ABSTRACT
The comparatively large allocation of space to Sicilian affairs, specifically to the first part of Dionysius' reign, and the three out of four major speeches in surviving portions of the Bibliotheke, derived from the Sicilian narrative that is perfectly understandable phenomena given Diodorus' the Sicilian origin. Notwithstanding the comparatively recent attempts by the scholars emanating from the University of Palermo advances the claim of Silenus of Caleacte as Diodorus' the chief source for his account of all Sicilian history, including the narrative of Dionysius' reign. Volquardsen further argued that as Diodorus' notice on the date which marked the close of the first part of Philistus' work that appears in the narrative of the Peloponnesian War and not in the narrative of Sicilian history. The Ephorus' second Dionysian book stressed the Dionysius' role within the context of universal Greek history, rather than that of Sicily, it would perhaps have been on such grounds less appealing to Diodorus, the Sicilian nationalist.
