5. A Syracusan, who, together with Sosistratus, obtained the chief direction of affairs in his native city, shortly before the elevation of Agathocles in B. C. 317. Diodorus tells us (19.3) that they were both men who had attained to power by every species of treachery and crime; but the details to which he refers as having been given in the preceding book, are lost. (See Wesseling, ad l.c.) We find them both mentioned as the leaders of an expedition sent by the Syracusans against Crotona and Rhegium in Italy, in which Agathocues also took part; but it is not clear how far Heracleides was connected with the subsequent events which terminated in the temporary elevation of Sosistratus to the supreme power. [SOSISTRATUS] (Diod. 19.3, 4.)
