What this dot point is asking
The Roman topics rest on a set of historians and documents, and knowing their methods, strengths and limitations is essential for the source questions. This page surveys Tacitus, Suetonius, Cassius Dio and Cicero, and the documentary sources (the Res Gestae, coins and inscriptions), for the Julio-Claudian period and the Late Republic, and shows how to evaluate them. It underpins both the period study and the depth study.
The answer
Tacitus and Suetonius
The two are best compared on the same event (the fire of Rome, the death of Agrippina): Tacitus is generally the more reliable in method, Suetonius the richer in anecdote, and both are hostile.
Cassius Dio and Cicero
Cicero's letters are the one source written in the moment, which makes them the essential contemporary check on the later narratives (Plutarch, Appian, Dio) and on the self-serving accounts (Caesar).
The documentary sources
The Roman topics also use documentary evidence, which must be read for its purpose:
- The Res Gestae is Augustus's own propaganda, valuable for his self-image and official ideology, limited as neutral record.
- Coins carry imperial messages (titles, honours, images of the family and succession), valuable for what the regime wished to project.
- Inscriptions record offices, honours and public works, valuable for official acts and self-presentation.
The skill across all the Roman sources is to evaluate each for the enquiry, comparing the hostile literary narratives with the official documents and the contemporary Cicero, and using their limitations as evidence.
Examples in context
A model answer compares the value of the sources for the enquiry and uses method and purpose as the basis of evaluation.
Try this
Q1. "Cicero's letters are the most valuable source for the Late Republic." Assess how far you agree. [20 marks, sources style]
- What the marker wants. An argument weighing the unique value of Cicero's contemporary, candid letters against their partisan, personal nature, compared with the later narratives (Plutarch, Appian, Dio) and the self-serving Caesar, with a judgement on their value for the period.
Q2. Why must the Res Gestae and imperial coins be read as official sources? [2 marks]
- Cue. Because they were produced by the regime to project its chosen self-image (Augustus's achievements, imperial titles and honours), so they are valuable for official ideology rather than as neutral records.

OCR H407/21 202012 marksHow useful is Tacitus as a source for the Julio-Claudian emperors, compared with Suetonius? [generic Roman-sources question, shown at the 12-mark style]Show worked answer →
A generic AO3 question on the Roman historians, shown at the 12-mark style.
Tacitus. The fullest and most analytical narrative of the Julio-Claudians, penetrating on court politics and power, but senatorial, moralising and hostile to the emperors, with composed speeches and gaps where his text is lost.
Suetonius. A biographer organised by themes and vices, rich in anecdote and detail, but fond of scandal and the marvellous, less analytical, and writing to characterise rather than to analyse causation.
Judgement. Both are indispensable, but Tacitus is generally the more reliable in method while Suetonius is richer in anecdote; each must be evaluated for the enquiry, and they are best compared on the same event. Top answers compare value rather than describing.
OCR H407/21 202212 marksHow useful are Cicero's letters as a source for the Late Republic? [generic Roman-sources question, shown at the 12-mark style]Show worked answer →
A generic AO3 question on Cicero, shown at the 12-mark style.
Value. Cicero's letters are contemporary and written in the moment without hindsight, by a central participant, so they are uniquely valuable for the real-time politics, alliances and anxieties of the period (the Triumvirate, the civil war), and for candid opinion.
Limitations. They are personal and partisan (Cicero has his own interests, prejudices and self-image), often written to persuade or impress a correspondent, so they must be read for purpose and audience; they reflect one viewpoint.
Judgement. Uniquely valuable as contemporary, candid evidence, but partisan and personal, to be tested against the later narratives. Top answers judge value for the enquiry.
