[260] Cornelius Nepos, Dion. c. 7. “Insuetus male audiendi,” etc.
[261] Plutarch, Dion, c. 56. Ἀλλ᾽ ὁ μὲν Δίων, ἐπὶ τοῖς κατὰ τὸν Ἡρακλείδην ἀχθόμενος, καὶ τὸν φόνον ἐκεῖνον, ὥς τινα τοῦ βίου καὶ τῶν πράξεων αὐτῷ κηλῖδα προκειμένην, δυσχεραίνων ἀεὶ καὶ βαρυνόμενος εἶπεν, ὅτι πολλάκις ἤδη θνήσκειν ἕτοιμός ἐστι καὶ παρέχειν τῷ βουλομένῳ σφάττειν αὐτὸν, εἰ ζῇν δεήσει μὴ μόνον τοὺς ἐχθροὺς ἀλλὰ καὶ τοὺς φίλους φυλαττόμενον.
Compare Plutarch, Apophthegm. p. 176 F.
[262] Plato, Epistol. vii. p. 333 F.: compare Plutarch. Dion. c. 17, 28, 54.
Athenæus, on the contrary, states that Kallippus was a pupil of Plato, and fellow pupil with Dion in the school (Athenæus, xi. p. 508).
The statement of Plato hardly goes so far as to negative the supposition that Kallippus may have frequented his school and received instruction there, for a time greater or less. But it refutes the idea, that the friendship of Dion and Kallippus arose out of these philosophical tastes common to both; which Athenæus seems to have intended to convey.
[263] Plutarch, Dion, c. 54; Cornelius Nepos, Dion, c. 8.
[264] Plutarch, Dion. c. 56.
[265] Plato alludes to the two brothers whom Dion made his friends at Athens, and who ultimately slew him; but without mentioning the name of either (Plato, Epistol. vii. p. 333 F.).
The third Athenian—whose fidelity he emphatically contrasts with the falsehood of these two—appears to mean, himself—Plato. Compare pp. 333 and 334.
