 The only complete account is Diodorus Siculus's "Bibliotheca historica", which was also the first to be written, c. 40 BC, and should thus be considered the more reliable source.The Byzantine bishop Photius (c. 820–893) produced an epitome of 279 books in his "Bibliotheca", which contains two relevant (but much abbreviated) accounts.The first is Arrian's "Continuation" or "After Alexander" (codex 92).
