One of the greatest challenges to modern historians of Rome is the Romans’ own seeming lack of interest in writing their own history for their first 600 years. While, according to Roman legend, Rome was founded in 753 BCE, the first Roman history in Latin, Origins, composed by the Republican politician Cato the Elder, was not published until 149 BCE. A few senators had written about Roman history in Greek earlier on, and some aristocrats kept family histories, but Cato’s work was truly the first Roman history on a large scale, as it narrated events from the foundation of the city to Cato’s own death. Only fragments of Cato’s history survive; they reveal that Cato’s approach to the writing of history was rather unusual. Instead of referring to any individuals throughout Roman history by name, Cato referred to them by title or political position. As a result, his history was truly focused on Rome and aimed to glorify the accomplishments of Rome rather than individual Romans. Thankfully for modern historians, Cato’s experiment of nameless history did not catch on with subsequent Roman historians. Modern historians are able to reconstruct the story of the Romans from a variety of written and archaeological sources, but some of these sources present problems of which the historian must be aware. Similarly to the challenges modern historians face when studying Greek history, historians of Rome must at times engage in educated guessing when attempting to reconstruct a picture of Rome and Romans based on the limited evidence that is available.
Because the genre of historical writing started so late in Rome, few histories survive from the period of the Republic. Of these, the most famous (and the most voluminous) is the work of Livy, who wrote his Ab Urbe Condita (From the Foundation of the City) in the late first century BCE. Livy was very much an “armchair historian,” but he appears to have had access to a number of sources that are now lost, such as family histories from a number of aristocratic families. As the title indicates, Livy began his work with the legends about the founding of Rome. He continued his narrative down to his time, the age of Augustus, and the last known events in his work covered the year 9 BCE. Although Livy’s work consisted of 142 books, only about a quarter survives, including the first ten books, covering the regal period and the early republic and the narrative of the first two Punic Wars. Other prominent historians of the Republic whose works survive include Sallust, a contemporary of Caesar who turned to writing moralistic history after a frustrating political career, and Caesar himself, who wrote two books about his own campaigns: the Gallic Wars, about his conquest of Gaul in the 50’s BCE, and the Civil War, about his civil war against Pompey in 49 – 45 BCE.
The works of two prominent historians survive from the period of the Roman Empire. Tacitus, another politician-turned-historian, wrote in the early second century CE two works about the history of the Roman Empire in its first century of existence. The Annals covered the rule of the emperors Tiberius through Nero, while the Histories continued the narrative to the rule of the emperor Domitian. Significant portions of both works survive. Ammianus Marcellinus, a military officer writing in the late fourth century CE, saw himself as a successor of Tacitus, and composed a massive history of the Roman Empire from the end of Tacitus’ work to his own day. In addition, the sensationalizing biographer Suetonius, a contemporary of Tacitus, composed tabloid-style biographies of the first twelve emperors (from Caesar to Domitian). The anonymous Historia Augusta, composed sometime in the late Empire, provides similarly sensationalizing biographies of Roman emperors and some usurpers from Hadrian in the early second century CE to Carinus in the late third century CE.
In addition to these Roman historians and biographers, a number of historical works in Greek survive from the late Republic and the Empire that cover topics related to Roman history. To mention just a few examples, in the late first century BCE, Diodorus of Sicily wrote a massive universal history that includes key events of Roman history, alongside Greek history and mythology. The Greek biographer Plutarch, writing in the first century CE, paired for the sake of comparison biographies of famous Greeks and Romans; one exemplary such pairing is that of Alexander the Great and Julius Caesar. Josephus, a Jewish rebel leader turned Roman citizen, wrote the Jewish War, a detailed account of the disastrous Jewish revolt against Rome in the 60’s CE.
Works of history, however, are only one type of source that modern historians of Rome use. Other written sources include poems, novels, letters of politicians and other prominent figures, military and farming manuals, cookbooks, etc. For instance, one of the best sources for the political ideology of the Augustan age is Vergil’s epic poem Aeneid, which tells the story of the Trojan hero Aeneas and his struggle to reach Italy after the fall of Troy to found Rome. Arguably the single best source for everyday life in the Roman provinces under the Empire is Apuleius’ novel Metamorphoses, better known under the title Golden Ass. The novel is a fictional account of a man accidentally turned into a donkey, who tells the narrative of his travels through the Roman Empire in the late second century CE. And one of the best sources for the government of Roman provinces is the correspondence of Pliny the Younger, governor of the province of Bithynia on the shores of the Black Sea in 111 – 113 CE, with the emperor Trajan. To say the least, the job of the provincial governor, based on these letters, appears to have been decidedly unglamorous.
Early Christianity is one area of Roman history that has been especially well documented from its inception. The New Testament is an invaluable source, as it presents sources by early Christians about their own faith and its spread throughout the Roman Empire. A variety of popular heretical texts from the second and third centuries also survives and allows historians to reconstruct some of the dissenting views held in the early church. Writings in Greek and Latin by a number of influential figures in the early church, dubbed the Church Fathers, document the theological debates that resulted ultimately in the Nicene Creed. Starting in the second century CE, martyrdom accounts and saints’ lives provide admittedly semi-fictional and stylized biographies of individual believers. Finally, two prominent theologians in the Late Empire attempted to write (or re-write) Roman history specifically through a Christian lens. Eusebius, the Bishop of Caesarea in the fourth century CE, wrote the History of the Church, focusing on the history of Christianity from its beginnings to his day. Then in the early fifth century CE, Augustine, Bishop of Hippo in North Africa, wrote the City of God, a massive work covering history and legends of Rome from its beginnings to his day, in an attempt to show that Rome’s previous successes were due not to adherence to the pagan gods, but instead always to the Christian God’s mercy.
In addition to written sources of various kinds, archaeological sources provide further insight into Roman life in different periods. Examples of sources that survive include inscriptions, especially gravestones; traded goods, such as lamps or bricks, which allow historians to reconstruct the movement of goods across the empire; and a number of Roman towns and military camps.
One example of the random nature of how some sources were able to survive is the ancient site of Pompeii. The eruption of Vesuvius in 79 CE caused volcanic ash to rain down on the resort Roman town of Pompeii and the nearby town of Herculaneum, effectively burying both towns and preserving them completely for modern archaeologists. The tragedy for the Roman residents of the two towns at the time proved to be a modern archaeologist’s dream.
While, as the above summary shows, abundant sources of different types survive from different periods of Roman history, certain perspectives are difficult to reconstruct from our sources. For instance, slaves in the Roman world were as archaeologically invisible as in the Greek world. Likewise, very little evidence documents women’s lives before the rise of Christianity, and their voices are largely left out from Roman history. Other than epitaphs on their gravestones, most average Romans, in general, left no record of their lives, so our evidence is dominated by the history of the aristocracy. Still, the careful historian can gain at least some insight into these lesser-documented perspectives by gathering all references to them in sources that survive.
