Appian, App. Mith. 10; comp. Justin, 38.3.)

The name Bagoas frequently occurs in Persian history. According to Pliny (Plin. Nat. 13.9), it was the Persian word for an eunuch; and it is sometimes used by Latin writers as synonymous with an eunuch. (Comp. Quint. Inst. 5.12; Ov. Am. 2.2. 1.)
