This book covers Alexander the Great from his accession, through his campaigns in Persia, to his death in Babylon. Despite a promise in the brief prologue to discuss other contemporary events, it does not contain any side-narratives, although, unlike other accounts of Alexander, it does mention Macedonian activities in Greece during his expedition. Owing to its length, the book is split into two halves, the first running down to the Battle of Gaugamela (1-63) and the second part continuing until his death (64-118).
