It is over a decade since the second edition of the highly successful sourcebook appeared, during which period a number of additions to our documentary evidence have surfaced, together with emendations to the names of both tribes and individuals. The main addition to the work, however, will be the inclusion of Caesar's commentaries on his two expeditions to Britain and the relevant sections of Tacitus' biography of his father-in-law.

- Menander, The Shield and Arbitration, Oxford 2010.
Menander is the only representative of Greek New Comedy to have survived from antiquity, and even then he remained a largely unknown author till discoveries of text in Egypt in the early 20th century. The edition of two plays, Aspis (The Shield) and Epitrepontes (Arbitration) forms part of the Aris & Phillips series, providing text, translation, and commentary based largely on the translation.
