A Dictionary of Greek and Roman biography and mythology

2. Of Tarentum, and a follower of Pythagoras (Iamblich. Vit. Pyth.). Fabricius conjectures (Bibl. Graec. vol. i. p. 864) that he is the same with Polyarchus, surnamed ἡδυπαθής, who is mentioned by Athenaeus (xii. p. 545), as having been sent by Dionysius the younger, on an embassy to Tarentum, where, being intimate with Archytas, he dilated to that philosopher on the excellency of pleasure; his discourse being given by Athenaeus, on the authority of Aristoxenus. But this seems an unhappy conjecture. The doctrines ascribed to Polyarchus are certainly not those of the school of Pythagoras; nor is it even hinted that he was a native of Tarentum.
