Note 10 — Chapter LXXXIII · SICILIAN AFFAIRS (continued). — FROM THE DESTRUCTION OF THE CARTHAGINIAN ARMY BY PESTILENCE BEFORE SYRACUSE, DOWN TO THE DEATH OF DIONYSIUS THE ELDER. B. C. 394-367.

Diodor. xiv. 88. μετὰ δὲ τὴν ἀτυχίαν ταύτην, Ἀκραγαντῖνοι καὶ Μεσσνήνιοι τοὺς τὰ Διονυσίου φρονοῦντας μεταστησάμενοι, τῆς ἐλευθερίας ἀντείχοντο, καὶ τῆς τοῦ τυράννου συμμαχίας ἀπέστησαν.

It appears to me that the words καὶ Μεσσνήνιοι in this sentence cannot be correct. The Messenians were a new population just established by Dionysius, and relying upon him for protection against Rhegium: moreover they will appear, during the events immediately succeeding, constantly in conjunction with him, and objects of attack by his enemies.

I cannot but think that Diodorus has here inadvertently placed the word Μεσσνήνιοι instead of a name belonging to some other community—what community, we cannot tell.
