Real Roman History

• Cassius Dio. Roman History, Books 54–55. The reorganization of the army under Augustus, with Book 55, chapter 25 covering the establishment of the aerarium militare in 6 CE.
• Egyptian papyri. Collected most accessibly in Robert O. Fink, Roman Military Records on Papyrus. American Philological Association, 1971. Pay records, duty rosters, personal correspondence—the only surviving documentary evidence of this volume from anywhere in the Roman world.
• Josephus. Jewish War, Book 3, chapters 5 and 6. The famous Greek-language description of the Roman army of the late 60s CE, written by a former enemy commander who had real reason to understand how the army worked. The best surviving outsider's account.
• Military diplomas. The bronze citizenship grants issued to discharged auxiliaries. Catalogued across the Roman Military Diplomas series and standard epigraphic corpora.
• Suetonius. Life of Augustus, chapters 24–25 and 49. On Augustus's military reforms, the founding of the aerarium militare, and his attitudes toward discipline.
• Tacitus. Annals, 1.16–49. The Pannonian and Rhine mutinies of 14 CE—the army from inside, complaining about pay, discipline, and conditions. The clearest narrative window on what serving in the army felt like.
• The Vindolanda tablets. Published by Alan K. Bowman and J. David Thomas across multiple volumes since 1983. The most vivid evidence for daily life on a frontier post. The birthday party invitation of Claudia Severa is Tablet 291 in the standard numbering.
• Vegetius. Epitoma Rei Militaris, late fourth century CE. The single most extensive surviving Roman military manual. Written long after the period of this episode and partly archaizing—Vegetius is looking back to an idealized earlier army he believed had since deteriorated—but invaluable when used with care. The Loeb edition, translated by N. P. Milner, is the standard.

• Bowman, Alan K. Life and Letters on the Roman Frontier: Vindolanda and Its People. Third edition, British Museum Press, 2003. The best introduction to the Vindolanda evidence for general readers.
• Goldsworthy, Adrian. The Complete Roman Army. Thames and Hudson, 2003. The standard modern treatment, and the structural reference for this episode.
• Keppie, Lawrence. The Making of the Roman Army: From Republic to Empire. Revised edition, Routledge, 1998. The best account of the transition from the Republican army to the Augustan one.
• Luttwak, Edward N. The Grand Strategy of the Roman Empire. Johns Hopkins University Press, 1976; revised edition, 2016. Influential and contested account of the political logic of the frontier system. Worth reading with a critical eye.

• Calendar inscriptions and Acta Arvalia. The Fasti Verulani and Fasti Praenestini record her birthday and her death anniversary as public observances. The Acta Arvalia preserve the priestly vows for her health during the 22 CE illness and at other moments of crisis.
• Cassius Dio. Roman History, Books 57 and 58. The continuous Greek-language narrative. Book 58.2 contains the obituary passage acknowledging Livia's restraining and humane influence.
• Senatus Consultum de Cn. Pisone Patre. The bronze decree of December 10, 20 CE, recording the Senate's verdict in the trial of Cn. Calpurnius Piso. A copy was found at Itálica in Spain in 1988 and published by Werner Eck, Antonio Caballos, and Fernando Fernández in 1996. The single most important documentary witness to Livia's named, formally acknowledged role in Tiberian decision-making.
• Suetonius. Life of Caligula, chapters 7–10. Caligula's upbringing and the family context of the funeral oration in 29 CE.
• Suetonius. Life of Claudius, chapters 1–3. Claudius's childhood under Livia's eye. Contains the letter between Augustus and Livia debating his fitness for public appearances.
• Suetonius. Life of Tiberius, chapters 50–51. The central source for the mother-son deterioration. Chapter 50 catalogues Tiberius's specific evasions; chapter 51 closes with the death and his funeral absence.
• Tacitus. Annals, 1.6–14, 3.17, 3.64, 4.16, 5.1–3. The continuous Tacitean account of Livia's widowhood. Hostile in framing throughout, but the indispensable narrative source. The death scene and obituary are at 5.1–3.

