Potamo or Potamon (Greek: Ποτάμων ὁ Μυτιληναῖος; around 65 BC–around AD 25)[1]) of Mytilene in Lesbos,[2] son of Lesbonax the rhetorician, was himself a rhetorician in the time of the Roman emperor Tiberius, whose favour he enjoyed.
[4] It is probably he whom Lucian states to have attained the age of ninety.
[5] When his son was killed, according to Seneca the Elder, he delivered a speech on the suasoria relating to the Spartans deliberating whether to flee Thermopylae wherein he exhorted the Spartans against flight, in contrast to his rival Lesbocles,[1] who shut down his school of rhetoric after the death of his son.
[1] The Suda informs us that, in addition to his work On Alexander of Macedon (Περὶ Ἀλεξάνδρου τοῦ Μακεδόνος), he wrote several other works, namely: To these should perhaps be added On the Different, quoted by Ammonius Grammaticus.
