(Καύκαλος), of Chios, a rhetorician, of whom an culogium on Heracles is mentioned by Athenaeus (x. p. 412), who also states that he was a brother of the historian Theopompus. It is very probable, that Suidas and Photius (s. v. Λήμνιον κακόν) refer to our rhetorician, itn which case the name Καύκασος must be changed into Καύκαλος.