• Barrett, Anthony A. Livia: First Lady of Imperial Rome. Yale University Press, 2002. The essential modern treatment. The first biography to fully incorporate the Piso decree, and the reference for almost every reconstruction in this episode.
• Damon, Cynthia, and Sarolta Takács, editors. The Senatus Consultum de Cn. Pisone Patre: Text, Translation, Discussion. American Journal of Philology Special Issue, 1999. The most accessible English-language treatment of the decree.
• Eck, Werner, Antonio Caballos, and Fernando Fernández. Das Senatus Consultum de Cn. Pisone Patre. C. H. Beck, 1996. The foundational publication of the bronze decree. In German, but the Latin text and apparatus are usable for any reader.
• Kleiner, Diana E. E. Cleopatra and Rome. Harvard University Press, 2005. Useful for the comparative framing of female political power in the late Republic and early empire.
• Wood, Susan. Imperial Women: A Study in Public Images, 40 BC–AD 68. Brill, 1999. The coin portraits and sculptural representations that document Livia's continuing public presence through the Tiberian and post-Tiberian periods.

• Cassius Dio. Roman History, Books 55–58. The most extensive narrative coverage. Contains information not found elsewhere, including the figs allegation. Book 58.2 records Dio's pause at her death to acknowledge what she had actually done—the strongest single passage in any ancient source on her humane and restraining influence.
• Inscriptional and papyrological evidence. The Augustus letter to the Samians (preserved in an inscription at Aphrodisias) is the key documentary witness for her actual administrative and patronage functions. Egyptian papyri provide comparative material for provincial-level patronage networks.
• Suetonius. Life of Augustus, chapters 62–63, 84. Coverage of the marriage to Livia, the story of the premature birth, the domestic texture of the marriage, and the note about Augustus writing down what he intended to say in important conversations with her.
• Suetonius. Life of Tiberius, chapters 50–51. Essential for the deteriorating relationship between Livia and her son after Augustus's death.
• Tacitus. Annals, 1.3–8, 3.64–65, 5.1–3. The most analytical ancient source. Annals 1.3–8 contains the famous summary of Augustus's reign and the charges against the dynasty, including the charge about the grandsons. Annals 5.1–3 covers Livia's death, Tiberius's absence from the funeral, and the senatorial honours Tiberius refused to confirm. Tacitus's portrait is complex rather than simply hostile.

• Barrett, Anthony. Livia: First Lady of Imperial Rome. Yale University Press, 2002. The essential modern treatment. Barrett examines every poisoning allegation systematically and finds no credible evidentiary support. His reconstruction of her administrative and patronage functions from the inscriptional evidence is the starting point for any serious engagement with the question. No subsequent biography has superseded it.
• Fantham, Elaine. Julia Augusti: The Emperor's Daughter. Routledge, 2006. Useful for the Julia material in Part Three.
• Wood, Susan. Imperial Women: A Study in Public Images, 40 BC–AD 68. Brill, 1999. Coverage of the coin portraits and sculptural representations that document Livia's public presence across the empire.

• Cassius Dio. Roman History, Book 56, chapters 18–24. The fullest ancient narrative of the battle, written two centuries after the events but drawing on earlier sources now lost. The most detailed account of the three-day engagement and the Roman collapse.
• Florus. Epitome of Roman History, Book 2, chapter 30. Brief but vivid account of the battle; supplements Dio on specific details.
• Josephus. Jewish War and Jewish Antiquities. The clearest account of Varus's tenure as governor of Syria and the suppression of the post-Herodian revolts.
• Museum und Park Kalkriese, Bramsche-Kalkriese, Lower Saxony, Germany. The archaeological site, excavated since 1987. The museum's published catalogues and the ongoing archaeological reports are primary sources for the physical evidence: the silver cavalry mask, the earthen rampart, the scattered Roman equipment and bones. Irreplaceable evidence for the battle's location and character.
• Suetonius. Life of Augustus, chapter 23. The court's reaction to the news: the torn clothes, the uncut hair, the cries of “Quinctili Vare, legiones redde.” Essential for Augustus's personal response and for the three legion numbers never reused.
• Tacitus. Annals, Book 1, chapters 55–71. Germanicus's campaigns in Germany and the discovery of the battlefield in 15 CE. Chapters 61–62 are the most extraordinary passage in the literary record: the bones, the altars, the skulls on the trees, the soldiers weeping.
• Tacitus. Annals, Book 2, chapter 88. The obituary of Arminius. The claim that Arminius is celebrated in Germanic song is the clearest acknowledgment in any Roman source of a Germanic tradition about the battle that the Roman literary record could not access.
• Velleius Paterculus. Roman History, Book 2, chapters 117–120. The contemporary eyewitness source. Velleius knew Varus personally and served under Tiberius; his account is the closest in time and the most partial in perspective. Essential for the portrait of Varus and the Roman reaction.

