Agathocles of Syracuse
The narrative of the book continues the account of the Diadochi, recounting the Second and Third Wars of the Diadochi; the Babylonian War is completely unmentioned. Interwoven in this narrative is the rise to power of Agathocles of Syracuse and the beginning of his war with Carthage. It is disputed whether this latter narrative strand is based on Callias of Syracuse, Timaeus of Tauromenium, or Duris of Samos.
