or SCYLITZA, JOANNES, a Byzantine historian, of the later period of the empire, surnamed, from his office, CUROPALATES (Ἰωάννης Κουροπαλάτης ὁ Σκυλίτζης); probably also called (apud Cedren. Compend. sub init.) JOANNES THRACESIUS, and, from his office, PROTOVESTIARIUS (ὁ πρωτοβεστιάριος Ἰωάννης ὁ Θρακήσιος τὸ ἐπώνυμον). According to the account given by Fabricius and Cave, and which is now generally received, he was a native of the Thracesian Thema (which nearly corresponded to the Roman proconsular Asia), and attained successively at the Byzantine court, the dignities of protovestiarius (high chamberlain), magnus drungarius vigiliarum (captain of the guards), and curopalates. He flourished as late as A. D. 1081, if not later.