• Dreyer, Boris. Arminius und der Untergang des Varus. Klett-Cotta, 2009. The most thorough German-language treatment of the battle and Arminius's career; invaluable for the Germanic perspective and the Kalkriese evidence.
• Goldsworthy, Adrian. Augustus: First Emperor of Rome. Weidenfeld and Nicolson, 2014. Chapter on Teutoburg in the context of the late Augustan period.
• Murdoch, Adrian. Rome's Greatest Defeat: Massacre in the Teutoburg Forest. Sutton Publishing, 2006. Solid narrative account; good on Arminius's career before and after the battle.
• Wells, Peter S. The Battle That Stopped Rome: Emperor Augustus, Arminius, and the Slaughter of the Legions in the Teutoburg Forest. W. W. Norton, 2003. The best popular account incorporating the Kalkriese archaeology; excellent on the terrain and what the physical evidence reveals about the ambush's structure.
• Barrett, Anthony A. Livia: First Lady of Imperial Rome. Yale University Press, 2002. For context on the Augustan court's reception of the disaster.

• Cassius Dio. Roman History, Books 55–56. The narrative backbone for the decade.

• Wells, Peter S. The Battle That Stopped Rome: Emperor Augustus, Arminius, and the Slaughter of the Legions in the Teutoburg Forest. W. W. Norton, 2003. The best popular account of Teutoburg for the archaeological context at Kalkriese.
• White, Peter. “Ovid and the Augustan Milieu,” in Brill's Companion to Ovid (ed. Barbara Weiden Boyd). Brill, 2002. The best recent treatment of the exile and the likely political context of the carmen et error.

• Cassius Dio. Roman History, Books 54–55. The narrative backbone for this episode. Dio covers Agrippa's death in the closing sections of Book 54, and the main subsequent events in Book 55. He is working two centuries after the events from sources he does not name.
• Cenotaphia Pisana (CIL XI 1420–1421). The inscribed decrees from the town of Pisa voting public mourning for Lucius in 2 CE and for Gaius in 4 CE. Primary epigraphic evidence for how the deaths were received in provincial Italy.
• Macrobius. Saturnalia, Book 2. Preserving earlier collected anecdotes of Julia's wit. The late date (early fifth century CE) counsels caution, but the material has the texture of authentic first-century traditions.
• P. Colon. inv. 4701. The papyrus fragment of Augustus's funeral oration for Agrippa, preserved from Egypt and now held in the University of Cologne. One of the few documents in the Augustan corpus allowing us to hear the emperor in his own words.

• Suetonius. Life of Augustus, chapters 63–65. On Julia, the marriages, and the crisis of 2 BCE. The detail that Augustus wept composing the letter to the Senate and refused visitors for days afterward is chapter 65.
• Suetonius. Life of Tiberius, chapters 7–15. The central character source for Tiberius in this period. The Vipsania-in-the-street passage is chapter 7. The Rhodes withdrawal and the years on the island are chapters 10–13.
• Tacitus. Annals, Book 1. Retrospective from the Tiberian reign, essential for political analysis but coloured by what Tiberius became as emperor.
• Velleius Paterculus. Roman History, Book 2, chapters 96–102. The most important contemporary witness. Velleius served under Tiberius in Germany and under Gaius Caesar in Armenia. He is an eyewitness for the Artagira incident in 3 CE.

This episode has been drafted primarily from Suetonius's Life of Augustus. Suetonius was writing in the early second century CE, a century after Augustus's death, with access to the imperial archives as Hadrian's private secretary. Almost all the physical description, the working habits, the superstitions, and the details of the household come from his Life. In the cases where they do not come from Suetonius, they are usually in Cassius Dio, writing another century later still from Greek-speaking Bithynia in Asia Minor—modern northwestern Turkey.

Both sources have limitations. Suetonius is thematic, rather than chronological. He groups anecdotes by category—ancestry, physique, virtues, vices, notable sayings, superstitions, death—rather than narrating events in order. This makes his Life of Augustus a strange reading experience for a modern biographer, because it is not really a biography, in our sense. It is a character portrait assembled from archival material and organised by theme. It is also, in places, organised to illustrate a moral conclusion Suetonius has already reached. When he reports that Augustus was moderate in his diet and modest in his household, he is not only telling us what the archive says. He is also telling us what a good emperor ought to look like, and holding Augustus up as the example.

