speech, for the ruin of rivals and for his own exaltation. [219] Plato, Epist. iv. p. 321 B. ... ἐνθυμοῦ δὲ καὶ ὅτι δοκεῖς τισὶν ἐνδεεστέρως τοῦ προσήκοντος θεραπευτικὸς εἶναι· μὴ οὖν λανθανέτω σε ὅτι διὰ τοῦ ἀρέσκειν τοῖς ἀνθρώποις καὶ τὸ πράττειν ἐστίν, ἡ δ᾽ αὐθάδεια ἐρημίᾳ ξύνοικος. [220] Plutarch, Dion, c. 32. As the contest presently came to be carried on rather at sea than on land, the equipment of a fleet became indispensable; so that Herakleides, who had brought the greatest number of triremes, naturally rose in importance. Shortly after his arrival, the Syracusan assembly passed a vote to appoint him admiral. But Dion, who seems only to have heard of this vote after it had passed, protested against it as derogating from the full powers which the Syracusans had by their former vote conferred upon himself. Accordingly the people, though with reluctance, cancelled their vote, and deposed Herakleides. Having then gently rebuked Herakleides for raising discord at a season when the common enemy was still dangerous, Dion convened another assembly; wherein he proposed, from himself, the appointment of Herakleides as admiral, with a guard equal to his own.[221] The right of nomination thus assumed displeased the Syracusans, humiliated Herakleides, and exasperated his partisans as well as the fleet which he commanded. It gave him power—together with provocation to employ that power for the ruin of Dion; who thus laid himself doubly open to genuine mistrust from some, and to intentional calumny from others. [221] Plutarch, Dion, c. 33. It would seem that this Herakleides is the person alluded to in the fragment from the fortieth Book of the Philippica of Theopompus (Theop. Fr. 212, ed. Didot):— Προστάται δὲ τῆς πόλεως ἦσαν τῶν μὲν Συρακουσίων Ἄθηνις καὶ Ἡρακλείδης, τῶν δὲ μισθοφόρων Ἀρχέλαος ὁ Δυμαῖος. Probably also, Athênis is the same person named as _Athanis_ or _Athanas_ by Diodorus and Plutarch, (Diodor. xv. 94; Plutarch, Timoleon, c. 23-37). He wrote a history of Syracusan affairs during the period of Dion and Timoleon, beginning from 362 B. C., and continuing the history of Philistus. See Historicorum Græc. Fragm. ed. Didot, vol. ii. p. 81.
