Note 109 — Chapter LXXVI · FROM THE PEACE OF ANTALKIDAS DOWN TO THE SUBJUGATION OF OLYNTHUS BY SPARTA.

This is attested by Plato, Gorgias, c. 26. p. 471 A.

... Ὅς γε (Archelaus son of Perdikkas) πρῶτον μὲν τοῦτον αὐτὸν τὸν δεσπότην καὶ θεῖον (Alketas) μεταπεμψάμενος, ὡς ἀποδώσων τὴν ἀρχὴν ἣν Περδίκκας αὐτὸν ἀφείλετο, etc.

This statement of Plato, that Perdikkas expelled his brother Alketas from the throne, appears not to be adverted to by the commentators. Perhaps it may help to explain the chronological embarrassments connected with the reign of Perdikkas, the years of which are assigned by different authors, as 23, 28, 35, 40, 41. See Mr. Clinton, Fasti Hellen. ch. iv, p. 222—where he discusses the chronology of the Macedonian kings: also Krebs, Lection. Diodoreæ, p. 159.

There are no means of determining when the reign of Perdikkas began—nor exactly, when it ended. We know from Thucydides that he was king in 432, and in 414 B.C. But the fact of his acquiring the crown by the expulsion of an elder brother, renders it less wonderful that the beginning of his reign should be differently stated by different authors; though these authors seem mostly to conceive Perdikkas as the immediate successor of Alexander, without any notice of Alketas.
