36. Of PERGAMUS, surnamed Atticus, a rhetorician, who is characterized by Strabo (xiii. p.625) as a clever sophist, an historian, and logographer, that is, a writer of orations. He was a pupil of Apollodorus, the rhetorician, who is mentioned among the teachers of Augustus. (Comp. Senec. Controv. 1.1.) Weiske (ad Longin. p. 218) considers him to be the author of the work περὶ ὕψους commonly attributed to Longinus; but there is very little, if anything, to support this view. (Westermann, Gesch. d. Griech. Beredts. § 98, note 9.)
