This volume presents the Latin text, accompanied by an introduction and a detailed commentary, of the biography of the emperor Claudius written by the early second-century AD author Suetonius. The commentary provides context for the factual and anecdotal information given in the text and also explains the author's method of composition and provides help with difficult grammatical points. The introduction contains sections on Suetonius, Claudius, and the text itself. This is the first English commentary on the Claudius Life to deal with both historical and stylistic issues.
