In JHS cv (1985) 162–8, J. L. Moles has given an excellent treatment of the literary influences at work in the ‘second preface– of Arrian's Anabasis (i 12.1–5). I am in agreement with the main points of his work, and the purpose of the present note is to offer some additional evidence and suggestions.
1. Literary influences. Moles sees five major influences at work in the second preface: Homer, Herodotus, Thucydides, Xenophon, and the prose encomium. Of this last he writes (164), ‘Arrian's work will be biographical in orientation and fundamentally encomiastic’. There is no doubt, of course, that Arrian's work is encomiastic; Arrian does not hesitate to express admiration for Alexander at the outset of the work or in comments throughout the work or in the επιμετρῶν λόγος at the work's conclusion. But Arrian's history is not an encomium, though it may incorporate elements from that genre.
