(Ὀρσάβαρις), a daughter of Mithridates the Great, who was taken prisoner by Pompey, and served to adorn his triumph, B. C. 61 (Appian, App. Mith. 117). The name Orsobaris occurs also on a coin of the city of Prusias, in Bithynia. which bears the inscription ΒΑΣΙΛΙΣΣΗΣ ΜΟΤΣΗΣ ΟΠΣΟΒΑΠΙΟΣ ; and this is conjectured by Visconti (Iconogr.Grecque, tom. ii. p. 195) to refer to the same person as the one mentioned in Appian, whom he supposes to have been married to Socrates, the usurper set up by Mithridates as king of Bithynia.
