Polyaenus
2. Of LAMPSACUS, the son of Athenodorus, a mathematician and a friend of Epicurus, adopted the philosophical system of his friend, and, although he had previously acquired great reputation as a mathematician, he now maintained with Epicurus the worthlessness of geometry. (Cic.
de Fin. 1.6,
Acad. 2.33;
D. L. 10.24,
2.105, with the note of Menagius.)
It has been supposed that it was against this Polyaenus that the treatise was written, a fragment of which has been discovered at Herculaneum under the title of
Δημητρίου πρὸς τὰς Πολυαίνου ἀπορίας. (Schöll,
Geschichte d. Griech. Litteratur, vol. ii. p. 209.)