Dio is more chronological, but further from the events and working, for this period, from sources he does not name. His account of the 23 BCE illness is the fullest we have. It is not necessarily the most accurate, because the details of a sickroom scene reach him across two centuries, and what he records may already have been shaped by the political uses to which the story was put.

What neither of them can see is the ordinary population of the empire. Augustan Rome had roughly a million inhabitants. The Italian peninsula had perhaps six million. The empire, from Spain to the Euphrates, held fifty or sixty million. Almost nothing in Suetonius or Dio is about any of them. The empire that Augustus administered through his correspondence did not, in the sources, contain the people it was administering. Tacitus's famous analytical verdict, quoted last episode, that the principate was built on grain for the people, bonuses for the army, and the sweetness of peace for everyone else, is, among other things, the rare ancient moment when one of the senatorial historians looks outside the senatorial chamber and names who the settlement was actually for. It was for the soldiers who got their pay, for the urban poor who got their grain, and for the propertied classes who got safety. The people it was paid for by were the provinces, which Augustus governed, but the sources do not describe.

That absence is the largest thing about the Augustan period that the literary tradition does not tell us. The archaeology is doing some of that work now. The inscriptions, the papyri from Egypt, the provincial census records—these are being used by modern scholars to recover the empire that Augustus built for other people to live in. In this episode, I have followed the literary sources because the character portrait is what they are best at, and because the question of who Augustus was as a person is the question the sources were actually trying to answer.

• Cassius Dio. Roman History, Books 52–53. The fullest narrative of the settlement years and the 23 BCE illness.

• Horace. Odes, Books 1–3. Published in 23 BCE, the same year as the illness.
• Res Gestae Divi Augusti. Augustus's own account, read as the official version.
• Suetonius. Life of Augustus. The indispensable source for character, physical detail, working habits, and household.

• Augustus. Res Gestae Divi Augusti (“The Deeds of the Divine Augustus”). Augustus's own first-person summary of his career and achievements, inscribed on bronze tablets and posted throughout the empire. The religious restoration is mostly in chapters 8, 10, 12, 13, 20, and 21—the temple restorations, the Janus closures, the Ara Pacis, the assumption of the Pontifex Maximus. Loeb Classical Library edition (with English translation).
• Cicero. De Divinatione (45 BCE). The Roman intellectual position on augury and divination, written by a sitting augur. Book One defends divination; Book Two demolishes it. Loeb Classical Library edition.
• Cicero. De Natura Deorum (45 BCE). The fullest ancient account of educated Roman thinking about the gods. Three speakers representing the Epicurean, Stoic, and Academic positions. Loeb Classical Library edition.
• Livy. History of Rome. Numa and his religious institutions are in Book 1. The first lectisternium is in Book 5. The Cybele arrival in 204 BCE is in Book 29. The Bacchanalian crisis of 186 BCE is in Book 39—the longest single ancient narrative of a Roman religious panic. Penguin Classics translation by Aubrey de Sélincourt for the early books; Loeb editions cover the rest.
• Lucretius. De Rerum Natura (mid-first century BCE). The major surviving Epicurean text, and one of the greatest works of Latin verse.

Penguin Classics translation by Ronald Melville.
• Ovid. Fasti (early first century CE). The Roman religious calendar in verse—six surviving books, one for each month from January to June. The single best ancient source for the festivals and rituals that punctuated the Roman year, including the Cybele/Claudia Quinta episode in Book 4. Penguin Classics translation by A.J. Boyle and R.D. Woodard.
• Plutarch. Parallel Lives. The Life of Numa is the major ancient narrative of Rome's religious founder. The Lives of Caesar, Cicero, and Antony provide most of what we know about the religious dimensions of the late Republic—Caesar's election as Pontifex Maximus, Cicero's augural service, the propaganda war of the 30s. Penguin Classics translations available for all the relevant Lives.
• Senatus Consultum de Bacchanalibus (186 BCE). The surviving bronze decree, now in the Kunsthistorisches Museum in Vienna.

Aeneas's pietas as the organizing virtue of the poem, the burning of Troy and the rescue of the household gods in Book 2, the descent and the parade of future Romans in Book 6. Robert Fagles translation (Penguin Classics) is the standard modern English version.
