In Bk. 3 of the Institutio oratoria, Quintilian gives a list of the Greek artium scriptores of the classical epoch. It contains a controversial entry: ‘…et, quem Palameden Plato appellat, Alcidamas Elaites’. The historicity of the rhetorician and sophist from Elaea named Alcidamas, Gorgias' pupil, is of course beyond doubt; scholars disagree only as to the ‘quem Palameden Plato appellat’.
