This chapter deals with the main issues bearing upon Clitarchus and his work, moving beyond the usual division between Testimonia and Fragmenta and giving attention to the context and the agenda of each writer that mentioned him. Attention is given to his popularity as an Alexander historian and as a fine writer, as well as to the real significance of the narrative material attributed to him. This evidence can be combined with his few known biographical details in the evaluation of his chronology, which remains uncertain. The last two sections, dealing with his chronology and with the presentation of Alexander in his work, end with a question mark and invite the reader’s own reflections.
