Diodor. xviii, 58. ἧκε δὲ καὶ παρ᾽ Ὀλυμπιάδος αὐτῷ γράμματα, δεομένης καὶ λιπαρούσης βοηθεῖν τοῖς βασιλεῦσι καὶ ἑαυτῇ· μόνον γὰρ ἐκεῖνον πιστότατον ἀπολελεῖφθαι τῶν φίλων, καὶ δυνάμενον διορθώσασθαι τὴν ἐρημίαν τῆς βασιλικῆς οἰκίας.
Cornelius Nepos, Eumenes, 6. “Ad hunc (Eumenem) Olympias, quum literas et nuntios misisset in Asiam, consultum, utrum repetitum Macedoniam veniret (nam tum in Epiro habitabat) et eas res occuparet—huic ille primum suasit ne se moveret, et expectaret quoad Alexandri filius regnum adipisceretur. Sin aliquâ cupiditate raperetur in Macedoniam, omnium injuriarum oblivisceretur, et in neminem acerbiore uteretur imperio. Horum illa nihil fecit. Nam et in Macedoniam profecta est, et ibi crudelissime se gessit.” Compare Justin, xiv. 6; Diodor. xix. 11.
The details respecting Eumenes may be considered probably as depending on unusually good authority. His friend Hieronymus of Kardia had written a copious history of his own time; which, though now lost, was accessible both to Diodorus and Plutarch. Hieronymus was serving with Eumenes, and was taken prisoner along with him by Antigonus; who spared him and treated him well, while Eumenes was put to death (Diodor. xix. 44). Plutarch had also read letters of Eumenes (Plut. Eum. 11).

[802] Plutarch (Eumenes, 16-18), Cornelius Nepos (10-13), and Justin (xiv. 3, 4) describe in considerable detail the touching circumstances attending the tradition and capture of Eumenes. On this point Diodorus is more brief; but he recounts at much length the preceding military operations between Eumenes and Antigonus (xix. 17, 32, 44).
The original source of these particulars must probably be, the history of Hieronymus of Kardia, himself present, and copied, more or less accurately, by others.
