(43) A century ago, a scholar attempted to restore the Life of Epaminondas by bringing together quotations (with analyses) using not only an array of passages from Plutarch (some not having directly to do with Epaminondas), but also passages from Cornelius Nepos, Xenophon, Diodorus Siculus, Cicero, Polyaenus, and others to fit the passages together.
Plato and Aristotle and that whole crowd of sages, heading as they were in different directions, drew more from Socrates' ways than from his words; Metrodorus and Hermarchus and Polyaenus, all great men--it was not Epicurus's school that made them such, but his com-raderie [contubernium].
& stratagemes.(14) The Stratagems of Polyaenus -- a work obscure now, but evidently popular in Sidney's day -- does not appear in Sidney's list of 'essential reading', so we cannot tell whether his account of Aristomenes had any influence;(15) but Messenia and its hero figure in books which we know (from the letter to Denny) that Sidney did read: Plutarch,(16) Polybius,(17) and Diodorus Siculus.(18)
