Philological and Historical Commentary on Ammianus Marcellinus XXVII
J. den Boeft, J.W. Drijvers, D. den Hengst, H.C. Teitler
Book 27 deals with events between 365 and 370. Military operations in the western and eastern half of the Empire take up a large part of the available space. Apart from military matters Ammianus deals with internal affairs. He discusses the terms of office of four Roman urban prefects and paints a picture of Petronius Probus, the mightiest civil official of the period. The most striking part of the book contains a portrait of the emperor Valentinian. This passage forms the centre of the book, which therefore has the structure of a triptych: of the two outer parts each contains military affairs in the West and the East and reports on some notable non-military events, whilst in the central panel Valentinian takes pride of place.
