(Λόγγος), a Greek sophist, who is believed to have lived in the fourth or at the beginning of the fifth century of our era. Concerning his history nothing is known, but it is probable that he lived after the time of Heliodorus, for there are some passages in his work which seem to be imitations of Heliodorus of Emesa.
