3. An Athenian rhetorician, a contemporary of Cicero, who calls him by far the most eloquent man in Greece. He was a great admirer of Demosthenes, whose speeches he commended to the attention of his pupils. M. Brutus studied under him. (Cic. Brut. 97, Orat. 100.30.) It is probably another Pammenes, of whom we know nothing, who is mentioned by Cic. Att. 5.20.10, 6.2.10.)
